摘　　要：选用健康的1日龄艾维茵肉仔鸡144只,随机分成6个处理组,每个处理组3个重复,每个重复8只鸡,饲养6周。分别在基础日粮中添加不同水平的锰,研究其对肉仔鸡血清MnSOD活性及其生长性能的影响,结果表明血清中MnSOD活性可以作为判定锰不足或过量的特异性敏感指标。锰缺乏或过量对肉仔鸡的生长均有不良影响。在本试验条件下玉米-豆粕型肉仔鸡饲粮中锰的最适添加量为80mg·kg-1。One hondred and forty-four Avin birds were randomly divided into six groups with one way random design,each group being 3 replicates (8 birds per replicate). This experiment was conducted to investigate the effects of dietary Manganese on MnSOD activity in serum and broilers′ growth. The results showed that the MnSOD activity in serum could become a sensitive index for dietary Mn levels. Absence or excess of Mn in the dietary either could have a negtive effect on the growth of the broilers. The most suitable Mn supplement in the broiler diets is 80mg·kg-1.
