Velazco DM, Hess A, Edwards-Callaway LN, Nair MN. Benchmarking the United States bison meat industry: stakeholder perceptions, production parameters, and live animal factors affecting meat quality. J Anim Sci 2024; 102:skae033. [PMID: 38347826 PMCID: PMC10924537 DOI: 10.1093/jas/skae033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 02/06/2024] [Indexed: 03/10/2024] Open
Abstract
The objectives of this study were 1) to understand stakeholder perceptions regarding the bison industry, 2) to benchmark live animal characteristics and production parameters of the bison industry, and 3) to identify live animal factors related to animal welfare and their effect on specific quality characteristics of bison meat. A survey was conducted both online and in-person at the National Bison Association Winter Conference (2022). Descriptive statistics were performed on a total of 110 surveys. Most stakeholders (94%, n = 104) agreed that the industry should continue to grow, and the majority (99%, 108) agreed that animal welfare impacts meat quality. Facility design (80%, n = 88), animal handling (78%, 86), employee training (56%, 62), and transportation duration (56%, 62) were selected as the factors that affect animal welfare. More than half of the stakeholders selected flavor (67%, n = 74) as the most important quality attribute of bison meat. For the in-plant antemortem and postmortem parameters data was collected from three plants in the United States over the course of a year. A total of 2,284 bison (bulls: n = 1,101; cows: n = 199; heifers: n = 984) were included in the study. Antemortem measurements such as distance traveled, vocalization, prod use, mobility, and head bumps were measured, followed by postmortem measurements that included bruise score, live weight, dressing percentage, ribeye area, and instrumental color. Approximately 97% of bison (n = 2,213) had at least one bruise. The average distance traveled from producer to slaughter plant was (mean ± SD; 823 ± 583 km) and the average dressing percentage was (mean ± SD; 60.5 ± 3.3%). Average (mean ± SD) fat thickness and ribeye area were 1.4 ± 1.1 cm and 62.6 ± 9.8 cm2, respectively. Approximately 30% (n = 676) of the bison in this study head bumped between 1 and 5 times in the restraining chute or the single-file gate before being stunned. Linear regression indicated that differences in lean a* were associated with plant, number of head bumps in the chute, ribeye area, fat thickness, live weight, and sex class (P < 0.05). Logistic regression indicated that season, sex class, live weight, plant, and season were associated with differences (P < 0.05) in bruising. These results can be used as a baseline for current production parameters and serve as the foundation for future research to monitor improvement.

Thermal Balance in Male Water Buffaloes Transported by Long and Short Journeys. Animals (Basel) 2023; 13:3274. [PMID: 37893998 PMCID: PMC10603650 DOI: 10.3390/ani13203274] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 10/14/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
Transport is a stressor that can cause physiological and metabolic imbalances in livestock, resulting in stress-induced hyperthermia. In water buffaloes, studies regarding the thermal state of animals during mobilization are scarce. Therefore, this study aimed to compare the thermal response of 1516 water buffaloes using infrared thermography (IRT) during 15 short trips (783 animals, 60,291 records, average duration = 50.33 min ± 5.48 min) and 14 long trips (733 animals, 56,441 records, average duration = 13.31 h ± 47.32 min). The surface temperature was assessed in 11 regions (periocular, lacrimal caruncle, nasal, lower eyelid, auricular, frontal-parietal, pelvic limb, torso, abdominal, lumbar, and thoracic) during seven phases from pasture to post-transport. It was found that the surface temperature of the periocular, lacrimal caruncle, nasal, auricular, frontal-parietal, pelvic limb, torso, abdominal, lumbar, and thoracic regions was significantly higher during SJs (+3 °C) when compared to LJs (p < 0.0001). In particular, the frontal-parietal region had a significant increase of 10 °C during the post-transport phase (p < 0.0001) in both groups, recording the highest temperatures during this phase. Likewise, a strong positive significant correlation between the different regions was found (r = 0.90, p < 0.0001). It is worth mentioning that the herding, loading, pre-, and post-transport phases were the ones where the greatest thermal response was recorded, possibly due to the influence of human interaction. Finally, a strong positive correlation (r above 0.9, p > 0.001) between the periocular, lacrimal caruncle, pinna, and pelvic limb was found. According to the results, SJ could be considered a stressful event that hinders thermal generation, contrarily to LJ.

Use of Moringa oleifera leaves (sole or combined with concentrate) in rabbit feeding: Effects on performance, carcass characteristics and meat quality attributes. Meat Sci 2023; 198:109108. [PMID: 36640718 DOI: 10.1016/j.meatsci.2023.109108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Revised: 01/06/2023] [Accepted: 01/06/2023] [Indexed: 01/09/2023]
Abstract
Sixty Chinchilla rabbits (28 days old) were divided into three equal groups (n = 20). Rabbits in MOL0 (control) were fed pellets containing 700 g cowpea hay/kg pellet as forage source, whereas rabbits in MOL700 and MOL950 were fed pellets containing 700 and 950 g moringa leaves/kg feed pellets, respectively. Average daily gain and feed conversion ratio was comparable in MOL700 and MOL0, however, it was higher in MOL950. Among the carcass traits, dressing percent was higher while, chilling loss was lower in MOL700 treatment. The Longissimus thoracis muscle of rabbits fed moringa leaves containing pellets (MOL700 and MOL950) had lower saturated fatty acid content, higher C18:3n-3 and total n-3 fatty acids along with lower thrombogenic index value. Hence, incorporating moringa leaves at 70% level is beneficial in terms of improved growth performance and functional attributes of meat than diet- containing sole moringa leaves.

