摘　　要：皖Ⅲ系长毛兔是在皖系粗毛兔的基础上，又经过五个世代的系统选育而成的。本研究对其１～５世代选育群的繁殖和生长发育性能进行了系统的测定。结果表明，该品系兔繁殖性能适中，生长发育良好，其头胎产仔７．０６只，产活行６．６３只；初生、２１日龄及４２日龄窝重分别为３４９．０５ｇ，２１６８．１９ｇ和４９０１．１２ｇ，断奶成活率９０％左右。１１月龄体重、体长及胸围分别为４１１７．４１ｇ、５０．７７ｃｍｎ和３２．９９ｃｍ。Based on Wan strain coarse wool Angora Rabbit,Wan Ⅲ Angora Rabbit was bred through systematic selection and breeding for 5 generations. The characters of reproduction and growth were observed. The results showed that the characters of reproduction and growth were moderate,and better than Wan strain coarse wool Angora Rabbit. The average number of the litter was 7. 06,the live litter size was 6. 63,litter weights at birth,the zost day and weaning were 349. 05g, 2168.19g and 4901. 12g respectivehy,and survival rate at weaning was about 90%. Body weight,body length and chest measurment were 4117. 419, 50. 77cm and 32. 99cm respectively.
