测定西北农林科技大学教学试验农场种猪场健康、繁殖正常的147头长白母猪的窝产活仔猪数(X)、初生窝重(y1)、断奶窝重(y2),分别按照窝产活仔猪数分组进行方差分析和性状间的相关回归分析。
5) litter size
窝产仔数
1.
This paper discussed the physiology mechanism of prolificacy and reviewed the reasons and effectiveness of using placental efficiency as a selection tool for litter size and the relationship between placental efficiency and growth traits in pigs.
本文综述了猪高繁殖力的生理机制研究进展 ,对近年来关于猪胎盘效率与产仔数关系以及胎盘效率与生产性状间的关系研究进行了详细描述 ,从胎盘效率这一综合指标探讨猪高繁殖力的生理基础 ,目前的研究结果表明 ,基于胎盘效率的选择是提高猪的窝产仔数行之有效的方
2.

结果表明 :全人工授精、人工授精同自然交配结合等配种方式与自然交配对照组相比 ,分娩率和窝均产仔数差异不显著 ;3至6胎母猪的分娩率高于其它胎次 ,而窝产活仔数 3至 5胎高于其它胎次 ,不同配种方式对各胎次母猪的分娩率和窝均产活仔数无显著影响 ;常温 (17℃ )保存 1d的精液输精后 ,与鲜精相比 ,母猪的分娩率和窝均产活仔数无显著差异 ;人工授精技术的应用使每头母猪每年多提供 3。
补充资料：平产
1.与相比较的产量大体相当。 2.顺产。指胎儿经阴道与母体正常分离。
