| 摘 要： | 采用对比试验,将120只1日龄AA肉鸡分为2组(对照组和试验组),每组3个重复,每个重复20只鸡。对照组不添加褪黑素,试验组添加褪黑素10mg/kg,研究褪黑素对肉鸡生长性能及免疫机能的影响。试验结果表明:试验期间,鸡的平均日增重(ADG)、饲料转化率(FCR)差异显著(P<0.05);平均日采食量(ADFI)差异不显著(P>0.05);胸腺、脾脏、法氏囊指数试验组显著高于对照组(P<0.05)。

| Abstract: | The experiments were conducted to study the efects of melatonin on growth performance and immune functions of broiler.120 1-day-old broilers were randomly allotted into 2 treatments(control group and experimental group) with 3 replicates in each treatment.The control group was fed with diet without supplementation of melatonin and the trial group was fed with the diet supplemented with 10 mg/kg melatonin. The results showed that that adding 10 mg/kg melatonin improved ADG and FCR significantly(P<0.05).But there are not significantly difference(P>0.05) for ADFI.Adding 10 mg/kg melatonin significantly influenced thymus index、bursa of fabricius index and spleen index(P<0.05). |
