摘 要: 选用21日龄AA肉仔鸡公鸡279只,按体重随机分为3组,分别添加120mg/kg的金霉素、600mg/kg的芦荟粉和300mg/kg的蜂胶进行了饲养试验和代谢试验。试验结果表明,芦荟粉和蜂胶的添加显著(P<0.01)提高肉鸡的日增重;分别比抗生素组提高81.99%和64.62%;料重比各组差异显著(P<0.05);代谢试验结果表明:芦荟组和蜂胶组显著提高了(P<0.01)蛋白质和脂肪的利用率,而其余各养分的代谢率各组间均差异不显著(P>0.05)。 twenty-one days old broiler were randomly assigned to three groups by their weight . Antibiotic,Aloe and Propolis were respectively added to the feeds at the level of 120mg/kg ,600ma/kg and 300mg/kgto form three experiments'diets.The group that diets treated with antibiotic is control group;and two others group are test group.48d of age broiler were killed and test.The result showed that diets treated with Aloe power and Propolis have significantly increase(p<0.01)daily weight gain;have respectively increase 81.099% and 64..62% in two test group broiler.Feed conversion ratio is difference (p<0.05)among the three group.The result of digesting trial showed that diets treated with Aloe power and Propolis have significantly increase(p<0.01)fat digested ratio;have respectively increase 81.099% and 64..62% in two test group,but did not affect (p>0.05) the digested ratio of others nutritional factors .
