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.</p>","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}

In a completely randomized experiment, 12 lactating crossbred ewes (3 ± 1.5 DIM) were fed one of three isoenergetic diets with forage-to-concentrate ratio of 70:30. The three experimental diets (CON, CS1, and CS2) were formulated by replacing AH with different levels of CS (0%, 30%, and 60%, respectively). Energy balance was determined through a metabolism and respiration trial. We observed identical trends for feed intake and gross energy intake (GEI); the GEI ranged from 0.97 to 1.34 (MJ/kg BW^0.75 day) among the treatments. Around 26%–33% of the GEI was lost as feces, 56%–60% for heat production, 14%–16% for milk production, 5%–6% for methane emission, and 3% for urinary energy. The metabolizable energy requirement for maintenance of crossbred Hu ewe was estimated to be 484.7 kJ/kg body weight^0.75/day. Furthermore, the energy digestibility and metabolizability of the CS diets were significantly greater than those of the CON diet. Substituting AH for up to 60% CS increased energy utilization efficiency without detrimental effects on milk production in crossbred Hu ewes fed a forage-based diet.</p>\u0000 </div>","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":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","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.</p>","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}

Thus, it is important to develop technique to improve the quality of NVF-derived oocyte by IVM. Since it has been reported that reactive oxygen species (ROS) reduces oocyte quality, in this study, we investigated whether curcumin that is known as antioxidant could improve oocyte quality derived from NVF. As results, cultivation of NVF Cumulus-oocyte complexes (COCs) with curcumin significantly improved cumulus expansion and oocyte meiotic maturation of NVF COCs compared to those of NVF COCs without curcumin. Cultivation with curcumin of NVF COCs significantly improved the proliferative activity of cumulus cells. Furthermore, the cultivation significantly reduced ROS activity and increased mitochondrial activity. Hence, it was revealed that the addition of curcumin to the maturation medium increased mitochondrial activity and reduced ROS levels in NVF-derived cumulus cells and oocytes, thereby improving the maturation of oocytes within COCs.</p>\u0000 </div>","PeriodicalId":7890,"journal":{"name":"Animal Science Journal","volume":"96 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143112144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The responses to this dietary CP restriction were independent of sex, except the serum urea concentration and total proteins, which were only steadily reduced in intact males fed the low-CP diet.

Quantitative polymerase chain reaction analysis showed that the expression levels of representative heat and oxidative stress–related genes were significantly increased in cells cultured at high temperatures compared with those in cells cultured at basal temperatures. Moreover, luciferase reporter assays showed that the reporter activity of the heat shock element and antioxidant responsive element (ARE) was increased in cells cultured at high temperatures compared with that in cells cultured at basal temperatures. Furthermore, the stability of nuclear factor erythroid 2 like 2 (NFE2L2), a master regulator of the cellular stress response, increased under high temperatures.
