摘要
采用通径分析的方法,对塞北兔主要繁殖性状进行了分析。结果表明:塞北兔35日龄断奶窝重与产活仔数、初生窝重、泌乳力之间的相关系数分别为0.646、0.507、0.823,直接效应影响为0.636、-0.407、0.669。通过对决定系数的计算,初步认为影响塞北兔35日龄断奶窝重的早期因素是泌乳力和产活仔数。
Reproductive traits of Saibei rabbit were analysized by the method of path analysis, the results showed as follows： The correlation coefficient between 35 days weaning weight of litter and number of alive birth rabbits, birth weight of litter, milkability were 0.646,0.507and 0.823. Direct contributions among them were 0.636, -0.407 and 0.669. By calculating the determination coefficient, it＇s considered that early factors influencing 35-day weaning weight of litter were milkability and birth numberalive.
