| 摘 要： | 通过对银狐主要繁殖性状重复力的估计和分析,为选育和改良银狐提供理论基础。利用具有2次或2次以上产仔记录的248只母银狐627个繁殖成绩和51只公狐211个繁殖成绩记录,估计了银狐主要繁殖性状的重复力。产仔母狐胎平均产仔数、胎平均断奶活仔数、母狐配种日期、母狐妊娠期的重复力分别为0.114、0.007、0.270和0.206,公狐与配母狐平均产仔数、与配母狐平均断奶活仔数、与配母狐受胎率的重复力分别为0.108、0.303和0.206。母银狐繁殖能力和公狐与配母狐的平均产仔数、受胎率等性状主要受非遗传因素所控制。 |

| Abstract: | The repeatability of several major reproductive traits in silver foxes was investigated so as to provide practical guidance for genetic selection and improvement.The repeatability was calculated from 627 records of 248 female and 211 records of 51 male silver foxes.The repeatability of litter size at birth or weaning,mating date,and pregnancy duration in female silver fox was 0.114,0.007,0.270 and 0.206,respectively.The litter size at birth or weaning and conception rate in the mating female foxes were 0.10... |
