摘要

Urea–lime-treated rice straw fed to Thai native beef cattle was supplemented with dry yeast (DY) (Saccharomyces cerevisiae) to assess total feed intake, nutrient digestibility, rumen microorganisms, and methane (CH4) production. Sixteen Thai native beef cattle at 115 ± 10 kg live weight were divided into four groups that received DY supplementation at 0, 1, 2, and 3 g/hd/d using a randomized completely block design. All animals were fed concentrate mixture at 0.5% of body weight, with urea–lime-treated rice straw fed ad libitum. Supplementation with DY enhanced total feed intake and digestibility of neutral detergent fiber and acid detergent fiber (p < 0.05), but dry matter, organic matter and crude protein were similar among treatments (p > 0.05). Total volatile fatty acid (VFA) and propionic acid (C3) increased (p < 0.05) with 3 g/hd/d DY supplementation, while acetic acid (C2) and butyric acid (C4) decreased. Protozoal population and CH4 production in the rumen decreased as DY increased (p < 0.05). Populations of F. succinogenes and R. flavefaciens increased (p < 0.05), whereas methanogen population decreased with DY addition at 3 g/hd/d, while R. albus was stable (p > 0.05) throughout the treatments. Thus, addition of DY to cattle feed increased feed intake, rumen fermentation, and cellulolytic bacterial populations.

尿素 - 石灰处理的稻草送入泰国天然肉牛牛，补充了干酵母（Dy）（酿酒酵母）（酿酒酵母），以评估总饲料摄入量，营养消化率，瘤胃微生物和甲烷（CH4）的生产。在115±10公斤的泰国本地肉牛的十六块本地牛粪被分成四组，使用随机完全块设计接受0,1,2和3 G / HD / D的Dy补充。所有动物均以0.5％体重的浓缩混合物，用尿素 - 石灰处理的稻草饲喂AD自由。用染料补充剂增强了中性洗涤剂纤维和酸性洗涤剂纤维的总进料摄入和消化率（P <0.05），但处理中干物质，有机物和粗蛋白质相似（P> 0.05）。总挥发性脂肪酸（VFA）和丙酸（C3）增加（P <0.05），补充剂3g / hd / d Dy补充，而乙酸（C2）和丁酸（C4）降低。随着Dy的增加，瘤胃中的原生生物群和CH4产量减少（P <0.05）。 F.琥珀酸和R.Flavefaciens的群体增加（P <0.05），而在3g / hd / d下添加甲基甲基群，而在整个处理中，r.balus稳定（p> 0.05）。因此，添加牛饲料增加的饲料摄入，瘤胃发酵和纤维素分解细菌种群。
