| 摘 要： | 将20头安装瘤胃瘘管的荷斯坦产奶牛随机分为对照组和试验Ⅰ～Ⅲ组，每组5头，对照组饲喂TMR，试验Ⅰ～Ⅲ组饲喂TMR分别加150．0g／（头·d）复合脂肪酸、乳酸和复合脂肪酸＋乳酸（1：1），探讨复合脂肪酸和乳酸对奶牛瘤胃CH4释放量、VFA和NH3-N浓度及产奶性能的影响。结果显示，TMR加150．0g／（头·d）复合脂肪酸＋2L酸（1：1），使奶牛瘤胃NH3-N和CH4释放量分别减少11．92％（P〈0．05）和21.35％（P〈0．01），FCM、乳脂率和乳糖含量分别提高3．28％、5．12％和3．62％，瘤胃VFA明显增加，能够有效抑制奶牛对空气的CH4污染．显著提高奶牛的生态效益和经济效益。

| Abstract: | Twenty Holstein sows fitted with ruminal cannulas were divided into control and treatment Ⅰ～ⅢI groups at random with 5 cows of each group, which were fed on TMR（control） and TMR added 150.0g/（h-d） compound fatty acid, lactic acid, compound fatty acid and lactic acid（l：l） respectively（ Ⅰ～Ⅲ treatments）. The objective was to study the effects of compound fatty acid and lactic acid on rumen VFA, NH3-N concentration, CH4 production and milk performance of Holsteins. The results showed that, for Holstein cows which were fed on 150.0g/（h·d） compound fatty acid and lactic acid （1：1）, the rumen NH3-N concentration and CH4 production reduced 11.92% （P〈0.05）and 21.35% （P〈0.01）respectively. The FCM, milk fat percentage and lactose enhanced 3.28%, 5.12% and 3.62% respectively. The rumen VFA concentration increased significantly, which inhibited the air pollution of CH4 energy and enhanced the dairy ecological and economic benefit significantly. |
