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.
