【摘要】 本试验将肉鸡分为4组,每组50只。药物混饲添加,分别为高剂量组(4 ml/kg饲料)、中剂量组(2 ml/kg饲料)、低剂量组(1 ml/kg饲料)、空白对照组不用药。本品连续试验47天,试验过程中第18、30、43天称重,并计算平均值。结果表明,试验药物高、中剂量组肉鸡平均增重与其它试验组差异显著(t>1.96,P<0.05);低剂量组与对照组差异不显著(t<1.96,P>0.05),表明在同样情况下高、中剂量组试验效果较好。更多还原

【Abstract】 The healthy broilers were divided into 4 groups with 50 broilers per group.The compound amino acids and vitamins emulsion was mixed with feeds,and the high dose,the medium dose and the low dose were 4,2 and 1 ml respectively per kilogram feed while the control had no medicine.During 47-day continuous addition,the broilers were weighed on the 18th,30ty and 43rd day respectively.The results showed that the broiler body weight of the high-dose group and the medium-dose group increased significantly compared with the other groups,and the low-dose group had no difference with the control(P>0.05).So the high-dose and medium-dose groups were better under the same conditions.更多还原
