卡巴多(Carbadox)对肉用幼兔生长发育的影响

Effectof Carbadox on the Growth Traits of Rabbits

选用 50日龄新西兰白兔 68只 ,随机分为 4组 ,其中 1个为对照组 ,3个为试验组 ,试验组中分别添加 0 .0 1‰、0 .0 2‰和 0 .0 3‰的卡巴多 ,研究其对幼兔生长发育和饲料转化率的影响。结果表明 :试 组、试 组、试 组的全期日增重为 2 7.48g、2 6.38g和 2 8.0 6g,比对照组 2 5.50 g分别提高 7.76%、3.45%和 1 0 .0 4 % ,差异显著 (P<0 .0 5) ,各试验组间差异不显著 (P>0 .0 5) ;3个试验组的料重比分别比对照组低 1 4.36%、1 1 .92 %和 1 5.99% ;以添加 0 .0 3‰卡巴多的经济效益最好。

New Zealand White rabbits,50 days old,affected by dietary Carbadox supplementation (0 .0 1‰ ,0 .0 2‰ and 0 .0 3‰ ) ,were used to study growth traits and feed efficiency.The average daily gains of the three trails were2 7.48g,2 6.37g and2 8.0 6g respectively,7.76% ,3.45% and1 0 .0 4 % (P<0 .0 5) higher than the control's2 5.50 g.The feed efficiencies of the three trails were1 4.36% ,1 1 .92 % and 1 5.99% lower than the control's.The results show thatthe diet with0 .0 3‰ Carbadox may add the profit of the rabbit production.
