试验旨在研究一种复合添加剂对高产奶牛生产性能的影响。根据产奶量、胎次、体重等相近的原则选择4f）头中国荷斯坦牛，随机分成4个处理组，即对照组、试验Ⅰ组、试验Ⅱ组、试验Ⅲ组，对照组饲喂基础日粮，试验Ⅰ、Ⅱ、Ⅲ组在此基础上，分别按每头牛每天精料量的0．5％、0．8％、1.0％添加复合饲料添加剂。、试验期45d，其中预试期10d，正试期35d，测定产奶量、乳成分等指标。结果表明，在高产奶牛日粮中添加复合添加剂对乳成分基本无影响，但可显著提高奶牛产奶量，结合成本考虑，以精料的0．5％添加量效果最好、

A feeding trial was conducted to investigate the effects of a compound additive on the production performance of high producing dairy cows. A total of 40 high producing dairy cows with similar age, weight and calving date were divided into 4 groups randomly（n=10）and were assigned to one of the four diets： basal diet or basal diet supplemented with 0.5%,0.8% or 1.0% compound additive, the feeding trial lasted for 45 days, including 10 days of pre-experiment. Feed intake, milk yields, milk compositions （fat, protein, and lactose and s somatic...
