旨在探究奶牛发情期活动量变化规律,及其受胎次、季节和发情处理方式3个因素的影响,提高计步器发情检测方法检出率。随机选择某奶牛场150头产后健康泌乳牛和7头青年牛,使用计步器自动检测牛发情前后活动量数据,并采用直肠检查进行发情牛确认。结果表明,奶牛发情开始后活动量(>1 500)显著高于间情期(

In order to improve the detection rate of estrus determination via pedometer,the activity alteration of dairy cows affected by parities,seasons and types of estrus treatment was compared before and after estrus.157 randomly selected dairy cows（150 postpartum healthy lactating dairy cows and 7 primiparous ones）in a dairy farm were analyzed in this study.The activity of the experimental cows before and after estrus were measured by pedometer,and the estrus status were confirmed by rectal examination.The detection of pedometer showed that the ac...
