通过川白獭兔母兔主要繁殖性状的测定,分析断奶窝重与其他繁殖性状的相关关系,并进行了通径分析,结果表明,35 日龄断奶只数和21 日龄窝重对 35 日龄断奶窝重直接影响最大,且差异极显著(P<0.01),优化的回归方程为:Y=1.21690X4+503.48538X6-1018.75693;但其决定系数仅为0.5145,说明对影响因素的估计还不完全,影响川白獭兔断奶窝重的因素部分找到,用这些性状组成的回归方程具有部分参考价值,仍有大部分变量对35 日龄断奶窝重产生了较大影响,需要进一步挖掘其他变量.
Correlation analysis between weaning litter weight and other reproductive traits of Chuanbai Rex rabbits
The correlation between weaning litter weight and other reproductive traits was analyzed by measuring the main reproductive traits of female Rex rabbits,and path analysis was conducted.The results showed that the number of weaning piglets at 35 days of age and the litter weight at 21 days of age had the greatest direct influence on the litter weight at 35 days of age,and the difference was extremely significant(P<0.01).The optimized regression equation was as follows:Y=1.21690X4+503.48538X6-1018.75693;However,the coefficient of determination was only 0.5145,indicating that the estimation of the influencing factors was not complete.Some factors affect-ing the weaning litter weight of Sichuan white Rex rabbits were found,and the regression equation composed of these traits had some refer-ence value.Most variables still had a greater impact on the weaning litter weight at 35 days of age,and other variables should be further ex-plored.
