中草药添加剂提高家兔生长性能研究

选取断奶家兔32只,随机分成4组,各组饲料分别添加中药0 g/kg(Ⅰ,对照)、6 g/kg(Ⅱ)、9 g/kg(Ⅲ)和12g/kg(Ⅳ)。试验期60 d,测定各组初始体重、期末体重以及饲料消耗量,评价中草药饲料添加剂对家兔增重和料肉比的影响,并对各组经济效益进行比较。结果显示,试验Ⅱ、Ⅲ、Ⅳ组平均日增重分别比对照组提高13.67%、18.28%、20.92%,且差异显著(P<0.05);试验Ⅱ、Ⅲ、Ⅳ组料肉比分别为3.59∶1、3.51∶1和3.46∶1,分别比对照组降低6.02%、8.11%和9.42%,且差异显著(P<0.05);试验组Ⅱ、Ⅲ、Ⅳ经济效益分别比对照组提高19.8%、25.8%和29.1%(P<0.05)。

Effect of Chinese herbal medicine feed additive on the growth performance of rabbits

32 weaned rabbits were devided randomly into 4 groups which were Ⅰ,Ⅱ,Ⅲ and Ⅳ.Then Chinese herbal medicine additive were added to their feed at 0 g/kg(Ⅰ,as control),6 g/kg(Ⅱ),9 g/kg(Ⅲ)and 12g/kg(Ⅳ),respectively.The initial weight,terminal weight,feed consumption and economic benefit of each group was measured to gauge the influence of Chinese herbal medicine feed additive on the growth performance of rabbits.The results showed that compared with Ⅰ,the average daily gains of Ⅱ,Ⅲ and Ⅳ was significantly increased by 13.67%,18.28% and 20.92%(P<0.05),the feed conversion ratios was significantly decreased by 6.02%,8.11% and 9.42%(P<0.05),and the economic benefits was significantly increased by 19.8%,25.8% and 29.1%,respectively.
