| 摘 要： | 选用360只1日龄体重相近的健康AA肉公雏，随机分成5组，每组6个重复。5个试验日粮可消化苏氨酸水平分别为0．53％、0、60％、0．67％、0．70％和0．73％。结果表明，日粮苏氨酸水平显著影响肉仔鸡日增重和饲料转化率，以生长性能为指标确定的可消化苏氨酸需要量为0．60％，Thr／Lys为60％。日粮中添加苏氨酸显著提高了肉仔鸡细胞免疫和体液免癌功能．

| Abstract: | Three hundred and sixty one-day aged AA broilers were randomly allocated to 5 dietary treatments with 6 replicates of 12 male chicks. Dietary digestive threonine levels were 0.53%,0.60%,0.67%,0.70%,0.73% for 5 trail diets, respectively. The results showedthat dietary threonine levels affected daily gain feed efficiency significantly. Immune function was significantly improved by Thr level. |
