摘　　要：通过在饲料中添加不同梯度的葎草醇提物来研究其对AA肉鸡生长性能和血清生化指标的影响,并确定最适添加量.选用240只1日龄的AA肉鸡,随机分成4个处理组:基础日粮组、试验组Ⅰ、试验组Ⅱ和试验组Ⅲ,葎草醇提物添加量分别为:0、5、10、15 mL/kg.每个处理组6个重复,每个重复10只鸡,试验期为42 d.结果表明:与基础日粮组相比,试验组Ⅱ和试验组Ⅲ能够显著(P<0.05)降低料重比.试验组与基础日粮组相比,能够显著(P<0.05)提高AA肉鸡血清碱性磷酸酶活性、血清总蛋白、球蛋白和磷,能显著(P<0.05)降低血清总胆固醇和甘油三酯,对谷丙转氨酶、谷草转氨酶、白蛋白和肌酸激酶的影响不显著(P>0.05).结果表明,葎草醇提物有改善AA肉鸡生长性能,提高钙、磷、蛋白代谢和增强免疫的作用,其最适添加量为10 mL/kg.We studied the effects of ethanol extracts from Humulus Scandens on the growth performance and serum biochemical parameters of AA broiler chickens by adding different gradients of ethanol extracts in the feedstuff so as to determine the optimal addition amount.We selected 240 1-day-old chickens and randomly divided the chickens into four groups,i.e.the blank group,the first test group,the second test group and the third test group,wherein each group had 6 replicates,and each replicate had 10 chickens;the ethanol extract was respectively added into the feedstuff for four groups by the amount of 0,5,10 and 15 mL/kg;and the chickens are fed for 42 days.The results showed that the second test group and the third test group had remarkably lowered feed-weight ratio in comparison with the blank group;the test groups were significant superior in the serum alkaline phosphatase activity,the total serum protein,serum globulin and serum phosphorus,but had remarkably lower serum total cholesterol and triglyceride in comparison with the blank group;and the ethanol extracts from Humulus Scandens had no remarkable effect（P〉0.05） on the GPT（serum glutamic-pyruvic transaminase）,GOT（serum glutamic-oxaloacetic transaminase）,serum albumin and CPK（serum creatinine phos-phkinaes）.The results showed that the ethanol extract from Humulus Scandens had the effects in improving the growth performance,promoting the metabolism of calcium,phosphorus and protein,and enhancing immunity,and the optimal addition amount was 10 mL/kg.
