川白獭兔生长发育性能选育研究

Study on the Breeding Growth Performance of Chuanbai Rex Rabbit

通过对川白獭兔连续五个世代的生长发育性能选育,得出其生长性能结果:5周龄断奶体重736.49g,13周龄体重2 309.56 g,23周龄体重3 582.22 g,23周龄体长47.79 cm,断奶至23周龄成活率90.03%,10月龄公、母兔体重分别为3986.77 g、4 080.89 g;除5周龄、8周龄体重与0世代无显著差异外,13周龄、23周龄、6月龄、7月龄、10月龄母兔体重分别较0世代提高91.41 g、323.57 g、257.63 g、207.83 g、210.19 g,极显著高于0世代(P<0.01),生长性能选育进展显著。

The growth performance of the Chuanbai rex rabbit was improved obviously by continuous 5 generation bred. The 5-weeks-old weaning weight, 13-weeks-old weight, 23-weeks-old weight, 23-weeks- old body length, the survival rate from weaning to 23 weeks, and 10-months-old weight of male and female of Chuanbai rex rabbit breeding core group had grown to 736.49 g, 2 309.56 g, 3 582.22 g, 47.79 cm, 90.03%, 3 986.77 g and 4080.89g respectively. The 13-weeks-old weight, 23-weeks-old weight, 6-months-old weight, 7-months-old weight and 10-months-old female weight were 91.41 g, 323.57g, 257.63g, 207.83g and 210.19g obviously higher （P〈0.01） than those of 0 generation. This result indicated that the growth performance of Chuanbai rex rabbit was greatly improved after being bred.
