Abstract
Since veal production has declined in the U.S., American veal producers are currently making efforts to implement new production standards to improve product quality and animal welfare. In this study, we hypothesized that diets containing brewery grains, starch and omega-3 fatty acids could lower a blood stress indicator and improve meat quality, mostly from a nutritional value stand point. Holstein bull calves with approximately 94.67 ± 12.07 kg of body weight and two months old were randomly assigned to 1 of 3 dietary treatments. Diets were formulated with nonmedicated milk replacer, microbreweries spent grains, and a mineral mix (CONTROL); CONTROL + isolated maize starch (STARCH); and CONTROL +3% fish oil (OMEGA-3). Veal calves fed all three diets were heavier than calves of the same age from experiments reported in the existing literature. Dietary treatments did not affect carcass weights, pH, color, moisture, sensory attributes, volatile profile, and fat quality indexes. Calves fed STARCH and OMEGA-3 showed the lowest levels of blood cortisol. Veal fed CONTROL and OMEGA-3 had higher concentrations of ΣMUFA when compared with STARCH. Veal fed OMEGA-3 had the highest concentrations of EPA, DHA, and Σn-3. Veal from all treatments had very high concentrations of ΣMUFA, mostly driven by high levels of c-9 18:1 n-9 from the milk replacer. Feeding OMEGA-3 lowered blood cortisol and increased levels of EPA and DHA without harming sensory attributes. Overall, including brewery grains, starch and fish oil in liquid diets containing milk replacer can improve veal production.

Abstract
The measure of hair cortisol concentration (HCC) is becoming an emerging approach to monitor mid-/long-term stress in animals, so it is more and more important to develop accurate and reliable methods. In the light of this, the aim of the present study was to compare mane HCCs of 47 horses with different managements, by means of an immunoassay (ELISA) and liquid chromatography coupled to hybrid high-resolution mass spectrometry (LC-HRMS/MS). After the washing step, the ground hair was extracted with methanol. The extract was evaporated and redissolved in two different aqueous solutions, depending on the detection technique. The methods were validated according to EMA guideline for bioanalytical method validation, in the range 2–50 pg mg−1 (ELISA) and 1–100 pg mg−1 (LC-HRMS/MS). Satisfactory quantitative performances were obtained for both of the approaches, but this latter demonstrated better precision. The detected concentrations in real samples were encompassing the range 1.3–8.8 pg mg−1 and 2.0–17.9 pg mg−1 by means of LC-HRMS/MS and ELISA, respectively. Overall, HCCs measured with ELISA technique were 1.6 times higher. The overestimation of immunoassay results might be caused by cross-reactivity phenomena of laboratory reagents and other structurally similar hormones present in the mane.

Abstract
Background Type-4 abomasal ulcers (U4) are perforated ulcers causing diffuse peritonitis. This retrospective study describes the clinical, laboratory and ultrasonographic findings in 38 calves with U4. The medical records of 38 calves aged three days to 20 weeks with U4 were scrutinised. Results The most common clinical findings were poor general health (95%), reduced skin elasticity (95%), rumen atony (91%), abdominal guarding (76%) and positive percussion auscultation and/or swinging auscultation on the right side of the abdomen (75%). The most frequent laboratory findings were increased numbers of segmented neutrophils (87%), eosinopenia (87%), acidosis (84%), azotaemia (79%) and hyponatraemia (79%). The most frequent abdominal ultrasonographic findings were intestinal atony (68%), fluid (67%) and fibrin deposits (58%) in the abdomen. Thirty-five calves were euthanased and three calves died spontaneously. All calves underwent pathological examination. Diffuse peritonitis caused by a transmural abomasal ulcer was the principal diagnosis in all calves. Conclusions Perforated abomasal ulcers cause severe illness, and a thorough clinical examination combined with ultrasonographic abdominal examination should lead to a tentative diagnosis.

