摘要
通过对湘潭种猪场１１２６窝母猪繁殖性能的测定及其与主要气候生态因子的相关分析，从而阐述气候因子对母猪繁殖力的影响。研究结果表明，气温过高或过低均对猪繁殖力不利，高温高湿对母猪繁殖力影响最大。
Reproductive performance of 1126 sows were measured in Xiangtan Swine Breeding Farm. The relationship between climatic factors and sow′s reproductive traits were done to investigate the influences of climatic factors on sow′s reproductivity. The results showed that too high or too low temperature has negtive effects on sow′s reproductivity. High temperature with high humidity is the worst to sow′s reproductivity, especially.
