摘　　要：荷斯坦种公牛培育作为奶牛繁育体系中重要环节,承担着为牧场提供优秀冻精、扩繁高产奶牛、推进奶牛群体改良计划的重要任务。然而夏季热应激导致的种公牛繁殖性能下降等功能障碍大大影响着种公牛的正常生产。文章对近年来国内外不同课题组在种公牛热应激问题上的研究成果予以归纳整理,对营养调控水平和遗传选育水平上缓解热应激的最新研究进展进行综述,以期为夏季种公牛高效生产提供必要的科学依据。The cultivation of Holstein breed bulls as an important part of the breeding system of dairy cows, undertakes the important tasks of providing the excellent frozen semen, propagating high - yielding dairy cows and promoting the dairy herd improvement plan. However, the heat stress in summer causes the dysfunction of dairy cows, especially the decrease of reproductive performance of dairy cows, which greatly affects the normal production of the breed bulls. This paper generalizes and collates the research findings in recent years on the problem of heat stress from the domestic and international different research groups, and reviews the newest research progress on relieving the heat stress at the levels of nutrient regulation and genetic breeding, with a view to providing necessary scientific basis for high- effectiveness production of the breed bulls in summer.