Theriogenology 2021; 175:89-94. [PMID: 34517287 DOI: 10.1016/j.theriogenology.2021.08.037] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 05/20/2021] [Accepted: 08/31/2021] [Indexed: 11/19/2022]
Abstract
Cortisol (C) and dehydroepiandrosterone (DHEA) are recognized as the main fetal steroids, and they are likely to influence fetal development and have long-term effects on newborn hypothalamic-pituitary-adrenal axis (HPA) function. DHEA is often measured as its sulfates and expressed as DHEA-S. Hair analysis represents a promising methodological approach for the non-invasive measurement of steroids, allowing for a retrospective analysis of the total exposure to steroids over time, and avoiding the influence of acute events or circadian fluctuations. Hair cortisol and DHEA concentrations have been investigated in cows, but no studies have been performed on calves. The object of this study was to evaluate hair cortisol (HC) and hair DHEA-S (HDHEA-S) concentrations in beef calves from birth to six months of age. Hair samples of 12 beef calves (seven males, five females) were firstly collected at birth (T1) and then every three weeks up to six months of age (T2-T10), collecting only the re-grown hair. HC and HDHEA-S were analyzed by radioimmunoassay (RIA). Calves sex, weight and APGAR score were registered immediately after birth. Statistical analysis revealed that both HC and HDHEA-S were influenced by sampling time (P < 0.001). HC concentrations were higher at T1 compared to all subsequent samplings (T2-T10, P < 0.01); HC concentrations were higher at T2 compared to T4-T10 (P < 0.01), while no further changes were detected from T3 onward. Higher HDHEA-S concentrations were registered at T1, T2 and T3 compared to all the other samplings (P < 0.01). No correlation was found between hair concentrations of both steroids and calf sex or birthweight. APGAR score was negatively correlated only with HC at birth (P < 0.05). These data demonstrate that C and DHEA-S are quantifiable in the hair of calves and are influenced by their age. The higher HC detected at birth (T1) probably reflects the high serum C concentrations present late in pregnancy and increased by the fetal HPA axis, by which parturition is initiated in cows. The highest HDHEA-S at birth (T1) in calves indicates that the largest amounts of DHEA and its sulfates are produced during fetal development. Moreover, the findings of higher HC at three weeks after birth and of higher HDHEA-S until six weeks after birth, suggest that C and DHEA secretion continues also beyond birth, and that these steroids could be involved in the events occurring during the challenging first weeks of age in the calf.

Abstract
Welfare of dairy cows can be assessed using welfare assessment protocols consisting of resource, management and animal-based measures. Welfare Quality® Assessment Protocol is one of the best-known protocols, which depends almost entirely on animal-based measures. To gain more objective and rapid welfare assessment, new techniques have been developed to measure welfare of animals, such as hair cortisol concentration. As cortisol is released in response to stress, it has long been used as a biomarker of stress in animals. While the precise mechanism of cortisol incorporation into hair is unknown, hair cortisol concentration seems to be a marker of long-term systemic cortisol concentration. Hair cortisol is, therefore, a potential marker of chronic stress and is not likely to be affected by acute stress. Studies on cattle show connections between hair cortisol concentration and factors such as pregnancy, parity, diseases, ectoparasites, body condition score, environmental changes, stocking density and milk yield. Hair cortisol concentration appears to be affected by time of sampling, cow age and breed, UV radiation, season, body region of sampled hair and hair colour. Its concentration also depends on sampling and analytical methods. Hair cortisol is a promising non-invasive tool to evaluate welfare of dairy cows, however, more research is needed to determine the extent of effects on its concentration and the appropriate method of sampling and analysis. Correlations between Welfare Quality® Assessment Protocol scores and pooled hair cortisol concentrations have not yet been found, and more research is needed with larger sample size, a standardized protocol of hair sampling, processing and analysis. With proper attention to detail, hair cortisol levels in pooled hair samples might come to be used as a reliable indicator of dairy animal welfare.
