母牛产后康复的综合管理策略与实践研究OA

Postpartum recovery of dairy cows is a key link to improve reproductive efficiency,ensure milking performance and extend production life.This article reviewed the physiological changes of dairy cows after calving,and explored the key tech-nologies of postpartum recovery from the dimensions of nutritional regulation,disease prevention and control,reproduction management and optimization based on domestic and foreign research results.It is believed that scientific postpartum care can significantly shorten the time of uterine involution(shortening more than 40 of the control group),reduce the incidence of mas-titis(reducing by 60%-80%),and improve the conception rate of estrus(improving to than 75%).This paper proposes a preci-sion rehabilitation plan based on individualized monitoring,providing theoretical basis and practical guidance for large-scale farms.
