摘要/Abstract

摘要： 利用通径分析、决定系数分析及多元逐步回归分析等方法找到了影响杜洛克猪新品系60 d窝重的主要繁殖性状是60 d活仔数、20 d活仔数、60 d个体重及20 d个体重，而初生重、初生窝重和产活仔数影响较小。60 d窝重的最优回归方程为：Y=2.1836X⁴-15.6442X⁵-11.4572X⁶+18.129X⁷+6.9936X⁸-44.6259。

Abstract: The major breeding traits which affected the litter weight of new line Duroc pigs at 60-day-old were found by using path coefficeient,determination coefficient and multi-factor gradual regression analysis.60-day litter size,20-day litter size,60-day weight and 20-day weight had great influence, but the birth weight,liveborn weight and number born alive had little influence .The optimal regression equation which affected the litter weight at 60-day-old was Y=2.1836X⁴-15.6442X⁵-11.4572X⁶+ 18.192X⁷+6.9936X⁸-44.6259.
