| 摘 要： | 试验选择24头经产泌乳末期荷斯坦奶牛,采用完全随机试验设计,分为试验组和对照组,试验组奶牛饲喂裹包全混合日粮,对照组采用常规精粗分开饲喂方式进行饲喂,旨在研究裹包TMR对泌乳末期奶牛生产性能及消化特性的影响。结果表明,试验组奶牛的产奶量、4%标准乳、饲料效率、乳蛋白和乳糖产量显著高于对照组(P<0.05),干物质采食量、乳成分含量和体细胞计数试验组与对照组差异不显著(P>0.05)。试验组日粮中粗蛋白和粗脂肪的表观消化率显著高于对照组(P<0.01),其他日粮养分的表观消化率在两处理组间差异不显著(P>0.05)。采用裹包TMR饲喂奶牛,与精粗分开饲喂方式相比,可提高奶牛的产奶性能和日粮养分表观消化率。 |

| Abstract: | The objective ofthis experiment was to study the effect ofbaled totalmixed ration on per-for-mance and digestive characteristics of late lactation dairy cows. Total twenty-four multiparous Holstein cows were used in a complete randomized design and divided into treatment and controlgroups, respectively. Animals were offered baled total mixed ration and forge and concentrated separately for treatment and control groups, respectively. The results showed that consumption ofbaled totalmixed ration increased cow... |
