| Abstract: | 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. |