Life (Basel) 2023; 13:life13040927. [PMID: 37109456 PMCID: PMC10146898 DOI: 10.3390/life13040927] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 03/20/2023] [Accepted: 03/30/2023] [Indexed: 04/05/2023] Open
Abstract
Humic substances with a high proportion of humic acids (more than 40%) have been classified by the European Commission as feed materials that can be used in animal nutrition since 2013. A protective effect on the intestinal mucosa, as well as anti-inflammatory, adsorptive and antimicrobial properties, were recorded. Nutrient absorption, nutritional status and the immune response in chickens supplemented with HSs were significantly improved. HSs have the ability to enhance protein digestion as well as the utilization of calcium and trace elements. They are known to improve feed digestibility as a result of maintaining an optimal pH in the gut, leading to lower levels of nitrogen excretion and less odor in the husbandry environment. HSs not only increase digestibility and result in greater utilization of the feed ration but also improve the overall quality of the meat produced. They increase the protein content and reduce the fat content in breast muscles. They also contribute to improving the sensory characteristics of the meat produced. Their antioxidant properties improve the oxidative stability of meat during storage. The influence of HSs on fatty acid composition may be one of the reasons that meat has a more beneficial effect on the health of consumers.

Abstract
IntroductionThe pre-slaughter management period is a critical juncture in the beef supply chain, having implications not only for animal welfare and product quality, but also for profitability. During this period, cattle are exposed to many stressors in a short time, many of which have been shown to impact meat quality. Understanding how cattle management during this terminal step in the production chain affects meat quality and economic outcomes is crucial.MethodsThe objective of this study was to investigate, synthesize, and report on research evaluating the impact of management factors during the pre-slaughter period on beef meat quality. A systematic approach was used to search for peer-reviewed and primary studies published in English in CAB Abstracts, PubMed, and Web of Science. A total of 3,217 non-duplicate records were screened for eligibility; articles were deemed eligible for inclusion if they included beef cattle in the pre-slaughter period and reported at least one meat quality outcome. After three screening rounds, 85 articles met all inclusion criteria. Data pertinent to the scoping review’s aims were extracted, including study location, population characteristics, pre-slaughter factors reported, and outcomes of interest.ResultsEurope (35, 41%) and South America (21, 25%) represented approximately two-thirds of the studies. Bulls (37, 43.5%) and steers (34, 40.0%) were the most reported sex classes, with the most frequent breed types reported as predominantly British or Continental and Bos indicus breeds (24, 28.2%; 24, 28.2%, respectively). Transportation (n=46), lairage (n=36), and handling (n=35) practices were the most reported pre-slaughter factors. Overall, 59 studies reported pH as an outcome of interest – almost double that of the next highest outcome, bruising (n=35). Muscle pH was most assessed with predictors at the abattoir (n=37); conversely, the effects of transportation were most evaluated on bruising (n=23).DiscussionA trend across all the categories was that there were relatively few studies evaluating the impact of pre-transport factors on meat quality. Charting the relevant literature is a critical step towards understanding the relationship between pre-slaughter management and end-product quality; doing so will help industry stakeholders in the beef production chain optimize management practices that improve meat quality and enhance profitability.

Abstract
IntroductionThe impact of pre-slaughter management practices on fed beef cattle welfare is a multifaceted and well researched subject matter. Factors such as transportation, handling, lairage time and several animal characteristics can directly impact the cattle’s behavior, mobility, blood lactate and cortisol levels, likelihood of injury and ultimately overall cattle welfare. Animal welfare continues to grow as a critical component of slaughter in the fed beef industry, yet a formal review of related research does not exist.MethodsA scoping review was performed in order to (1) catalog pre-slaughter management factors that impact fed beef cattle welfare at the time of slaughter, (2) identify indicators used to evaluate the impact of pre-slaughter management on fed beef cattle welfare at slaughter, and (3) gain further understanding of the relationship between pre-slaughter management factors and fed beef cattle welfare outcome indicators at slaughter. Three data bases were ultimately searched: PubMed, CAB Abstracts, and Web of Science. The concepts used in the database searches were the population of interest (i.e., fed beef cattle), the location in the supply chain, preslaughter management factors, and welfare outcomes.ResultsA total of 69 studies were included in final analysis for this review, including studies from six geographic regions around the globe. Studies involving alternative slaughter methods (e.g., religious stunning or mobile slaughter) were not included in the formal analysis of this review, but still merited an in-depth discussion within this paper. After reviewing the studies, a total of 37 pre-slaughter factors and 69 indicators of welfare were measured throughout. Pre-slaughter management factors were then categorized by: animal characteristics; environmental characteristics; handling; lairage; transportation; and water/feed. Outcomeindicators of welfare were categorized into: behaviors; health, injury and disease; physiological; and stunning and insensibility.DiscussionPre-slaughter factors relating to transportation and handling, and welfare outcomes measured by behaviors and physiology were of the most researched throughout the studies.The results of this review offer a catalogue of commonly researched factors and indicators of welfare measured during the pre-slaughter phase, as well ast he relationships between them. This review also offers further substantial evidence that a multitude of events in the pre-slaughter phase affect fed beef cattle welfare and a collection of highly applicable welfare indicators to expedite further research on the effects of pre-slaughter factors and the application of improved practices.

Abstract
The aim was to investigate the effects of duration of lairage period and breed on behaviors of beef cattle and on stockperson handling actions toward cattle in the slaughter corridor. A total of 85 beef cattle (61 Simmental, 24 Brown Swiss) were allocated to 4 trial groups according to the duration of lairage period (24 h, 15 h, 1 h and no lairage). Animal behaviors and stockperson's handling actions were video recorded during the passage of animal through the slaughter corridor. Time spent in the slaughter corridor ranged between 4.64 and 16.82 min, and cattle lairaged 15 h spent more time in the slaughter corridor than the other groups (P < 0.05). Breed and lairage group had no effect on AWBEH (animal behavior) and AWACT (stockperson actions) scores and frequencies of animal behaviors, except butting. Beef cattle slaughtered without transport and lairage expressed less butting behavior compared to other lairage groups (P < 0.05). The most observed stockperson handling actions were goading, beating, tapping, and tail twisting, respectively. Cattle from L-15 group were exposed to more beating and prodding actions while cattle from L-24 h group were exposed to more pulling action. In conclusion, increasing the lairage period did not contribute to the reduction of stockperson interventions and cattle behaviors indicative of poor welfare in the slaughter corridor. Both stockperson training and facility improvements would greatly improve cattle welfare.

