While water buffalo pass through the slaughter corridor, both the behaviors of the animals and the handling actions of the stockpersons were video recorded. Genotype had no significant influence on the scores for animal behaviors (AWBEH) and stockperson actions (AWACT). There were significant differences in carcass weight among the genotypes (p < 0.001), with the genotypes ranked from smallest to largest in carcass weight as follows: Anatolian, crossbred (F1), and Italian water buffaloes. Additionally, the EUROP fatness score was higher in carcasses from the Italian genotype compared to the Anatolian water buffaloes. Mean pH24h was lower in Italian water buffaloes than Anatolian ones. On the other hand, fat and meat color variables were not influenced by animal genotype. In conclusion, crossbreeding between Italian and Anatolian water buffaloes may increase carcass weight in crossbred (F1) genotype without altering meat quality or temperament.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/asj.70042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of the extracts on the physicochemical, textural, and sensory attributes of the sausages was evaluated using both reduced doses of nitrite and a nitrite-free preparation. The results revealed that incorporating PFE resulted in a sixfold and twofold enhancement in total phenolic content and antioxidant activity, respectively. The DPPH radical scavenging activity in sausages produced with ethanol-based PFE was more than twice as high as in sausages treated with sodium nitrite. Additionally, the combination of low-dose nitrite with PFE showed a reduction in TBARS values, leading to the prevention of lipid oxidation. Sausages with PFE exhibited lower pH and redness values, while maintaining similar aroma and odor characteristics as the controls. Although there was a slight negative impact on texture, color, and overall acceptability, PFE can be considered a potential alternative for improving bioactive content and oxidative stability of low-nitrite chicken sausages. The application of PFE could offer a promising opportunity to enhance the nutritional profile and quality attributes of processed meat products.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/asj.70039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rich in carbohydrates, protein, fat, and various bioactive compounds, it offers significant growth and health benefits. It is commonly used as a replacement for cereals and grains as an energy source in the diet. However, its potential as animal feed is constrained by antinutritional factors and susceptibility to rancidity due to lipase activity. Recently, there has been a growing interest in fermentation to enhance rice bran's nutritional profile. It has been confirmed that fermenting rice bran could increase the proportion of crude protein and fat. Moreover, feeding fermented rice bran (FRB) improves the growth performance of food-producing animals by increasing efficiency. These results, along with their beneficial effect on gut microbiota, may improve the overall health of food animals. In this review, we aimed to summarize the latest research on the fermentation of rice bran, focusing on the role of microorganisms and the factors influencing the quality and nutritional value of FRB. Additionally, we will explore the impact of FRB on nutrient composition and animal performance, highlighting its potential as a valuable feed ingredient.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/asj.70037","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MAC-T cells were pretreated with UDCA at 25, 50, and 100 μM before exposure to PA at 300 μM. UDCA was noncytotoxic at these concentrations and significantly improved cell viability, which was reduced by PA. UDCA pretreatment notably decreased PA-induced expression of GRP78, XBP1s, ATF4, and CHOP mRNA, indicating reduced ER stress. Moreover, UDCA substantially lowered PA-induced reactive oxygen species production and dichlorofluorescein fluorescence intensities. Although PA treatment elevated GSSG levels and disrupted redox balance by decreasing both the total GSH/GSSG and reduced GSH/GSSG ratios, UDCA effectively counteracted these effects. Specifically, UDCA reduced PA-induced GSSG levels and restored redox balance by increasing both total and reduced GSH/GSSG ratios. These findings suggest that UDCA mitigates PA-induced apoptosis in MAC-T cells by enhancing redox homeostasis. Therefore, incorporating UDCA into dairy cow feed could help reduce PA-induced cellular stress and improve milk production during periods of negative energy balance.","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/asj.70038","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143380378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cultivation with curcumin of NVF COCs significantly improved the proliferative activity of cumulus cells.
