摘要
选择３３日龄的断奶幼兔３０只，分为３组，按２０％、３０％、４０％的光叶紫花苕草粉的不同比例配入饲粮，除粗纤维外，饲粮其它营养指标基本一致。６０天试验结果表明：２０％草粉组饲喂效果最佳，日增重分别比３０％组和４０％组提高１３．０２％（Ｐ＜０．０５）和２２．１５％（Ｐ＜０．０１）；饲料报酬分别提高１．１％（Ｐ＞０．０５）和９．３％（Ｐ＜０．０５）；幼兔存活率分别提高１２．５０％和１２．５０％，为此建议在断奶幼兔饲粮中配入２０％的优良干草粉，饲粮粗纤维控制在８％～１０％的水平较为理想。
weaning rabbits aged 33 days were divided into 3 groups and fed with the same basic diet supplemented with powder in proportion as 20%.30% and 40% respectively. The nutritional indexes of diet were kept at the same level except crude fibre. The feeding experiment was conducted for 60 days and an excellent result was observed in 20% group. Compared to 30%,40% groups,daily gain in 20% group increased 13.02%(P<0. 05) and 22. 15% (P<0.01) ;feed reward increased 1.1% (P>0. 05) and 9. 3%(P<0.05); survival rates of young rabbits increased 12. 50% and 12. 50% as well. The results indicated that a diet added 20% high quality grass powder and crude fiber ranged from 8% to 10% would promote the growth performance of young rabbits.
