Vet World 2024; 17:1149-1156. [PMID: 38911096 PMCID: PMC11188889 DOI: 10.14202/vetworld.2024.1149-1156] [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: 02/15/2024] [Accepted: 04/29/2024] [Indexed: 06/25/2024] Open
Abstract
Background and Aim Feeding by-products, such as pomegranate seed pulp (PSP) and coconut meal (COC), to livestock may enhance production efficiency and increase profits. This study aimed to evaluate the effects of PSP and COC on milk production, body weight change, metabolic response (Exp. 1), digestibility, and N balance (Exp. 2). Materials and Methods Twenty-four ewes nursing single lambs were randomly assigned to one of three diets: Control (CON) (n = 8), 7.5% PSP (n = 8), and 7.5% COC (n = 8) of dry matter (DM). Every sheep was born 3-4 days before the start of the experiment. The 1st week of the experiment was devoted to diet adaptation, while the data were collected during the following 8 weeks (Exp. 1). Nine lambs were randomly assigned to one of the three diets for intensive data collection to evaluate the diet digestibility and animal nitrogen (N) balance (Exp. 2). The data were analyzed using the MIXED SAS procedures. Results The PSP group consumed more DM, followed by the COC and CON groups. For lambs, the final BW, total gain, and average daily gain in the PSP group were greater (p < 0.05) than those in the COC and CON groups. The CON group had lower milk output, total solids, protein, fat, and lactose levels than the PSP and COC groups (p < 0.05). The cost of milk production was lower (p < 0.05) in the PSP and COC diet groups than in the CON group. Blood serum parameters were similar among the dietary groups, except for total cholesterol and high-density lipoprotein, which were higher in the COC group than in the CON group. No differences were observed in nutrient digestibility and N balance. Conclusion Feeding PSP and COC to nursing ewes appears beneficial because it increases milk production and pre-weaning lamb growth and reduces milk production cost.

Abstract
Successful breeding depends on feeding. The present study aims to evaluate the Carica papaya seed effect on the growth performance of rabbits. The zootechnical parameters studied are weight growth, average daily gain, Feed Conversion Ratio, and carcass characteristics of kits. The experiment was conducted on 48 rabbits, divided into 4 groups, for 6 weeks. Forty-eight rabbits were divided into four (04) groups of 3 repetitions of 4 rabbits. The animals were fed diets containing various levels of papaya seed powder at variable contents: 0% (group T0), 4% (group T1), 6% (group T2), and 8% (group T3). At the end of the experiment, three animals were slaughtered in each animal group to assess the quality of the carcasses and organs. 6% of the seeds of Carica papaya significantly improved (p < 0.05) the average daily gain of the kits: T2 (22.40 g / d) compared to the T0 group (11.32 g / d), T1 (12.20 g / d) and T3 (17.53 g / d). The best Feed Conversion Ratio (0.80) was recorded in the animals of group T2. In contrast, the highest carcass yield was recorded in the rabbits of group T3 (62.70%). In conclusion, 6% was optimal in the feed rations of fattened rabbits to improve production performance. Breeders can consider the benefits of introducing Carica papaya seeds into the rabbits' diet.

Abstract
Background and Aim The use of alternative feeds in feeding livestock as an alternative to traditional feeds has been used for many years, on the one hand, to lower the price of feed and, on the other hand, to raise the profitability of raising livestock. The study aimed to investigate the effect of feeding pomegranate seed pulp (PSP) on the growth performance and carcass characteristics and the health of Awassi lambs. Materials and Methods Twenty-four male lambs (16.9 ± 0.42 kg) were assigned randomly to one of two isonitrogenous (160 g/kg crude protein of dietary dry matter [DM]) treatment diets. The diets were the control (CON) and PSP-containing diet (100 g/kg of dietary DM; PSP100). The experimental period was 70 days preceded by 7 days of adaptation to diets. Feed intake was measured and lambs were weighed on day one and then biweekly. On day 49, eight lambs (four lambs per treatment) were chosen randomly and placed in metabolic cages for a digestibility trial. At the end of the trial, lambs were slaughtered to evaluate carcass characteristics and meat quality. The data were analyzed using Proc Mixed procedures of SAS. Results The results revealed that nutrient intake was greater (p < 0.05) in lambs fed PSP100 than those fed the CON diet. Nitrogen intake and nitrogen retention were greater (p < 0.05) for lambs who consumed the PSP100 diet compared to CON. Final weight, total gain, and average daily gain were greater (p < 0.05) with lambs fed PSP100. Hot and cold carcass weights were higher (p < 0.05) by the PSP100 group than by the CON group. Carcass cut weight increased (p < 0.05) with feeding PSP100 diet. No differences were detected in blood parameters except high-density lipoprotein content, which was greater (p < 0.05) in the PSP100 group compared with the CON group. Conclusion It could be concluded that adding PSP to lambs' diets improved growth and carcass measurements positively and did not negatively affect lambs' health; therefore, it is recommended to use PSP as an alternative to traditional feeds in lambs formulated rations.

