摘　　要：应用红外传感器系统研究了夏季断奶母猪发情行为与配种。结果表明,母猪断奶后第4天发情表现达到最高潮;环境温度对母猪发情及配种影响极显著,断奶母猪正常发情并成功配种的环境温度应不高于23℃。此项研究对准确鉴定母猪的发情、适时配种及环境调控有着重要意义。Oestrus behavior and insemination of weaning sows in summer were studied using infrared sensor system. Results showed that the oestrus behavior reached the highest value on the fourth day after weaning, it is said that the oestrus performance of sows reached its climax. The effects of ambient temperature on oestrus behavior and insemination of weaning sows were highly significant, the ambient temperature for normal oestrus and successful insemination of weaning sows should not be higher than 23℃.