Abstract
Social pressure on increased protection and welfare of animals results mainly from the initiative of people living in the urbanized parts of the world. The respect for the right to freedom of religion, which is indisputably one of the fundamental liberal rights, must be taken into account. The right to freedom to religion also includes the right to follow a religion’s dietary recommendations. The aim of the literature analysis was to systematize the knowledge on the ethical aspects and quality of meat obtained from carcasses of animals subjected to conventional and ritual slaughter. Consistent with the importance of ritual slaughter for humans of two major faiths (Islam and Judaism), it is important that scientists be objective when evaluating these practices from an animal welfare and meat quality point of view. To evaluate the welfare of the slaughtered animal, it is necessary to openly discuss ritual slaughter and the improvement of its methods. The quality of meat and the degree of bleeding of animals do not always correlate with the ritual slaughter method used.

Abstract
Comprehensive characterization of the post-mortem muscle proteome defines a fundamental goal in meat proteomics. During the last decade, proteomics tools have been applied in the field of foodomics to help decipher factors underpinning meat quality variations and to enlighten us, through data-driven methods, on the underlying mechanisms leading to meat quality defects such as dark-cutting meat known also as dark, firm and dry (DFD) meat. In cattle, several proteomics studies have focused on the extent to which changes in the post-mortem muscle proteome relate to dark-cutting beef development. The present data-mining study firstly reviews proteomics studies which investigated dark-cutting beef, and secondly, gathers the protein biomarkers that differ between dark-cutting versus beef with normal-pH in a unique repertoire. A list of 130 proteins from eight eligible studies was curated and mined through bioinformatics for Gene Ontology annotations, molecular pathways enrichments, secretome analysis and biological pathways comparisons to normal beef color from a previous meta-analysis. The major biological pathways underpinning dark-cutting beef at the proteome level have been described and deeply discussed in this integromics study.

Abstract
Simple Summary The transport and general handling of slaughter animals are associated with a series of events that cause stressful and unfavorable conditions that can compromise animal welfare. All these stressful events start at the farm and end with the death of the animal. In this experiment, we evaluated the effect of two finishing strategies and two contrasting lairage times through the combination of several indicators regarding productivity, physiology, behavior and postmortem variables. Individual temperaments and their impact on welfare and carcass quality were also considered. Animal welfare was not compromised in any diet during the finishing period. Individual temperament had a positive impact on the productivity and on all physiological indicators at different preslaughter stages. For that reason, we consider that it should be given paramount importance when talking about animal welfare. According to our results, with pasture-based animals, without fasting on the farm and after a short time of transportation (3.5 h), a longer preslaughter resting time (15 vs. 3 h) is desirable from the animal welfare perspective. Furthermore, our results suggest that this longer resting period, would also be more convenient from the carcass quality perspective. Abstract The objective of this experiment was to evaluate the effect of two different pasture-based finishing strategies and lairage time on steers welfare in Uruguayan conditions. Sixty Hereford (H) and Braford (B) steers were assigned to two different diets for finishing purposes: (D1) native pasture plus corn grain (1% of live weight) (H n = 15, B n = 15) and (D2) high-quality pasture (H n = 15, B n = 15). The average daily gain was registered every 14 days, and temperaments were individually assessed one week before slaughter by three individual tests: crush score, flight time and exit speed, building a multicriterial temperament index (TIndex). Animals were slaughtered the same day in two groups (50% from D1 and 50% from D2 in each group) after traveling for 3.5 h and staying 15 (long lairage) and 3 h (short lairage) in the lairage pens, respectively. The behaviors were observed during lairage, and physiological indicators were used to assess stress at the farm after transport, after lairage and at slaughter. Bruises incidence and final pH were registered at the abattoir as a means of assessing the overall animal welfare. Calmer animals had higher average daily gains with no differences either between diets or between breeds. Calmer animals also had a lower stress response during all preslaughter stages, regardless of the time in lairage. Transport did not imply psychological stress (cortisol) for any slaughter group, but physical stress was evident after transport in both groups through NEFA and CPK increases. Bruise incidences did not differ between lairage groups. The short lairage group did not have enough time to cope with the environment before slaughter, with the consequent deleterious effects on the carcass pH. Animals from the long lairage group had a higher metabolic response shown through NEFA values, but they had enough time to rest and recover overnight, reaching final pH values lower than 5.8, considered the upper limit of the normal range. According to this experiment, with pasture-based animals without fasting on the farm and after 3.5 h of transportation, a resting period of 15 h in lairage should be better than a 3-h one.

Abstract
Pre-slaughter fasting duration affect blood parameters related to stress and metabolism, decrease live and carcass weights and impact beef quality of cattle. In three experiments, 1100 steers and heifers, finished on feedlot or on pasture, were evaluated to assess the influence of the site and duration of fasting before slaughter on physiological, carcass and meat quality traits. Cattle were allocated to one of two fasting duration - long (23-29 h) or short (2-6 h) - and to one of two sites of fasting- farm or abattoir. All animals had access to water ad libitum until slaughter, except during transportation. Cattle were assigned to two (long fasting on abattoir/normal lairage time, short fasting on farm/minimal lairage time) or three (long fasting on abattoir/normal lairage time, short fasting on farm/minimal lairage time, long fasting on farm/minimal lairage time) treatments. Seventeen slaughters were considered in a randomized complete block design. There was no effect of the site of fasting on any variable. Cattle with short fasting duration had higher carcass weights and water consumption than those under long fasting duration. Haematocrit, globulin, total protein, and lactate dehydrogenase at the time of slaughter increased with fasting duration. There was no effect of the duration of fasting on blood ions, meat quality traits, urine pH, liver weight and volume, and skin dry matter. A reduction in the fasting duration returned to farmers and abattoirs 1.2% additional kilograms of carcass, suggesting an improvement in animal welfare according to a better hydration level of cattle at the time of slaughter.

