试验旨在研究复合添加剂对围产期奶牛生产性能的影响。试验按照年龄、胎次、体重、产犊时间接近的的原则,选择健康的围产前期中国荷斯坦奶牛16头,随机分为两组,分别为对照组和试验组。试验组奶牛每天按照精料量的1.0%添加复合添加剂,对照组不添加;试验期40 d,包括10 d预试期。结果表明:在奶牛产后的第10天,试验组奶牛产奶量比对照组高7.18 kg（P

This study was to investigate the effects of compound additive on production performance of perinatal dairy cows.16 perinatal dairy cows with similar age, weight and calving date were divided into 2 groups randomly （n=8）, one was the control group （basal diet）, and the other was the treatment group （basal diet plus 1.0% compound additive）, the experiment lasted for 40 days, including 10 days pre-experiment. Feed intake, milk yields, milk compositions （fat, protein, and lactose ）and breast health condition were measured. The results show...
