| 摘 要： | 用日本大耳白母兔与加利福尼亚公獭兔杂交,其杂种一代母兔再与加利福尼亚公獭兔回交,共繁殖回交一代71只,其中绒毛型兔占42.25％,粗毛型兔占57.75％。将粗毛型兔淘汰,自绒毛型兔中选出理想型公母兔作为基础繁殖群进行横交固定,形成新的獭兔品系VC-I系。VC-I系獭兔(基础群)生长速度及繁殖性能均较纯种獭兔有所提高,毛品质亦保持了纯种獭兔水平。

| Abstract: | The female Japanese White rabbit was crossbred with male Californian rex rabbit. The first fillial(F1) generation was backcrossed with Californian rex rabbit sire of the progeny, the percentage of fur type from such backcross was 42.25%. The ideal fuzz rabbits were selected as a foundation stock for intersect-breeding, and finally a new rex rabbit strain-Veterinary College-I (VC-I) was bred. The VC-I rex rabbit is better than purebred in growth rate and reproductivity. There is no significant difference of fur quality between the two kinds of rex-rabbits. |
