摘　　要：选用70 d健康黄羽鹌鹑480只,随机分为4个处理,每个处理4个重复,每个重复30只。对照组饲喂基础日粮,试验Ⅰ组、试验Ⅱ组和试验Ⅲ组在基础日粮的基础上分别添加50 mg/kg、100 mg/kg和200 mg/kg的抗菌肽,饲养期35 d。研究结果表明:与对照组相比,日粮中添加50 mg/kg、100 mg/kg和200 mg/kg的抗菌肽对鹌鹑的采食量、料蛋比没有产生显著地影响(P>0.05);有提高产蛋率的趋势,提高幅度分别为0.93%、1.84%和0.85%,但没有达到显著差异水平(P>0.05);显著地提高了蛋壳厚度,提高幅度分别为3.37%、4.86%和5.46%(P<0.05);改善了蛋黄颜色,改善幅度分别为2.31%、12.74%和12.27%(P<0.05)。综合成本与效益,建议在蛋用鹌鹑日粮中添加50~100 mg/kg的抗菌肽。The total of 480 healthy yellow feather quails aged 70 days were selected and randomly divided into 4 groups.The control group was fed a basal diet,Exp.Ⅰ,Exp.Ⅱand Exp.Ⅲgroup were added 50 mg/kg,100 mg/kg,and 200 mg/kg antibacterial peptides on the basis of basic diet,respectively.The feeding period was 35 days.The results showed that compared with the control group,50 mg/kg,100 mg/kg and 200 mg/kg antimicrobial peptides added into the diet had no significant effect on the average feed intake,Feed/egg ratio of quails(P>0.05).There was a tendency to increase the egg yield,with the increases of 0.93%,1.84%and 0.85%,respectively,but there was no significant difference(P>0.05).The thickness of eggshell was significantly increased by 3.37%,4.86%and 5.46%(P<0.05),and the improvement of yolk color was 2.31%,12.74%and 12.27%,respectively(P<0.05).Combined with cost and benefit,it was recommended to add 50-100 mg/kg antimicrobial peptides to quail diet.
