采用综合输精措施提高母猪繁殖性能的试验报告

摘要

The experiment assisted artificial insemination to sow by using comprehensive insem-ination measures based on the national standarel of NY/636-2002. The result showed that the estrus conception rate added up to 85.71% and 86.32%(86.23% on average)for first farrowing sows, 86.67% and 86.96% (86.88% on average)for multiparous sows. There was not significant difference between the different varieties. The litter size of Black pigs was 8.53±1.63(average),York pigs′ was 11.08 ±0.41, there was significant difference between the two different breeds, but first farrowing sows and multiparous sows of York pigs was not significantly different. The result indicated that com-prehensive insemination measures could improve sows′ reproductive performance effectively,especially the estrus conception rate for first farrowing sows.%本试验在国标NY/636-2002母猪输精操作程序的基础上采用综合输精措施来辅助人工授精，结果显示：采用综合输精措施后，初产母猪的情期受胎率可达85.71%和86.32%（综合86.23%），经产母猪可达86.67%和86.96%（综合86.88%），两者间差异不显著，不同品种间的差异也不显著；黑猪产仔数为8.53±1.63，与约克猪产仔数（11.08±0.41）间的差异极显著，但约克猪经产和初产母猪本品种内的差异不显著。本试验说明采用综合输精措施能够有效提高母猪的繁殖性能，尤其是初产母猪的情期受胎率。