Abstract
The killing of cattle for human consumption (slaughtering) can take place in a slaughterhouse or on farm. The processes of slaughtering that were assessed for welfare, from the arrival of cattle until their death (including slaughtering without stunning), were grouped into three main phases: pre-stunning (including arrival, unloading from the truck, lairage, handling and moving of cattle); stunning (including restraint); and bleeding. Stunning methods were grouped into two categories: mechanical and electrical. Twelve welfare consequences that cattle may be exposed to during slaughter were identified: heat stress, cold stress, fatigue, prolonged thirst, prolonged hunger, impeded movement, restriction of movements, resting problems (inability to rest or discomfort during resting), social stress, pain, fear and distress. Welfare consequences and their relevant animal-based measures are described. In total, 40 welfare hazards that could occur during slaughter were identified and characterised, most of them related to stunning and bleeding. Staff were identified as the origin of 39 hazards, which were attributed to the lack of appropriate skill sets needed to perform tasks or to fatigue. Measures to prevent and correct hazards were identified, and structural and managerial measures were identified as those with a crucial role in prevention. Outcome tables linking hazards, welfare consequences, animal-based measures, origin of hazards, and preventive and corrective measures were developed for each process. Mitigation measures to minimise welfare consequences are proposed.

Abstract
The objective of this study was to examine sex and breed effects on heat shock protein 70 (HSPA1A), blood stress indicators and meat quality attributes of lambs. A hundred male and female lambs from the Dorper (n = 50) and Merino (n = 50) breeds were used in this study. Breed and sex had a significant (p < 0.05) effect on the levels of plasma HSPA1A and lactate; where the Merino lambs had higher levels than Dorper. The female lambs had higher levels of plasma HSPA1A than male lambs. Significant sex and breed interactions (p < 0.05) on the levels of plasma HSPA1A were seen. Females had higher (p < 0.05) pHu than males. Dorper lambs had higher (p < 0.05) pH45, meat lightness, thawing loss and tougher meat the Merino breed. Significant correlations were found amongst plasma stress indicators and meat quality attributes. The results indicate that female lambs were more stressed by the pre-slaughter period than males, while the Merino had a higher physiological stress response compared to the Dorper. However, the Dorper breed produced tougher meat.

Analysis of Stress Indicators for Evaluation of Animal Welfare and Meat Quality in Traditional and Jewish Slaughtering. Animals (Basel) 2018; 8:ani8040043.

Abstract
Simple Summary Cortisol and catecholamines (dopamine, norepinephrine and epinephrine) are released in response to stress and directly stimulate glycogen mobilization, thus influencing meat acidification. The aim of the study was to estimate and compare these stress indicators to evaluate the welfare of beef cattle, subjected to either traditional slaughtering (with stunning) or to slaughtering with religious Jewish rite (without stunning). Significant differences in plasma cortisol and catecholamine levels were observed during exsanguination by monitoring animals in the pre-slaughtering (before and after transportation) and slaughtering phases. Cortisol, dopamine and norepinephrine, but not epinephrine, were markedly higher in the animals slaughtered by the religious rite. Pursuing animal welfare in the religious slaughtering procedures could produce advantages in terms of hygiene, organoleptic quality and shelf life of meat. Abstract Sixty Charolais male beef cattle of eight months of age were divided into two groups according to the slaughtering method, i.e., traditional or Kosher (religious Jewish rite). The aim of the study was to detect and compare the plasma concentrations of cortisol and catecholamines (dopamine, norepinephrine and epinephrine), by Elisa and HPLC test. These four stress indicators were evaluated during three different stages of each animal productive life: on the farm (step 1), after transportation (step 2) and during bleeding (step 3). The patterns of the parameters measured were similar and, interestingly, revealed significant changes throughout the three steps considered. The greatest variation between the two methods of slaughtering was observed in step 3, where we found a statistically significant difference with all the parameters except epinephrine. In the animals slaughtered by the religious rite, cortisol, dopamine, norepinephrine and epinephrine were 68.70 ± 30.61 nmol/L; 868.43 ± 508.52 ng/L; 3776.20 ± 1918.44 ng/L; and 4352.20 ± 3730.15 ng/L, respectively, versus 45.08 ± 14.15 nmol/L; 513.87 ± 286.32 ng/L; 3425.57 ± 1777.39 ng/L; and 3279.97 ± 1954.53 ng/L, respectively, in the other animals. This suggests that the animals slaughtered by the Kosher rite are subjected to higher stress conditions at the exsanguination phase. The animals slaughtered by the religious Jewish rite showed lower cortisol and catecholamine levels on the farm (step 1) and after transportation to the slaughterhouse (step 2). This was likely because the animals selected at the end of step 1 by the Rabbis for the religious rite are usually the most docile and gentle.

Abstract
This study investigated the effects of animal, carcass and muscle characteristics on initial color traits of steaks from 887 Charolais cattle. First, the fixed factors of year of birth, experiment and sex had strong impacts on color traits. From the covariates, increased age lead to intense color (low h*, -1.55 units) and darker and vivid meat (high a*, b* and C*: +4.56, +3.41 and +5.61, respectively). Increases in fatness score and carcass fat weight were associated with increases in a*, b* and C* (redness; +2.90 to +4.06 for a*; yellowness; +2.60 to +3.76 for b*; and vividness, +3.87 to +5.49 for C*) and a darker colored lean (L*; -1.56 to -3.23). As pH24h increased, a* (less red) and C* (less vivid) decreased (-3.06), whereas hue angle increased (+2.69) leading to poorer color. The selection of animals for high degree of muscularity or slaughter weight resulted in lighter and darker meat, respectively. The studied covariates could be used as indicators of Charolais beef color traits.

Abstract
The objective of the study was to determine the factors related to beef cattle carcass bruises. Handling, transportation and unloading data from cattle purchased by a slaughterhouse in southern Brazil were obtained to assess their associations with carcass bruising (occurrence or not) and the number of bruises per load. In total, 4338 carcasses from 142 loads of cattle purchased by the company were assessed. The females were cull cows and the males were steers. Independent variables studied included sex (females or males), loading facilities (good, regular or poor), cattle handling (good, regular or poor), transport time from the farm to the slaughterhouse (hours), hauling-truck types, truck animal-load density (kg/m2) and slaughterhouse unloading time (min). For both traits studied (carcasses bruised and number of bruises per load), all of the independent variables showed a significant (P < 0.05) effect. Animal sex is the most important factor on carcass bruising and the number of bruises per load, with females showing 91% more bruises than males. Moderate load densities caused greater bruising than did low (<370 kg/m2) and high (>431 kg/m2) densities. In general, greater bruising was caused by longer transport and unloading times. Bruises were reduced by improving loading facilities from regular to good. Transportation in vehicles with higher load capacities (animal numbers) resulted in greater bruising. Therefore, special handling practices and personnel training measures should be undertaken to mitigate losses pre-slaughter, especially when handling female cattle, which are more vulnerable to developing carcass bruises, possibly due to higher cow reactivity.

