The periparturient period of dairy cows refers to the period from 3 weeks before calving to 3 weeks after calving. During this time, due to significant changes in physiology and metabolism,dairy cows are in a state of immunosuppression, and the incidence and severity of many diseases increase significantly, resulting in higher culling rates and lower production performance, which affects the development of dairy farming. A large number of studies have been conducted to address the characteristics and causes of immunosuppression in periparturient dairy cows. This paper reviewed the mechanisms of immunosuppression in periparturient dairy cows, and it introduced the application of nutritional modulation in improving the immune situation of periparturient dairy cows, aiming to provide a scientific basis and practical guidance for health management of dairy cows in periparturient period.
Key words: dairy cows; periparturient period; immunosuppression
