生长獭兔饲料配方的筛选研究

The Study of Selecting the Feed Formulation of Growing Rex Rabbits

以48只体重相近(2.22±0.07kg)3月龄的獭兔为研究对象,随机分为4组,分别饲喂青干草、青干草+苜蓿、青干草+花生秧、青干草+苜蓿+花生秧四种粗饲料组合的日粮,即分别为试验Ⅰ组、Ⅱ组、Ⅲ组和Ⅳ组,研究其对獭兔生长性能的影响。试验期为67d。结果表明:各试验组之间的结束体重和日采食量差异不显著(P>0.05)。试验Ⅱ组的0-60d日增重显著的高于其它三个组(P<0.05),而其它三个组彼此之间的差异不大(P>0.05)。试验Ⅱ组的饲料转化效率显著地高于试验Ⅰ组和Ⅲ组(P<0.05),与试验Ⅳ组差异不显著(P>0.05),试验Ⅱ组、Ⅲ组、Ⅳ组彼此之间的结果差异不显著(P>0.05)。从经济效益和饲料来源来考虑,粗饲料组合为青干草+花生秧的饲料配方较适合。

Forty-eighty Rex Rabbits of three months were selected and randomly divided into 4 groups.Different group fed hay,hay ＋ alfalfa,hay ＋ peanut vine,hay ＋ peanut vine ＋ alfalfa.This research was to study the effect on the growth performance of Rex Rabbits.The trial period lasted 67d.The results showed that： there is no difference between the groups on final weight and daily intake.The 0-60d daily gain of Rex Rabbits fed hay ＋ alfalfa significantly was higher than the other three groups（P 0.05）,with no significant difference between other three groups（P0.05）.In addition,the feed conversion efficiency of group Ⅱ was noticeably higher than groupⅠand Ⅲ（P 0.05）,but the difference was not significant with group Ⅳ（P0.05）.The difference of the feed conversion efficiency between the group Ⅰ、 Ⅲ and Ⅳ was not significant（P 0.05）.From the economic and food sources,the feed formulation including hay and peanut vine is better.