Abstract
Response to pre-slaughter stress differs depending on animal-related factors such as sex and breed. The present study investigated breed and sex effects on plasma stress indicators, muscle glycolytic potential and the quality of meat from 8-month-old lambs of Dorper (n = 52) and Merino (n = 48) breeds. Blood samples were collected at exsanguination for the measurement of glucose, lactate and cortisol levels. Representative meat samples were collected from the Muscularis longissimus thoracis et lumborum for the measurement of glycogen, lactate, glycolytic potential levels, pH and colour coordinates. Results showed that the ewes had higher levels of plasma lactate, cortisol and meat pH than the rams, meaning that the ewes perceived the slaughter process to be more stressful compared with the rams. The Dorper also had higher levels of plasma lactate and lower meat lightness compared with the Merino breed. Significant sex and breed interactions on the meat pH45 min and colour coordinates were observed. Significant correlations were found among plasma cortisol, pH and colour. The results indicate that ewes and Dorper were more stressed than the rams and Merino breed respectively. In this study it can be concluded that the ewes and Dorper breed perceived the slaughter process to be more stressful compared with the rams and Merino breed.

Abstract
Animal welfare has become an important subject of public, economic and political concern, leading to the need to validate indicators that are feasible to use at abattoirs. A systematic review was carried out, which identified 72 cattle welfare indicators (CWI) that were classified into four categories (physiological, morphometric, behavioral and meat quality). Their validity and feasibility for use in abattoirs were evaluated as potential measures of cattle welfare during transportation to the abattoir and at the abattoir itself. Several highly valid indicators were identified that are useful to assess welfare at abattoirs, including body condition score, human-animal interactions, vocalizations, falling, carcass bruising, and meat pH. In addition, some intermediate valid indicators are useful and should be investigated further. Information along the food chain could be used systematically to provide a basis for a more-risk-based meat inspection. An integrated system based on the use of key indicators defined for each inspection step with the setting of alarm thresholds could be implemented.

Abstract
The study determined the activities of creatine kinase (CK) and lactate dehydrogenase (LDH) in transported cattle as indicators of welfare and how they relate to beef quality. A total of 219 (n=219) (85 Beefmaster, 48 Charolaise, 32 Holstein-Friesian and 54 nondescript) cattle brought to the abattoir for slaughter were used in the study. Disposable vacutainer tubes with anticoagulant (ethylenediaminetetraacetic acid) were used to collect 4 ml of blood samples to determine the activities of CK and LDH. The measurements of pHu and colour coordinates (L*, a* and b*) were carried out at 48 h after slaughter on the representative samples of muscularis longissimuss thoracis et. lumborum (LTL). Longer distance travelled by cattle had a significant effect (P3000 to 5000) and those that travelled for 1263 km had lower CK activities (1000). The activities of LDH were observed in cattle that travelled for 366 and 1012 km (7000) and for those that travelled for 877 and 922 km (6000). Results of the principal component analysis showed that the first three principal components (PCs) explained about 53% of the total variability. The first PC was correlated with meat quality attributes (pHu, Tm, a* and b* values). The activities of CK and LDH were related and useful to define the second PC. However, CK and LDH were not related to beef quality. Therefore, CK and LDH can be used as indicators of welfare in slaughter cattle but cannot be used to predict the quality of meat.

Abstract
Background During the pre-slaughter period, animals experience novel environment and procedures which may cause reduced welfare and suffering. Over the last decades, the slaughter industry has restructured into fewer and larger abattoirs, implying potential risks of transport stress, injuries, and impaired animal welfare. Since recently, however, there is growing interest in small-scale slaughter to supply locally or regionally produced meat. Risk managers at all levels thus need to assess animal welfare risks also at small-scale operations. This study aimed to assess risks of poor animal welfare at small-scale lamb slaughter (≤5000 sheep/year and ≤70 sheep/day) in Norway, Iceland, Sweden and Finland, and to compare these risks to large-scale industrial slaughter. Assessment was done applying an individual expert opinion approach during a 2-day workshop. Nine experts in lamb slaughter procedures, behaviour, physiology, health, scoring schemes and/or risk assessment provided estimates of exposure, likelihood of negative consequences following exposure, and intensity and duration of negative consequences for 71 hazards. The methods applied mainly adhered to the risk assessment guidelines of the European Food Safety Authority. The list of hazards was modified from an earlier study and distributed to the experts before the assessment. No other literature was reviewed specifically for the purpose of the assessment. Results The highest risks to animal welfare identified in both small- and large-scale slaughter were related to inadequate conditions during overnight lairage at the slaughter plant. For most hazards, risk estimates were lower in small-scale slaughter. The reverse was true for splitting of groups and separation of one sheep from the group. Conclusions Small-scale slaughter has a potential for improved sheep welfare in comparison with large-scale industrial slaughter. Keeping the animals overnight at the slaughterhouse and prolonged fasting before slaughter should be avoided. Solutions include continuing education and training of stockpersons and, especially in large-scale slaughter, application of existing techniques for efficient transport logistics that minimise stress.

