摘要
选用齐卡父系兔 (L)、德国巨型白兔 (G)、比利时兔 (B)和哈白兔(H)、齐卡新西兰白兔 (N)等五个品种 (系 )与新品系A兔进行配合力测定 ,提出适合我国肉兔不同生产方式的新品系A兔最佳配套利用模式 (LAN)和简化制种模式 (LA)。结果表明 ,其配套生产的商品兔 ,平均胎产仔数分别为 8 1 7和8 0 9只 ,90日龄均重达 2 5 3和 2 45kg ,饲料 /增重为 3 2 8∶1～ 3 34∶1 (含干草粉 ) ,育肥期成活率达 95 % ,全净膛屠宰率分别为 5 2 1 5 %和 5 1 1 9%。其综合生产成绩显著优于我省目前在生产中广泛推广的二元杂优商品兔。
In this study,5 meat rabbit breeds (strains),including ZIKA male line (L),ZIKA New Zealand White Rabbit(N),German Great White Rabbit(G),Belgian Rabbit(B) and Haerbin White Rabbit(H),were used to estimate the combining ability of the new Line A(A). Two mating modes that were suitable to different producing ways in our country were establised,The best one was LAN and the simple one was LA. The average litter size commercial rabbits amounted to 8 17 and 8 09,respectively, and the body weight at 90 day old,feed/weight gain (including dry grass powder),slaughtering rate(the carcass,liver,lung,heart,kidney were excluded) were 2 53kg,2 45kg,3 28∶1,3 34∶1,52 15% and 51 19%,respectively,and the survival rates amounted to over 95%.The comprehensive performance was significantly better than that of the simple two way crossing commercial rabbits,which were extended widely in meat rabbit production in Sichuan province at present.
