摘要
通过对十个猪场的降温方式及母猪生产性能进行调查,探讨湿帘降温对母猪生产性能的影响。湿帘降温猪舍温度比非湿帘降温猪舍温度低3~9℃,相对湿度高3个百分点;湿帘降温母猪与非湿帘降温母猪相比,平均产活仔数提高3.7头,返情率降低9个百分点,缩短了断乳至发情时间间隔。湿帘降温对母猪生产性能的影响明显。
The wet curtain cooling of piggery compared with the non-wet curtain cooling of piggery,temperature was 3 ~9℃ lower,relative humidity was 3% higher. Wet curtain cooling sows compared with the non-wet curtain cooling sows,a 3.7 increase in the number born alive,return estrus was 9% lower,the time between weaning to re estrus was shortened. Wet curtain cooling had significant effect on the production performance of the sows.
