| 摘 要： | 为探讨分娩季节对母兔产仔性能的影响,利用2010-2013年度665只齐卡新西兰母兔共计1 649窝次的产仔性能记录,按不同分娩季节进行了比较分析.结果表明：分娩季节极显著影响齐卡新西兰母兔的产仔性状（P＜0.01）,其中春季产仔数、产活仔数、初生窝重以及初生个体重均为最高,秋季产仔数和产活仔数较低,夏季初生窝重和初生个体重最小.由于产仔数是繁殖性能最重要的衡量指标,研究表明,齐卡新西兰母兔繁殖的最佳季节为春季.

| Abstract: | 1 649 litters from 665 ZIKA New Zealand White Rabbits from 2010 to 2013 were choosed to study the influence of delivery season on does littering traits.The results showed that delivery season significantly affected calving traits of females （P＜0.01）.The litter size（LZ）,number of born alive（NBA）,litter weight at birth（LWB） and individual litter weight at birth（IL-WB） in spring were the highest and the LZ and NBA in autumn were in middle,while LWB and ILWB were the smallest in summer.Since the litter size was the most important indicator of reproductive performance,it was suggested that spring was the best breeding season. |
