摘　　要：统计分析了初产母兔、1.5岁以内经产青年母兔、1.5～2.5岁壮年母兔以及2.5岁以上老龄母兔共113只的繁殖成绩,探讨年龄对繁殖性能的影响。结果发现,年龄因素对初生窝重、21日龄窝重、断奶窝重以及断奶仔兔均重的影响极显著(P<0.01),其中经产青年母兔繁殖性能最好,老龄母兔繁殖性能最差。113 reproductive traits of primipara rabbits,multiparity rabbits of 1.5 years old,rabbits of 1.5 to 2.5 years old and rabbits over 2.5 years old were collected and analysised to investigate the influence of them by age.The results showed that the age had a great significant influence on litter weights at birth,at 21 days and at weaning and average weaning weight(P<0.01).It was concluded that multiparity rabbits of 1.5 years old showed the best while the rabbits over 2.5 years old showed the worst reproduction performance.