J Anim Sci 2023; 101:skad232. [PMID: 37422771 PMCID: PMC10612130 DOI: 10.1093/jas/skad232] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Accepted: 07/07/2023] [Indexed: 07/11/2023] Open
Abstract
This study aimed to investigate the effects of ellagic acid (EA) supplementation on body weight (BW), nutrient digestibility, fecal microbiota, blood biochemical indices, and urolithin A metabolism in 1-yr-old Thoroughbred horses. A group of 18 1-yr-old Thoroughbred horses, with an average weight of 339.00 ± 30.11 kg, were randomly allocated into three groups of six horses each (three males and three females). The control group (n = 6) received only the basal diet, whereas test groups I (n = 6) and II (n = 6) were fed the basal diet supplemented with 15 mg/kg BW/d and 30 mg/kg BW/d of EA, respectively, for 40-d. The results showed that test group I and II horses had a significant increase in total weight gain by 49.47% and 62.74%, respectively, compared to the control group. The digestibility of various components in the diets of the test group horses was improved, including dry matter, organic matter, gross energy, neutral detergent fiber, acid detergent fiber, and calcium. Additionally, the digestibility of crude protein and phosphorus (P) in test group II horses increased significantly by 10.96% and 33.56% (P < 0.05), respectively. Moreover, EA supplementation significantly increased the fecal abundance of Firmicutes, Bacteroidetes (P < 0.05), Fibrobacterota, p-251-o5, Desemzia incerta (P < 0.05), and Fibrobacter sp. (P < 0.05), while reducing the abundance of Proteobacteria, Pseudomonadaceae, Pseudomonas, and Cupriavidus pauculus (P < 0.05 or P < 0.01). Fecal samples from test group II showed 89.47%, 100%, and 86.15% increases in the concentrations of acetic acid, valeric acid, and total volatile fatty acids, respectively. In addition, the plasma levels of total protein, and globulin increased significantly in test groups I (7.88% and 11.35%, respectively) and II (13.44% and 16.07%, respectively) compared to those in the control group (P < 0.05). The concentration of urolithin A in fecal and urine samples was positively correlated with increasing doses of EA. These findings suggest that supplemental feeding of EA improved nutrient digestibility, blood biochemical indices, and fecal microbiota in 1-yr-old Thoroughbred horses, promoting growth and development.

Abstract
Four hundred and eighty 1-day-old Japanese quail chicks from white and brown strains, 240 birds from each strain, were divided into 4 treatment groups with 6 replicates each (10 birds/replicate). Both strains of quail were fed diets containing 0%, 3%, 6%, and 9% pomegranate peel (PP) powder for a period of 42 days. Results revealed that the final body weight (BW), total feed intake (TFI), body weight gain (BWG), gizzard percentage, and eviscerated carcass weight of white growing quails were significantly (P < 0.05) higher than the brown strain. Quail group fed with 6% PP powder had the highest (P < 0.001) average final BW and BWG (P < 0.001). The dietary PP powder at different levels significantly (P = 0.032) decreased TFI, but had no significant effect on carcass traits except for the liver percentage. Quails fed diet 3% and 9% PP powder had significant (P < 0.001) increased count of immune cells, and improved antioxidant potency. White quails fed diet 3% and 6% PP powder had greater expression of hepatic GHR gene. The expression of hepatic IGF-1 gene was significantly (P < 0.05) higher for brown quails fed diet 6% and 9% PP powder. White quails recorded the highest value of total return (TR). Quails fed diet 6% and 9% PP powder significantly (P < 0.001) recorded higher net return (NR) values. In conclusion, dietary inclusion of PP powder at levels up to 9% for Japanese quail strains improved the growth performance, increased antioxidant properties, enhanced hepatic gene expression, and did not show any adverse influence on carcass quality and blood indices of Japanese quail. Moreover, it increased the NR.

