| 摘 要： | 随着奶牛业产的迅速发展,如何提高饲料利用率,增加奶产量,提升牛奶品质,提高牛体健康,减少奶牛常见疾病,已经成为现代奶牛业的关键.本文简述了在奶牛日粮中添加“益佳泰”饲喂试验,选择8头泌乳期的经产中国荷斯坦奶牛,试验牛产奶量、胎次、产犊日期相近,健康无疾病.随机分为4个组,采用4×4拉丁方设计,其中一组为对照组,试验组奶牛基础日粮精料里分别添加5％,10％,15％,各组采用相同的基础日粮,观测其奶牛生产性能.结果表明,奶牛日粮中添加10％“益佳泰”能够有效的提高奶产量,但对奶品质有一定的影响.

| Abstract: | With the rapid development of dairy cattle industry, improving feed efficiency, milk yield and quality, enhancing the health of cattle and decreasing common diseases have become the key point of modern dairy cattle breeding. Eight healthy Lactating multiparous Chinese Holstein cows with similar milk yield, parity, calving date were selected and allotted into 4 groups （4 × 4 Latin Square Design）, one control group and three experimental groups fed with 5 %, 10% and 15 % Yi Jia Tai. The results showed that the group with 10% Yi Jia Tai can improve milk yield, and partly improve milk quality. |