Abstract
Standard practice in the dairy industry is to separate the calf and dam immediately after birth and raise calves in individual pens during the milk-feeding period. In nature and in extensive beef systems, the young calf lives in a complex social environment. Social isolation during infancy has been associated with negative effects, including abnormal behavior and developmental problems, in a range of species. Here, we review empirical work on the social development of calves and the effects of social isolation in calves and other species; this evidence indicates that calves reared in isolation have deficient social skills, difficulties in coping with novel situations, as well as specific cognitive deficits. We also review the practices associated with group housing of dairy calves, and discuss problems and suggested solutions, especially related to cross-sucking, competition, aggression, and disease. The studies reviewed indicate that social housing improves solid feed intakes and calf weight gains before and after calves are weaned from milk to solid feed. Evidence regarding the effects of social housing on calf health is mixed, with some studies showing increased risk of disease and other studies showing no difference or even improved health outcomes for grouped calves. We conclude that there is strong and consistent evidence of behavioral and developmental harm associated with individual housing in dairy calves, that social housing improves intakes and weight gains, and that health risks associated with grouping can be mitigated with appropriate management.

Genetic variants in glucocorticoid and mineralocorticoid receptors are associated with concentrations of plasma cortisol, muscle glycogen content, and meat quality traits in male Nellore cattle. Domest Anim Endocrinol 2015; 51:105-13. [PMID: 25617989 DOI: 10.1016/j.domaniend.2014.12.004] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2014] [Revised: 12/11/2014] [Accepted: 12/12/2014] [Indexed: 11/23/2022]
Abstract
The glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) are key components in the regulation of the hypothalamic-pituitary-adrenal neuroendocrine axis and coordinate the physiological response to stress agents to reestablish homeostasis. Genetic variations of GR (NR3C1) and MR (NR3C2) genes could explain the alterations in animals to adapt to challenges, and therefore, their influence on production traits. The present study aimed to identify single-nucleotide polymorphisms (SNPs) in the bovine NR3C1 and NR3C2 genes and explore their associations to relevant traits of beef cattle production. Genotypes and phenotypes were collected from 241 male Nellore cattle (119 noncastrated and 122 castrated surgically) with an average of 24 ± 1.2 mo of age and live weight of 508 ± 39 kg. The traits evaluated were concentrations of plasma adrenocorticotropic hormone (ACTH) and cortisol, muscle glycogen and lactate content, and pH, color, cooking loss, and shear force of longissimus thoracis measured on the 1st, 7th, and 14th days postmortem. Five SNPs were identified, 2 in the NR3C1 gene and 3 in the NR3C2 gene. There was an associative relationship between the SNP NR3C1_1 g.3293A>G and postmortem plasma concentration of cortisol (P = 0.0008). The SNPs NR3C2_1 g.115T>C and NR3C2_2 g.570T>C were associated with muscle glycogen content (P = 0.0306 and P = 0.0158), postmortem plasma concentration of ACTH (P = 0.0118 and P = 0.0095), and cooking loss of the steak aged 1 d (P = 0.0398 and P = 0.0423). Haplotype analysis showed associations of GR haplotypes with postmortem plasma concentrations of cortisol and MR haplotypes with meat color, cooking losses, muscle glycogen content, and plasma concentrations of ACTH. The associations observed in the present study show that SNPs in GR and MR genes are related with changes of hypothalamic-pituitary-adrenal axis activity and metabolic profile in cattle, leading to individual variation in meat quality traits.

Abstract
The objective of the study was to determine the effects of animal related factors on bruising in slaughter cattle, creatine kinase (CK) and beef quality. Three hundred and twenty one cattle from three breeds (108 Bonsmara, 130 Beefmaster and 83 Brahman) were used in this study. The animals were grouped as follows: Group 1 (16 months old), Group 2 (18 months old) and Group 3 (24 months old). At exsanguinations, blood samples for CK determination were collected using disposable vacutainer tubes. Muscularis longissimus thoracis et lumborum (LTL) was collected 24 h after slaughter to determine the colour (L*, a*, and b*) and ultimate pH (pHu) of beef. Breed, sex and age had significant effects (p<0.05) on bruising score, CK levels and beef quality. Bonsmara breed had the highest (80%) bruising score percentage, CK (705.3±80.57 U/L) and pHu (6.3±0.05) values while the Bonsmara had the highest L* (24.8±0.78) a* (17.5±0.53) and b* (12.8±0.53) values. Higher CK levels were also observed in winter compared to summer, spring and autumn respectively. Therefore, animal factors (sex, breed and animal age at slaughter) contribute to the development of bruises and have an effect on the levels of CK and meat quality. It was also concluded that there is no significant relationship between meat parameters (L,* a*, and b*) and CK levels.

Abstract
Public sensitivity towards animal welfare has risen in recent years. Uruguay is a primary meat exporter. Therefore, it is compulsory not only to provide good quality and safe meat, but also to project a welfare friendly image. Uruguayan meat production systems are mainly based on rangeland pastures but, due to international meat prices and the opening of new markets, intensive fattening systems increased. These systems include a wide range of feeding alternatives between pasture and concentrate utilization, involving differences in terms of animal welfare, carcass and meat quality, that require to be studied. Accordingly, some husbandry practices associated mainly with extensive systems must be evaluated, as well as their applicability to international recommendations related to pre-slaughter handling which may not be suitable for local conditions. In the present paper we share scientific results related to the impact of different production systems, husbandry practices and pre-slaughter procedures associated to animal welfare and meat quality in Uruguayan conditions.

Abstract
Ostrich (Struthio camelus) production is a relatively young industry and there has been little research on ostrich welfare during pretransport handling and the transportation process. A heavy body with a high center of gravity makes ostriches' handling and transportation problems different from other livestock. The main objective of this study was to investigate the effects of the pretransport holding time duration on ostrich behavior and physiological responses. A second objective was to identify and validate behavioral indicator(s) that could be used to identify stressed birds during pretransport handling. Prior to shipping, twenty-four 2.5-yr-old ostriches were moved into a holding pen. Birds were then individually restrained, hooded, and walked from the holding pen (approximately 12 min/bird) to a sampling pen (visually isolated from the holding pen) where they were weighed and a 10-mL blood sample obtained. A second blood sample was taken from each bird after a 1,100-km transportation. Blood samples were analyzed for concentrations of blood metabolites, enzymes, corticosterone, and white blood cell and differential counts. Behavioral responses and physical damages of ostriches were also recorded before and after transport. Results indicated that birds that spent longer time in the pretransport holding pen had higher pretransport plasma concentrations of aspartate aminotransferase, alanine aminotransferase, sodium, and packed cell volume. Immobile sitting behavior, observed in 5 out of the last 11 birds handled, was positively correlated with higher pretransport handling stress, higher posttransport aspartate aminotransferase, alanine aminotransferase, creatine phosphokinase, and glucose concentrations, and transport losses. Knowledge of pretransport handling impacts on ostrich stress and availability of behavioral indicators (e.g., immobile sitting response) could be used to improve handing processes, thereby decreasing potential weight loss, injury, and mortality.

