摘要
试验研究了日粮中不同赖氨酸添加水平对0～3周龄肉仔公鸡生产性能和胴体品质的影响,各组的基础日粮相同,试验设6个赖氨酸处理水平,分别为0.65%、0.80%、0.95%、1.10%、1.25%和1.40%。将1日龄AA肉仔公鸡450只分成6个处理,每个处理5个重复,每个重复15只。结果表明:赖氨酸水平对0～3周龄肉仔公鸡采食量、平均日增重、饲料转化效率、全净膛率、胸肌率、腹脂率均有显著影响。赖氨酸含量达到1.1%～1.25%才能维持肉仔鸡正常快速生长及较好的胴体品质。
AA broilers were fed to21days old to investigate the effects of dietary lysine levels on growth per-formance and carcass quality of broilers.Dietary lysine levels were0.65%,0.80%,0.95%,1.10%,1.25%and1.40%.Re-sults showed that dietary lysine levels could significantly influence the growth and carcass quality of broilers,and lysine requirement for optimum growth performance and carcass quality was between1.10%and1.25%.
