摘  要：
用不同添加剂量的“增奶灵”饲喂36头泌乳中期的荷斯坦奶牛,其中对照组12头,试验A组、B组和C组各8头。试验各组牛在基础日粮中分别添加占精料量的0.05%、0.1%和0.15%的“增奶灵”,经47天的饲喂试验,结果发现,和对照组比,试验A组产奶量增加了0.45%,试验B组增加0.70%,试验C组增加1.36%;乳汁中体细胞数显著(P<0.05)下降;各组受试牛的乳脂率没有变化;此外,试验组牛蹄的质量明显改善。

摘  要：
Thirty six cows in their mid-period of milking were selected and divided into control group and experimental groups(group A?B and C) according to their age,milk production and the date of parturition.The cows in the experimental group A,B and C were added additional 0.05%,0.1% and 0.15% Zengnailing in their basal ration.The milk production,milk fat and milk somatic cells were recorded during the experiment.The results showed that the average daily milk production of experimental groups were enhanced by 0.45%(group A),0.70%(group B)and 1.36%(group C)as compared to the control group.The milk somatic cell decreased significantly in the experimental group of cows compared to the control group.However,there was no change in the average percentage of milk fat among the groups.
