摘 要:选取40日龄布列塔尼亚兔72只,随机分为3组,对照组饲喂试验兔场原用饲料,试验Ⅰ、Ⅱ组分别饲喂两个按不同配方配制的饲料,测定40-70日龄阶段的平均日增重,分析其经济效益。结果显示:对照组和试验Ⅰ、Ⅱ组兔40-70日龄平均日增重分别为53.69 g、69.44g8、4.39g,试验Ⅰ、Ⅱ组均与对照组差异显著或极显著(P〈0.05或P〈0.01);试验Ⅰ、Ⅱ组料重比分别比对照组下降7.28%、12.43%;Ⅰ、Ⅱ组死亡率较对照组分别降低4.17%,只均获利分别比对照组提高25.12%、66.91%。72 Brittang Rabbits at 40-day old were randomly divided into 3 groups, the control group fed the original rabbit feed, the test group Ⅰ , Ⅱ group were fed by two different formulations of feed preparation. The average daily gain at 40-70 days were measured to analyze its economic benefits. The results showed that the average daily gain in the control group and the test group Ⅰ , Ⅱ at 40 - 70-dayold were 53.69g,69.44g,84.39g respectively. There was significant difference or extremely significant difference between the test group Ⅰ , Ⅱ and the control group ( P 〈 0.05 or P 〈 0.01 ). Compared with the control group, the ratio of feed to body weight in the test group Ⅰ , Ⅱ decreased 7.28%,12.43% respectively, mortality rate decreased 4. 17%,4. 17% respectively, and profit in test group Ⅰ , Ⅱ increased 25. 12%, 66.91% respectively.
