摘要
为探求不同季节温度条件下配种对母猪繁殖性能的影响,通过对浙江省某猪场近3年母猪繁殖记录统计,按4个季节配种对母猪繁殖性能的影响进行分析。结果表明:夏季配种母猪受孕分娩率(69.67%)和胎均产活仔数(8.34头)最低,分别比春、秋、冬季节配种降低了5.06%(0.21头),4.04%(0.65头),4.62%(0.82头);冬配春产的仔猪初生重最高,每头平均初生重1.34 kg,分别比春、夏、秋多了0.19,0.12,0.07 kg;冬配春产的仔猪育成率较高(85.31%),仅次于春配夏产的仔猪育成率(88.86%)。由此可见,温度对母猪的繁殖性能有很大影响,采用季节性产仔的配种期最适宜在冬季。
In order to explore the effects of mating in the different seasonal temperature conditions on reproductive performance of sows, we made a statistical analysis of sow reproductive record of a Zhejiang pig farm in recent three years. The results showed that： the parturition rate and the number of live born of sow mating in summer is the lowest （69. 67%, 8. 34）, which reduced by 5.06%, 4. 04%, 4. 62% and 0. 21, 0. 65, 0. 82 compared with that in spring, autumn and winter respectively. The average birth weight of piglet born in spring after sow mating in winter was 1.34 kg, which increased by 0. 19, 0. 12 and 0. 07 kg. The rearing rate of piglet born in spring after sow mating in winter was in a high level （85. 31% ）, next to piglet born in summer after sow mating in spring（88.86% ）. Therefore, the temperature has a great influence on reproductive performance of sows, and the optimal mating season is in winter.
