奶牛交巢穴不同埋线时间对子宫复旧的影响

摘要

In order to explore the correlation between different catgut embedding time in jiaochaoxue and postpartum uterine involution of dairy cows, 20 Holstein cows were chosen. 5 Holstein cows were for control group and the remaining dairy cows were embedded catgut in different time after cow giving birth. Then the detailed lochia eduction and uterine involution of every cow were recorded. As a result, the proper catgut embedding time was in postpartum 1~6 hours, while in the period before or after the above time, the effect is worse, but there was no significant difference between them.%为摸索母牛产后交巢穴不同埋线时间与子宫复旧的相关性，选择20头黑白花奶牛作为研究对象，5头为空白对照组，15头在其产后不同时间进行交巢穴埋线，按照判定标准详细记录每头奶牛的恶露排出及子宫复旧情况。结果显示，产后1～6h埋线效果最好，而1h以内和6h之后埋线效果差异不显著，但均比1～6h之间埋线的效果差。
