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.
