粗纤维及纤维素酶对1～2月龄肉兔能量消化率和生长性能的影响

摘要

According to the meat rabbit fed with six groups of cross-tested dietary combined of different levels of crude fiber (10.0%, 12.0%, 14.0%) and cellulase(0,0. 01%), the effect of that on energy utilization efficiency and growth performance was studied. The results showed that: (l)meat rabbit's growth performance of different crude fiber levels and the presence of cellulase group was no significant difference(PX). 05) ; (2) digestibility of crude fiber and energy of 12. 0% crude fiber level group were significantly higher than other groups(P0. 05).%肉兔对应饲以含不同粗纤维水平(10.0％、12.0％、14.0％)和纤维素酶水平(0、0.01％)交叉组合形成的6组日粮进行试验研究,探讨对能量利用效率和生长性能的影响.结果表明:(1)不同粗纤维水平及有无纤维素酶组的肉兔的生长性能差异均不显著(P＞0.05).(2)12.0％粗纤维水平组粗纤维和能量的消化率显著高于其他组(P＜0.05)；而纤维素酶对养分的利用率并没有明显的提高(P＞0.05).
