摘要
利用黄系獭兔杂交改良农户饲养的獭兔,后代的产仔数、出生个体重、初生窝重、断奶窝重、断奶成活率分别提高11.53%、12.52%、9.77%、15.34%、12.76%;5月龄体重、商品獭兔皮合格率分别提高10.95%、38.07%,与本地獭兔生产性能比较差异极显著(P<0.01)。说明黄系獭兔与当地低生产力獭兔杂交,能产生较高的杂交优势。
The number of offspring, the weight of the birth weight, the weaning nest weight, the survival rate of weaning were increased by 11.53%, 12.52%, 9.77%, 15.34% and 12.76% respectively, and the 5 month old weight and the qualified rate of the skin of the Rex rabbit were increased by 10.95% and 38.07% respectively, and the production performance of the local Rex rabbits was poor. The difference was significant（P〈 0.01）. This indicates that crossbreeding between yellow Rex Rabbit and local low productivity Rex rabbit can produce higher heterosis.