Prevalence, Characterization, and Pathogenicity of Salmonella enterica Subspecies enterica Serovar Derby from Yaks in the Aba Tibetan Autonomous Prefecture, China. Animals (Basel) 2021; 11:ani11082397. [PMID: 34438854 PMCID: PMC8388676 DOI: 10.3390/ani11082397] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Revised: 08/07/2021] [Accepted: 08/09/2021] [Indexed: 11/30/2022] Open
Abstract
Simple Summary Salmonella spp. is a very important pathogen in the livestock industry and public health, which poses a major threat to global public health. Yaks and their by-products have a significant economic status in the Qinghai–Tibetan Plateau. The aim of this study was to investigate the prevalence of salmonella in yak farms and to conduct a molecular characterization and tests on its pathogenicity in mice with the use of salmonella isolated from yaks with diarrhea as well as from drinking water samples. The prevalence of salmonella was 19.75% of 162 samples collected from yak farms, and all isolates were found to belong to the serovar of Salmonella Derby and ST40. All Salmonella Derby isolates from both fecal and drinking water samples from 13 farms were clonally related based on SNP alignment. Salmonella Derby was still detected positively in the feces of model mice on day 24 post-injection. This study reports the prevalence of Salmonella Derby in yaks with diarrhea and in their drinking water. In addition, the pathogenicity of the S. Derby in mice was investigated. Findings suggest that Salmonella Derby excreted by diarrheic yaks is a source of contamination for other yaks and the environment and is highly pathogenic to mice. Seeing that Salmonella Derby has become one of the most common Salmonella serovars, this situation gives rise to further risk from the potential spread of food-borne diseases. Abstract Salmonella enterica subsp. enterica serovar Derby (S. Derby) is one of the numerous non-typhoidal Salmonella serovars and has been recognized as a food-borne pathogen. In 2019, outbreaks of salmonellosis were reported in 13 yak farms in the Aba Tibetan Autonomous Prefecture, China. A total of 32 salmonella strains were isolated from 162 fecal samples of yaks with diarrhea as well as from drinking water samples. The isolates were subjected to serovar identification, animal experiments, and whole-genome sequencing (WGS) analyses. The serovar of all the isolates was S. Derby, and the sequence types (STs) were ST40. The analysis of the differences of single-nucleotide polymorphisms (SNPs) showed that the salmonella strains isolated from 13 farms were clonally related. Animal experiments showed that the lethal dose (LD50) was 4.57 × 107 CFU (colony-forming units); the shedding time of S. Derby in mice was 24 days; the bacterial loads in spleen were higher than those in other organs (ileum, liver, and cecum). Pathological analyses by hematoxylin and eosin (H&E) staining revealed obvious damage in the spleen, liver, and intestine. These results indicate that the S. Derby from yaks can cause infection in mice.

Abstract
The aim of this study was to evaluate antioxidant, antihyperlipidemic and hypotensive properties of pomegranate peel (PP) on antioxidant status, fat deposition, lipid peroxidation and pulmonary hypertensive response in broiler chickens. A total of 375 one‐day‐old male broilers (Cobb 500) were randomly assigned to five treatments included dietary PP levels of 0, 2.5, 5.0, 7.5 and 10 g/kg. Supplementation of PP at 7.5 and 10 g/kg resulted in significant upregulation of hepatic catalase (p < 0.004) and superoxide dismutase1 (SOD1; p < 0.05), which reflected in decreased concentration of circulatory malondialdehyde (MDA). Dietary inclusion of PP at 7.5 and 1.0 g/kg significantly decreased serum concentrations of triglycerides (p < 0.004) and cholesterol (p < 0.006) with concomitant decrease in abdominal fat deposition (p < 0.05). The antihyperlipidemic effect of PP was mediated through down‐regulation of peroxisome proliferator activated receptor alpha (PPARα). Hypotensive effect of PP was also observed at 7.5 and 10 g/kg as reduced heart weight and the right‐to‐total ventricular weight ratio (RV/TV) and decreased mortality from pulmonary hypertension. The hypotensive property of PP was associated with increased concentration of serum nitric oxide. In conclusion, this study revealed antioxidative, antihyperlipidemic and hypotensive effects of PP at 7.5 and 10 g/kg in broiler chickens exposed to hypobaric hypoxia. Health‐beneficial effects of PP suggest this product as a promising multi‐functional phytogenic feed additive for broiler chickens. In this study, evaluate antioxidant, antihyperlipidemic, and hypotensive properties of pomegranate peel (PP) on antioxidant status, fat deposition, lipid peroxidation, and pulmonary hypertensive response in broiler chickens. Supplementation of PP at 7.5 and 10 g/kg resulted in significant up‐regulation of hepatic catalase, superoxide dismutase1 and peroxisome proliferator activated receptor alpha (PPARα), which reflected in decreased concentration of circulatory malondialdehyde (MDA).

Abstract
The current experiment was designed to study the response of two strains of laying Japanese quail to diet containing different levels (0%, 3%, 6%, and 9%) of pomegranate peel (PP) powder for a period of 6 weeks, on egg production, blood chemistry, carcass traits, expression of FSHR and LH-β genes, and economic efficiency. A total of 576 6-week-old Japanese quails were made up of two strains: white quails (n=288) and brown quails (n=288). Four treatment groups were randomly distributed for each strain. Each group was subdivided into 6 replicates of 10 birds each. Results revealed that the white strain showed significant (P<0.05) higher values in final body weight (BW), egg quality parameters, weights of dressed carcass, and total return (TR) compared with the brown strain. Brown strain had higher hen day egg production % (HDEP%). A significant (P<0.05) interaction effects between genetic type and the dietary PP powder levels was recorded in growth traits, some egg production traits, and mRNA expression of FSHR and LH-β genes. Results concluded that all the dietary levels of PP powder up to 9% improved growth traits, egg production traits, fertility% (P=0.001), and hatchability% (P=0.007). Moreover, they have a safely biochemical effect on the level of urea (P=0.002) and the concentration of aspartate amino transferase (AST) (P<0.001). It also enhanced mRNA expression of FSHR and LH-β genes, but showed non-significant (P>0.05) influence on carcass traits. Economically, the net return (NR) was increased in quails fed on 6% and 9% PP powder diets.
