奶牛在分娩过程中可能出现难产、产道损伤及胎衣不下等问题,继而容易发生产后子宫炎及子宫内膜炎,影响子宫复旧和后续的繁殖表现。本文将奶牛子宫健康管理作为一个整体,从围产期激素变化、产程划分及管理、难产助产、胎衣不下、产后子宫感染的界定和分类防治等方面,阐述子宫复旧生理和健康管理要点,为奶牛围产期疾病防控及繁殖健康提供依据。
In the process of delivery,cows may have dystocia,birth canal injury and retained placenta,then prone to acute puerperal metritis and endometritis,affecting the uterine involution and subsequent reproductive performance. This trial analyzes the aspects of perinatal hormone changes,division and management of labor process,dystocia and midwifery,retained placenta, definition and classified prevention of postpartum uterine infection in transition period, and expounds the key points of physiological and health management of uterine involution in holstein cows,so as to provide basis for perinatal disease prevention and reproductive health in dairy cattle.
