Heat stress and cold stress have a negative influence on cattle welfare and productivity. There have been some studies investigating the influence of cold stress on cattle, however the emphasis within this review is the influence of heat stress on cattle. The impact of hot weather on cattle is of increasing importance due to the changing global environment. Heat stress is a worldwide phenomenon that is associated with reduced animal productivity and welfare, particularly during the summer months. Animal responses to their thermal environment are extremely varied, however, it is clear that the thermal environment influences the health, productivity, and welfare of cattle. Whilst knowledge continues to be developed, managing livestock to reduce the negative impact of hot climatic conditions remains somewhat challenging. This review provides an overview of the impact of heat stress on production and reproduction in bovines.
热应激和冷应激都会对奶牛的福利和生产性能产生负面影响。已有一些研究探讨了冷应激对奶牛的影响，但本综述的重点是热应激对奶牛的影响。由于全球环境的变化，炎热天气对奶牛的影响日益重要。热应激是一种全球性现象，与动物生产性能和福利下降有关，尤其是在夏季。动物对热环境的反应极为多样，然而，热环境显然会影响奶牛的健康、生产性能和福利。尽管相关知识仍在不断发展，但管理家畜以减少炎热气候条件的负面影响仍颇具挑战性。本综述概述了热应激对牛的生产和繁殖的影响。
