摘要
采用高温增繁饲料添加剂、人工授精和人工辅助自然交配、改善营养水平和环境条件、选留耐高温种用公兔等项综合措施,使毛用家兔在高温季节保持正常繁殖水平。两年试验结果:母兔受胎率为89.3％,母兔产仔率为98.7％,断奶仔兔成活率为84.2％,适繁母兔能在34℃配上种,36℃顺产。
The Angora rabbit could be made to maintain their normal reproductive level by applying integrative measures. The measures included supplementing feed additives to the ration,artificial insemination and manual assistance during natural mating,increased nutritional level and the selection of heat-tolerant bucks. The results of the experiments in two years showed that:the conception rate of the does was 89. 3% ;the survival rate of the weaned young rabbits was 84.2% .Breeding does could be fertilized under conditions of 34℃ ambient temperature and could carry out natural parturition at 36℃ ambient temperature .
