摘　　要：试验旨在比较研究不同色型獭兔(海狸色獭兔、培育品种白獭兔、普通白獭兔)生产性能之间的差异。选择健康的体重相近的35日龄断奶海狸色獭兔、培育品种白獭兔及普通白獭兔各60只,饲喂相同的试验饲粮。试验期115 d。结果表明:⑴海狸色獭兔早期(35、60、90日龄)体重最高(P<0.01);120日龄时,海狸色獭兔与培育品种白獭兔体重差异不显著(P>0.05),均高于普通白獭兔;150日龄时培育品种白獭兔体重最高(P<0.05)。⑵不同色型獭兔不同部位被毛密度、长度均以培育品种白獭兔最高,海狸色獭兔最低;臀部皮张厚度培育品种白獭兔与普通白獭兔差异不显著,均极显著高于海狸色獭兔(P<0.01)。⑶培育品种白獭兔与普通白獭兔粗纤维、粗脂肪消化率之间差异不显著(P>0.05),均显著高于海狸色獭兔(P<0.05);海狸色獭兔的中性洗涤纤维消化率显著低于普通白獭兔(P<0.05),与培育品种白獭兔差异不显著(P>0.05);不同色型獭兔其他营养物质消化率差异不显著(P>0.05)。The aim of this study was to compare productive traits in 3 breeds（Beaver Rex rabbit,Raised White rabbit, Common White rabbit）.Selected healthy 35 day weaning Beaver Rex rabbit, Raised White rabbit and Common White rabbit of the same body weight, 60 for each line,and fed the same experimental diet, the experimental period was 115 d.The results shows that：（1） The early period,Beaver Rex rabbit（35,60,90 d） has the highest body weight（P〈0.01）;while at 120 days, the body weight of beaver Rex rabbit and Raised White rabbit has no significant difference（P〉0.05）, both of these lines are higher than Common breeds; at 150 days, Raised White breed have the highest body weight（P〈0.05）.（2）The hair density and hair length in different body part of different colortyped Rex rabbit are highest in Raised White breed, and lowest in Beaver Rex rabbit; the thickness of fur in buttocks have no significant differences between Raised White rabbits and Common White rabbits,all extremely significantly higher than Beaver Rex rabbit（P〈0.01）.（3）The digest rate of crude fiber and crude fat of Raised White rabbit and Common white rabbit are not significant（P〉0.05）, both of the index are significantly higher than Beaver Rex rabbit（P〈0.05）, while the digest rate of NDF in Beaver Rex rabbit is significantly lower Common White rabbit（P〈0.05）, and have no significant difference with Raised White rabbit（P〉0.05）; the digest rate of other nutrients have no significant difference between the three breeds（P〉0.05）.
