摘要: 热应激通过多种途径影响泌乳牛的产奶性能,包括减少采食量、转变能量代谢模式、激活免疫系统及引起炎症、影响乳腺发育及功能等。牧场对于热应激的应对措施通常从营养、管理、遗传三方面入手,调控效果有限。了解热应激导致泌乳牛产奶量下降的潜在机制,对于减少热应激引起的产奶损失十分重要。综述了热应激对泌乳牛产奶性能影响机制的研究进展,以期为奶牛生产中科学制定热应激缓解措施提供参考。

Abstract: Heat stress affects the milking performance of lactating dairy cows through various routes, such as reducing feed intake, altering energy metabolism pattern, activating immune system and causing inflammation, and influencing mammary gland development and function. Alleviating measures against heat stress in dairy farms are usually taken from the aspects of nutrition, management and genetics, while the effect is limited. Understanding the potential mechanisms by which heat stress causes reduction in milk production in lactating dairy cows is crucial for controlling milk production losses resulted from heat stress. This paper reviewed the research progress on the influence mechanisms of heat stress on the milking performance of lactating dairy cows, in hoping to provide references for the scientific formulation of heat stress alleviating measures in dairy cow production.

Key words: lactating dairy cow, heat stress, milking performance, mechanism
