摘要本试验选用3头装有永久性瘤胃瘘管和十二指肠瘘管的荷斯坦牛,分4个阶段,分别饲喂日粮Ⅰ(基础日粮+保护性赖氨酸Ⅰ30g/d)、日粮Ⅱ(基础日粮+保护性赖氨酸Ⅱ30g/d)、日粮Ⅲ(基础日粮+保护性赖氨酸Ⅲ30g/d)和日粮Ⅳ(基础日粮),研究以不同比例棕榈油脂肪粉包被的赖氨酸对瘤胃液挥发性脂肪酸和菌体蛋白的影响。结果表明,添加瘤胃保护性赖氨酸对瘤胃液挥发性脂肪酸和菌体蛋白均无明显影响(P>0.05)。瘤胃保护性氨基酸没有改变瘤胃内环境,不影响瘤胃微生物的生长和菌体蛋白的合成。 The research studied the effects of different rumen-protected lysine on rumen volatile fatty acid and bacterium crude protein of dairy cows.Three Holstein cows with permanent rumen and duodenum canula were fed with the diets with different rumen-protected lysine.The result showed that rumen-protected lysine had no significant difference on rumen volatile fatty acid and bacterium crude protein（P0.05）.The rumen-protected amino acid had no effect on the rumen environment.
