摘　　要：奶牛围产期一般是指产前3周至产后3周这一时期,此时奶牛生理、代谢和免疫功能发生显著变化,会出现不同程度的免疫抑制现象。由于免疫功能下降,此时也是传染病的高发期,严重影响奶牛健康,进而导致产后牛奶品质下降。因此,如何缓解围产期奶牛免疫抑制状态,降低产后的发病率,已成为目前研究的一个热点。本文综述了围产期奶牛发生免疫抑制的原因及用于缓解的营养对策。Periparturient period, defined as 3 weeks before and after parturition, represents a period of signifi-cant changes in physiology, metabolism and immune function of dairy cows. Therefore, the dairy cows suffer from immunosuppression in varying degrees during the periparturient period. Due to decreased immunity, most infectious diseases occur during this period, which impact the health of the cows and then result in decreasing milk quality. Consequently, many investigators have focused on how to attenuate the immunosuppression status and reduce the incidence of postpartum diseases. This article reviewed the occurrence reasons of immunosup-pression in dairy cows during the periparturient period and the nutritional countermeasures.
