Taurine, biosynthesized from methionine or cysteine in the liver, plays a crucial regulatory role bile acid conjugation, antioxidant effects, and glucose cholesterol metabolism. This may influence metabolic changes associated with fat accumulation beef cattle. However, physiological of taurine this species has not been fully elucidated. In study, we explored Japanese Black steers (Bos taurus) different phases during fattening period. To examine correlation among plasma concentrations, various parameters, genes related to synthesis used biopsied liver tissues, blood samples, rumen fluids collected 21 at three stages, i.e., early (T1; 13 mo age), middle (T2; 20 late (T3; 28 age) phases. Additionally, investigate mechanisms underlying expression profile genes, primary bovine hepatocytes obtained 4-wk-old Holstein calves were treated palmitate, oleate, acetate, propionate, β-hydroxybutyrate (BHBA). Plasma concentrations significantly (P < 0.001) increased T2 phase, which is potentially attributable energy intake assimilation induced by concentrated feed.

Hot environments negatively affect cattle productivity, and global warming also causes heat stress, thereby adversely impacting production. Improving management under such conditions is an urgent issue. Trehalose can ameliorate volatile fatty acid production the diversity of ruminal microbiota in dairy cattle. However, no studies have evaluated on Japanese beef heifers. In this study, we investigated effects trehalose supplementation productivity Black heifers heat-stressed conditions. Six cyclic were divided into two groups: control supplemented. The microbiota, pH, these analyzed over 10 weeks summer central Japan. During experimental period, group showed significantly higher concentrations acetic propionic acids than those trehalose-supplemented (p<0.05, two-way repeated measures ANOVA). acetic/propionic ratio significant difference between groups. alpha bacterial biota supplemented was that ANOVA) along with a change beta fungal PERMANOVA). LEfSe analysis identified specific microorganisms samples: 4 13 bacteria; each one fungus; 5 protozoan families, respectively. improved especially types bacteria fungi related to carbohydrate digestion, maintained balance VFA Therefore, feed could improve global-warming scenarios.
