Abstract
An automated heatmount detection system was employed to detect estrus for artificial insemination in 57 beef cows. First service conception rate was 84.2% and the pregnancy rate was 89.5% for a 42-day breeding season. Duration of estrus was 9.6 h, sx = 0.5 h and mounting activity was lowest during the dark part of the day.
摘要
采用自动热感检测系统对57头肉用母牛进行发情检测，以便进行人工授精。在为期42天的繁殖季节中，首次输精受胎率为84.2%，妊娠率为89.5%。发情持续时间为9.6小时，标准误为0.5小时，爬跨活动在一天中的黑暗时段最低。
