摘　　要：选择同期断奶的生长獭兔180只,随机分成3组,日粮分别按NRC饲养标准(Ⅰ组)、克里莫饲养标准(Ⅱ组)、一料到底饲养标准(Ⅲ组)3个饲喂模式的营养水平配制,观察其对仔兔生长发育、营养物质消化率、被毛品质的影响。结果表明:仔兔90日龄的末重和平均日增重Ⅰ组显著高于Ⅱ组6.41%(P<0.05);平均日耗料量Ⅰ组、Ⅲ组分别比Ⅱ组高10.85%、10.31%,差异均极显著(P<0.01);耗料增重比Ⅲ组比Ⅰ组、Ⅱ组分别高4.58%、4.89%,差异均极显著(P<0.01);营养物质的消化率,Ⅲ组显著低于Ⅰ组、Ⅱ组(P<0.05);被毛品质中,被毛密度Ⅲ组极显著高于Ⅱ组14.99%(P<0.01),被毛长度各组差异不显著(P>0.05)。Total one hundred and eighty about 30 days,healthy growing Rex Rabbits,were divided into three groups randomly.They were fed with different nutritional level ration respectively,according to the NRC feeding standard(Ⅰ),the Kelimo feeding standard(Ⅱ) and the bottom feeding standard(Ⅲ).The growth development,nutrition digestibility,pelt quality were calculated.The experiment results showed that: Body Weight and Average daily gain of 90-day Young rabbits of group Ⅰ were higher than group Ⅱ about 6.41%(P<0.05);Average daily feed intake of groupⅠand Ⅲ were higher than group Ⅱ about 10.85% and 10.31% respectively(P<0.01);Feed/Gain of group Ⅲ was significantly higher than group Ⅰ and Ⅱ about 4.58% and 4.89% respectively,(P<0.01).The nutrient digestibility of group Ⅲ was significantly lower than group Ⅰ and Ⅱ(P <0.05);hair density of Ⅲ group was higher than group Ⅱ about 14.99%,(P<0.01);there is no significant difference of hair length among the three groups(P>0.05).
