【摘要】 1日龄艾维茵肉鸡健雏420只,随机分为7组,分别喂以对照日粮(Cu11mg/kg)和高铜日粮6周,以放射免疫法研究日粮高铜对雏鸡血清IL-2含量的影响。高铜Ⅰ组雏鸡血清IL-2含量升高,4、6周龄的IL-2含量与对照组比较差异显著(P<0.05);日粮铜含量超过300mg/kg,雏鸡血清IL-2含量程度不同地降低,与日粮含铜量呈负相关。结果表明:日粮含铜100mg/kg对雏鸡血清IL-2合成有明显的促进作用,日粮含铜300mg/kg及其以上对IL-2合成产生程度不同的抑制作用。更多还原

【Abstract】 The experiment was conducted to study the effect of high copper dietary on the serum Interleukin-2(IL-2)contents in the chickens by radioimmunoassay.420 one-day-old Avian chickens were randomly divided into seven groups,and fed on diets as follows:1.controls(Cu 11 mg/kg)and 2.high copper groups for six weeks.The serum IL-2 contents were higher in groupⅠthan in control group when chickens were 4 and 6 weeks old(P<0.05).IL-2 contents in high copper group Ⅳ,groupⅤ and Ⅵ group decreased significantly in comparison with those of control group.The results showed that 100mg copper/kg diet was helpful for the serum IL-2 synthesis in chicken and dietary copper in excess of 300 mg/kg diet reduced the serum IL-2 contents.更多还原