Abstract
Appropriate management of an ostrich's exposure to stressors during preslaughter handling and transport practices can improve its well-being and product quality. Because of the lack of information about ostrich farming and transportation in North America and lack of developed Codes of Practice for ratite transport in Canada and the United States, the first objective of our research was to identify current preslaughter handling and transport practices of the ostrich industry in Canada and the United States, and to identify potential welfare issues based on the current practices. The second objective of this research was to review ostrich transport welfare standards and guidelines from Australia, European Union, New Zealand, and South Africa to investigate if those guidelines are applicable to Canadian and American ostrich production systems. Preliminary producer interviews, on-farm visits, and literature review information sources were used to design a producer questionnaire that was used to survey producers by Internet and mail surveying methods to identify existing ostrich transport norms in Canada and the United States. Based on the results of our producer survey and review of the transport standards and guidelines, we conclude that following factors are potential ostrich handling and transport welfare issues in Canada and the United States: lack of scientific information about welfare of ostriches during handling and transport; unfamiliarity of handlers and birds with handling and transport practices; not considering birds' social bounds, sex, behavior, and physical state in mixing them during handling and transport process; lack of an established specific maximum water and feed withdrawal duration for ostrich transport in Canada and the United States; lack of a specific vehicle designed for ratite transportation in Canada and the United States considering different physical body characteristics of ostriches compared with other species; exposure of birds to natural light during transport inside the trailer; overcrowding; and long transportation in Canada and the United States. Results of this research will contribute toward developing Codes of Practice for preslaughter handling, transportation, and slaughter of ostriches in Canada and the United States.

Abstract
The effect of slaughter at arrival (L0) or after 3 (L3), 6 (L6), 12 (L12) h of lairage on carcass and meat quality of suckling lambs has been studied. Lairage time had a slight effect on carcass quality traits, but most of the meat quality parameters at 24h post mortem were affected. Weight losses increased and glycogen content of liver and longissimus muscle decreased as lairage time increased. Longissimus muscle from L3 lambs had the highest pH, shear force and toughness and the lowest b* and C* values, at 24h post mortem. L3 and L6 had the higher proportion of expelled juice, or low water holding capacity (WHC), at 24h post mortem. Texture parameters and WHC were similar among groups after 5 days of storage. Despite the fact that the effects of lairage time on meat quality disappears after storage, from the point of view of weight losses the slaughter of suckling lambs at arrival is recommended.

Abstract
The objective of this study was to determine the effects of three lairage times (24 h, 48 h and 72 h) on the meat quality of tame trained to lead Hungarian Simmental bulls subjected to long commercial transportation of approximately 1800 km. A total of 30 bulls, with an average age of 24 months, were used. During the lairage, bulls received 0.5 kg concentrate feed per animal per day and ad libitum access to the hay and water. As the lairage duration increased, the pH(ult) decreased (P<0.05). Bulls lairaged for 24 h had lower L*, b* and H* values than those lairaged for 48 h and 72 h (P<0.05). The effect of lairage time on WHC, cooking loss and Warner-Bratzler shear force values was not significant. The b* value was considered the best predictor of muscle pH(ult). In conclusion, 72 h quiet lairage time is recommended after transportation in order to prevent the adverse effects of transportation on meat quality.

Abstract
The aim of this study was investigate risk factors as possible causes for bruising and high muscle pH under commercial operating conditions in Colombia. Data was recorded for 86 journeys referring to 1179 animals. Carcasses were analyzed in terms of muscle pH and bruises (site, size, severity and shape). Our results indicate that truck load density, stops during transportation of cattle and the lairage time at the plant increased the risk of bruises appearing on carcasses. A lairage time of 18 to 24h at the plant increased the prevalence of bruises 2.1 times compared to lairage periods of between 12 and 18 h. Furthermore, intermittent stops during transit are a risk factor for the increase in the incidence of bruises. However, the transport time (up to 4h) was not related to the presence of bruises and high muscle pH. Finally, steers were found to have less risk of presenting a high muscle pH.

Abstract
The purpose of this study was to compare the effect of different transport distances on ostrich meat quality parameters, weight loss, and dressing percentage. Twenty-four ostriches were transported for 0 (T0), 60 (T60) and 600 (T600) km before being slaughtered. There was a significant difference (P = 0.038) in the percentage liveweight loss during transport and lairage between T60 km (2.4 ± 2.185%) and T600 km (8.13 ± 1.156%), respectively. There was also a significant difference (P = 0.003) in dressing percentage (farm weight to cold carcass weight) between the two abovementioned groups (T60 = 49.77%; T600 = 46.86%). Treatments also had a significant effect (P < 0.05) on ultimate pH (pHu), with the ostriches that did not travel exhibiting the lowest average pHu (5.77 ± 0.053) and the birds that travelled 600 km having the highest average pHu (6.11 ± 0.053). No differences (P > 0.05) were found in shear force and percentage cooking loss between the treatments, although all three treatments differed significantly (P < 0.05) from each other in drip loss (T0 km = 0.40%; T60 km = 1.36%; T600 km = 0.97%). Significant differences (P < 0.05) were found for L*, b* and hue-angle colour ordinates between the three treatments, while there were no differences (P > 0.05) in a* and chroma values. A significant correlation was found between hue angle (r = 0.528; P = 0.008) and pHu. The results of this study indicate that ostrich transport distance influences liveweight loss and meat quality.

