摘　　要：该研究旨在探究不同饲养方式(放牧+补饲、舍饲)对三河牛生产性能、繁殖性能的影响。选取40头体重接近、年龄、胎次一致,已经妊娠5个月的三河牛母牛为试验动物,随机分为2组,分别为对照组和试验组。对照组的牛的饲养方式为放牧+补饲,试验组的牛的饲养方式为舍饲。经过为期5个月的饲养之后,测定奶牛的生产性能指标以及繁殖性能指标。结果显示,与对照组相比,试验组的三河牛的产奶量、乳脂率、乳蛋白率等生产指标均有所提高,且繁殖性能也显著优于对照组。在三河牛饲养过程中为保持较高的产奶性能和良好的繁殖性能需要以舍饲的方式进行饲养。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.
