摘　　要：选用60日龄体质量均匀、健康的塞北乌骨鸡120只，随机分为I～V个试验组，每个试验组设4个重复，每个组6只乌骨鸡（雌雄各半），探讨饲粮中添加不同水平能量（10．38，10．94，11．51，12．34，12．96MJ／kg），对塞北乌骨鸡体增质量、血液指标和免疫器官的影响。结果表明。育成期公鸡在12．34MJ／kg时体增质量最高，母鸡在12．96MJ／kg时体增质量最高；80日龄时公鸡调节血糖的能力优于母鸡，对肝脏具有很好的保护力；LDL—C与日粮能量引起体质量的变化具有一定的相关性。总胆固醇的含量在育成期随着日粮中能量水平的增加而逐渐下降。日粮能量水平不同，对内脏器官的影响也不同，都存在不同的显著性差异。One hundred and twenty 60-day-old Saibei silkies were randomly divided into 5 treat- ments,with 4 replicates of 6 broilers each. The based diets were supplemented with 0. 38,10. 94, 11.51,12.34,12.96 MJ/kg metabolic energy（ME）. The results showed that daily weight gain of male was the highest when ME was 12.34 MJ/kg,but female was the highest when ME was 12.96 MJ/kg;the adjustive ability of GLU in male was better than female;both I.DL C and body changes by ME was correlative. TCHO was degressive with increased ME. The result indicated that organs indices were different with the ME of diet.
