妊娠后期热应激对奶牛产前及产后阶段都有着深远的影响.除损害免疫功能外,热应激对乳腺发育有着不利影响,其残留效应还影响到泌乳早期新陈代谢和后期的生产性能.妊娠后期母牛遭受热应激同样损害胎儿的发育和生长,抑制犊牛的免疫能力.研究表明,对管理者而言,应采取切实可行的方法消除热应激,以此来提高奶牛生产性能,保障犊牛健康生长.

Heat stress during late gestation has profound effects on cows during the pre- and postpartum periods. In addition to impaired immune function during the transition period, heat stress during the dry period adversely affects mammary gland development before parturition and exerts residual effects on metabolism in early lactation and subsequent lactational performance. Maternal heat stress in late gestation also compromises placental development and fetal growth and negatively affects the immune competence of the offspring. These observations suggest the importance of heat stress abatement as an easily implemented method for managers to improve dry cow performance and calf health and growth.
