摘要
１日龄艾维茵肉仔鸡１００只，随机分为２组，每组设有重复，自由采食以玉米、淀粉、葡萄糖和大豆分离蛋白为主日粮，日粮中分别添加０（铁缺乏组）和１１０ｍｇ／ｋｇ铁（对照组），饮用去离子水，分别于１和１４日龄皮下接种ＨＶＴ冻干苗、７和１４日龄滴鼻接种Ｌａｓｏｔａ系冻干苗。试验结果表明，肉仔鸡疫苗接种及饲养管理同前。铁缺乏组与对照组相比：４２日龄肝脏、胸腺、脾脏和法氏囊中过氧化氢酶（ＣＡＴ）活性显著降低（Ｐ＜０．０５）、肝脏、胸腺和脾脏中谷胱甘肽过氯化物酶（ＧＳＨ－Ｐｘ）活性显著降低（Ｐ＜０．０５）；４２日龄肝脏、胸腺、脾脏和法氏囊中脂质过氧化物（ＬＰＯ）含量显著升高（Ｐ＜０．０５）。铁营养状况与机体抗氧化功能密切相关，日粮铁缺乏机体抗氧化功能降低。
The experiment with Fe added at O(Iron deficiency) or 110 mg/kg (Control) was conducted using 100 Avian chicks at 1 days old ,divided into two groups with repeats per group.Deionized water was supplied.All chicks were inoculated by the subcutaneous route with Mareks disease virus(MDV) freeze-dried vaccine at the first(primary) and fourteenth(secondary) day-old,also by the intranasal-intraocular routes with Newcastle disease virus(NDV) freeze-dried vaccine at the seventh(primary)and fourteenth(secondary)day-old.In comparison with basal plus 110 mg Fe/kg diet(Control),basal plus 0 mg Fe/kg (Iron deficiency)diet:the activity of CAT in liver,thymus,spleen and bursa F.was significantly decreased(P<0.05) at 42 d resp.;the activity of GSHPX in liver,thymus,and spleen was significantly declined (p<0.05) at 42 d resp,LPO content in liver,thmus,spleen and bursa F.was Significaltly enhanced(P<0.05)at 42 d respectively.The results indicated that the diet with adding different amount of iron affected Anti-oxida
