| 摘 要： | 选用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（Cu 11 mg/kg）和高铜日粮（Cu 100mg/kg,高铜Ⅰ组;Cu 200 mg/kg,高铜Ⅱ组;Cu 300 mg/kg,高铜Ⅲ组;Cu 400 mg/kg,高铜Ⅳ组;Cu 500 mg/kg,高铜Ⅴ组;Cu 600 mg/kg,高铜Ⅵ组）6周,观察日粮铜添加水平对雏鸡胸腺、法氏囊的影响.结果表明,与对照组比较,高铜Ⅰ、Ⅱ组雏鸡胸腺、法氏囊的组织学变化不明显,且体积增大,重量增加;高铜Ⅲ、Ⅳ、Ⅴ、Ⅵ组雏鸡胸腺、法氏囊结构中淋巴细胞数量减少明显,且体积减小,重量降低.与对照组比较,日粮铜含量100~200 mg/kg对雏鸡中枢免疫器官发育有促进作用,日粮铜含量300~600 mg/kg不同程度地损伤了雏鸡中枢免疫器官的发育,使免疫功能受损.

| Abstract: | To study the effects of high copper on the thymus and bursa of Fabricius in the chicken,420 one-day-old Avian chickens were randomly divided into seven groups,and fed on diets as follows：1.controls（Cu 11mg/kg） and 2.high copper（Cu 100 mg/kg,high copper group Ⅰ;Cu 200 mg/kg,high copper group Ⅱ;Cu 300 mg/kg,high copper group Ⅲ;Cu 400 mg/kg,high copper group Ⅳ;Cu 500 mg/kg,high copper group Ⅴ;Cu 600 mg/kg,high copper group Ⅵ） for six weeks.The results as follows：In comparison with those of control group,chicken thymus and bursa histology of copper groupⅠ,Ⅱdid not change significantly,and both of the volume and weight increased,high copper Ⅲ,Ⅳ,Ⅴ,Ⅵ group chicken thymus and bursa structure,the number of lymphocytes chicken thymus and bursa histology of copper group Ⅲ,Ⅳ,Ⅴ,Ⅵ reduced significantly,and the volume was reduced,and weight decreased.It was concluded that dietary copper content of 100～200 mg/kg could promote the development of thymus and bursa of chicken,and dietary copper more than 300 mg/kg could inhibit the development of thymus and bursa of the chicken at different levels. |
