This study aims to explore the effects of different feeding methods(grazing+supplementary feeding,and house feeding)on the production and reproductive performance of Sanhe cattle.Forty cows of similar weight,age,and parity,who have been pregnant for 5 months,were selected as experimental animals and randomly divided into two groups:the control group and the experimental group.The feeding method of the control group's cattle is grazing+supplementary feeding,while the feeding method of the experimental group's cattle is house feeding.After a 5-month feeding period,the production performance indicators and reproductive performance indicators of the cows were measured.The results showed that compared with the control group,the production indicators of Sanhe cattle in the experimental group,such as milk yield,milk fat rate,and milk protein rate,were significantly improved,and their reproductive performance was also significantly better than that of the control group.In summary,in order to achieve high milk production performance and good reproductive performance in the process of raising Sanhe cattle,it is necessary to raise them in captivity.
