摘　　要：[方法]为了对比全株玉米青贮饲料与甜高粱青贮饲料饲喂奶牛的效果,选用16头中国荷斯坦奶牛为试验对象,随机分为2组,开展对比试验。[结果]结果表明,2组奶牛日粮营养水平基本一致,试验组饲喂全株玉米青贮饲料、对照组饲喂等量的甜高粱青贮饲料,试验60 d。结果表明,试验组日平均产奶量较对照组多3.27 kg,效果显著,平均每日每头均增加纯收入10.5元,经济效益显著。[结论]这表明全株玉米青贮饲料饲喂奶牛效果优于甜高粱青贮饲料。[Method] In order to compare the effect of whole-plant corn silage and sweet sorghum silage on dairy cows, 16 Chinese Holstein cows were randomly divided into two groups to carry out a comparative experiment.[Result] The results showed, the dietary nutritional levels of the two groups were basically the same. The experimental group was fed with whole corn silage and the control group was fed with the same amount of sweet sorghum silage for 60 days. The results showed that the average daily milk yield of the experimental group was 3.27 kg more than that of the control group. The effect was remarkable. The average daily net income per head increased by 10.5 yuan, and the economic benefit was remarkable.[Conclusion] The results showed that the cows feeding effect of whole plant corn silage was better than that of sweet sorghum silage.
