The Effect of Yeast and Roughage Concentrate Ratio on Ruminal pH and Protozoal Population in Thai Native Beef Cattle 收藏

酵母和粗糙浓度比对泰国本地牛肉瘤胃pH和原生动物种群的影响
摘要
Simple Summary As a result of the recent ban on antibiotics in feed, animal probiotics are becoming increasingly popular. Yeast is extensively used as both a probiotic and prebiotic in the gastrointestinal tracts of ruminants. The purpose of this study is to determine how adding yeast (Saccharomyces cerevisiae) to the diet and changing the roughage-to-concentrate ratio (R:C ratio) affects nutrient consumption, rumen fermentation, microbial protein synthesis, and protozoal population in Thai native beef cattle. The roughage source was urea–calcium-hydroxide-treated rice straw. The findings suggest that supplementing with a R:C ratio of 40:60 and a LY of 4 g/hd/d boosted nutrient digestibility, volatile fatty acid (VFA) production, propionic acid (C3) in particular, and microbial protein synthesis while lowering protozoal population.

由于最近禁止饲料中的抗生素,动物益生菌越来越流行。酵母在反刍动物的胃肠道中广泛用作益生菌和益生元。这项研究的目的是确定在饮食中添加酵母(酿酒酵母),并改变粗糙度与浓度的比率(R:C比)会影响营养消耗,瘤胃发酵,微生物蛋白质合成和泰国本地人群肉用牛。粗糙源是尿素 - 钙氧化的稻草。调查结果表明,补充40:60的R:C比率为4 g/hd/d的LY增强营养消化率,挥发性脂肪酸(VFA)的产生,丙酸(C 3),以及微生物蛋白质的合成同时降低原生动物人群。
