日粮中加入EM发酵菜籽饼对生长育肥兔的增重效果

Effection on the Fatted Rabbits by Adding the EM Fermentation Rapeseed Cake to the Ration

选用3个品种(齐卡兔、豫丰黄兔、虎皮黄兔)35日龄体重(0.625±0.05)kg的生长育肥兔120只,进行日粮中加入EM发酵菜籽饼的饲养试验,试验期49d,试验组日粮中分别加入EM发酵菜籽饼11%、14%、17%和20%。结果表明,日粮中EM发酵菜籽饼加入量在17%时,增重效果最好,与对照组相比,可提高日增重16.7%(P<0.05)、降低料重比14.4%(P<0.05),而采食量却没有显著性差异(P>0.05)。

120 fatted rabbits , aged in 35 - day, average weight of 0.625±0.05kg from 3 breeds （ZIKA, Henan Yufenghuang, Hupihuang） were selected to feed EM fermentation rapeseed cake. The weight of the EM fermentation rapeseed cake in the treatment groups were respectively at 11%, 14%, 17%, 20% of the daily grain, comparing to the control group in the 49 days contrast experiment. The results showed that the weight effeetion was the significant when the EM fermentation rape cake to feed fatted rabbits was in the ratio of 17%. It can enhance daily gain in the ratio of 16. 7% （P〈0. 05） and reduces the ratio of meat production to feed at 14.4% （P〈0. 05）, as compared with the control group, But the intake didn＇ t have the significant difference actually.