Abstract
Thirty Kivircik lambs were used to investigate effect of pre-slaughter treatment on certain haematological and biochemical parameters, carcass and meat quality characteristics. Lambs were divided into three treatments: 75 min transport and lairage for 18 h (TS-L18 h); 75 min transport and lairage for 30 min (TS-L30 min) and no pre-slaughter transport and lairage for 30 min (NTS). Treatment, as a main effect, did not influence haematological and biochemical parameters, but sampling time significantly affected these parameters, except total protein. Plasma cortisol concentration at exsanguination in TS-18 h, TS-30 min and NTS treatments were 117.34, 119.23 and 72.51 ng/ml, respectively. pH of longissimus dorsi muscle was higher in TS-L30 min than other treatments. TS-L30 min lambs had the highest shear force value, the lowest WHC and cooking loss. TS-L30 min treatment yielded the darkest meat immediately after cutting and 1 h later. Meat redness, yellowness and chroma values were similar in treatments.

Abstract
Sixty Hereford (H) and Braford (B: 3/8 Zebu and 5/8 H) steers were finished on: D1) rangeland plus corn grain (1% of live weight) (H n=15, B n=15); and D2) high quality pasture (H n=15, B n=15) to study the effect of diet, temperament and lairage time on carcass and meat quality. Steers were slaughtered the same day in two groups, spending 15 and 3h in pens, respectively (50% from D1, 50% from D2 in each group). Animals from D1 had better carcass performance without effect of the diet on meat quality. Regardless of breed, calmer steers showed higher average daily gain and lower shear force values. Carcasses from animals in the long lairage group had a better rate of pH decline and more tender meat, suggesting that more than 3h preslaughter time should be necessary to rest and recover, mainly depending on lairage conditions.

Abstract
The experiment was designed to evaluate the effects of housing system and short-term transportation on the pituitary and adrenal response and on blood progesterone concentrations of beef cattle. Since the use of steroid hormones in farm animals has been banned in the EU (Council Directive 96/22/EC), it seems important to study the possible modifications in serum progesterone concentrations induced by stress in cattle. Thirty-two, 6 months old male Piedmontese beef cattle (16 reared in a littered loose house, Group A, and 16 housed in a littered tying stall barn, Group B) were blood sampled at T1 (6 months old), T2 (12 months old), T3 (18 months old, before transportation to the slaughterhouse) and T4 (after transportation to the slaughterhouse) in order to measure hormonal concentrations and lymphocyte glucocorticoid (GR) and β-adrenergic (β-AR) receptor concentrations. Circulating hormone concentrations were measured using commercial radioimmunoassay kits, whereas lymphocyte receptor density was determined through binding assays. In beef cattle housed in tie stall barn a significant increase in serum cortisol concentration was observed at T3, whereas there was no effect of the housing system on blood progesterone concentrations. Short-term transportation caused a significant increase in blood cortisol and catecholamine concentrations in both groups, whereas lymphocyte GR and β-AR significantly decreased in Group A. Our data confirm the activation of the hypothalamic-pituitary-adrenal axis and the catecholaminergic system in short-term transportation and suggest that the stress-induced increase in circulating progesterone concentrations does not exceed the limit established by pending legislation.

Abstract
The effects of different loading methods on the welfare, carcass characteristics and meat quality traits of hybrid commercial rabbits were investigated. 384 male rabbits, 82 days old, were transported from the farm to the slaughterhouse. At the farm, 192 rabbits were loaded onto the truck smoothly (S) and 192 rabbits were loaded roughly (R). The S loading method consisted of carefully placing each rabbit into the transport crates. In the R method, the loading was hurriedly and carelessly executed by the transport operator, throwing each animal into the crates fixed on the truck. Live weight before and after transport as well as slaughter data were recorded for each rabbit, and a subset of 80 carcasses were evaluated for meat quality. Blood samples from 80 rabbits were analysed for haematological and biochemical parameters. A significant neutrophilia (P<0.001), lymphocytopaenia (P<0.001) and an increase in serum aspartate aminotransferase (AST) (P<0.01), alanine aminotransferase (ALT) (P<0.001) and creatine kinase (CK) activities (P<0.001) were recorded in all rabbits after transport, independent of the loading method. A twofold increase in serum corticosterone concentration (6.23 vs. 14.88 ng/mL; P=0.001) was observed in all rabbits following transport. Results suggest that the stress parameters analysed were more influenced by transport and handling itself rather than by the different loading methods. The results showed that there was no adverse effect of loading method on carcass traits. Furthermore, the stress condition evidenced by haematological and biochemical parameters prior to slaughter did not affect meat quality.

Abstract
Transfer to slaughter may be very stressful for cattle and negatively affect their ultimate carcass pH. A potential link between farmers' attitudes, farmers' behaviour, responses of animals to handling and carcass pH in beef bull production was questioned. Whether carcass pH depends on experiences in handling and social mixing was analysed. We conducted a survey on commercial farms where we questioned farmers on their work and beliefs about bulls. Farmers' behaviour with bulls during a test and bulls' behaviour during loading in the truck for transport to the slaughterhouse were observed. The ultimate carcass pH was measured. Farmers tended to behave more gently with their bulls when they had positive attitudes towards gentle contacts with bulls (P = 0.07). The loading of bulls in the truck tended to be more difficult when the farmer was more ready to approach his bulls (P = 0.07). Carcass pH was higher for bulls that had not been transferred from a breeding to a finishing unit (P = 0.03). It tended to be higher when the farmer did not display a gentle behaviour (P = 0.09). The link between farmers' attitudes and farmers' behaviour and the lower meat pH resulting from a gentle farmers' behaviour during finishing are consistent with previous findings in pig, veal or dairy productions. However, the present links were weaker than in the other productions, probably due to the low frequency of close contacts between farmers and beef bulls. When loading bulls into a truck, handlers use the tendency of animals to avoid people, hence overly positive behaviour with the animals during finishing may result in more difficulties at loading. In that case, use of alternative driving aids should be recommended. Our results on carcass pH suggest some habituation to transport among bulls transferred between breeding and finishing, even though the two experiences are several months apart. In view of our results, it seems that contacts with bulls, when they are needed, should be gentle.
