摘　　要：目的：采用翻转肠囊法研究雏鸡离体空肠对硫酸铜、氧化铜和纳米氧化铜的吸收速率。方法：选取50日龄白莱航公雏鸡9只,随机分为3组,扑杀后取空肠制成3段翻转肠囊,翻转肠囊长4~5 cm,进行体外培养。1~3组培养基质中分别以硫酸铜、氧化铜和纳米氧化铜的形式添加铜16 mg/L。结果：在培养时间为0.5、1和1.5 h,空肠对纳米氧化铜的吸收速率显著高于硫酸铜和氧化铜（P〈0.05）,纳米氧化铜组空肠肠壁铜沉积极显著高于硫酸铜和氧化铜组（P〈0.01）。结论：试验表明,雏鸡离体空肠对纳米氧化铜的吸收速率显著高于硫酸铜和氧化铜。Objective：The everted jejunum sac experiment was used to study the absorption rate of CuSO4,CuO and nano-CuO in jejunum of chickens in vitro.Method：Nine fifty-day-old White Leghorn chickens were divided into 3 groups randomly,and separated jejunum to prepare 4～5 cm everted sac to culture in vitro.Each chicken was made 3 segments everted sac.The nutrient solution of groups 1 to 3 were added with Cu 16 mg/L in form of CuSO4,CuO and nano-CuO,respectively.Result：The results showed that： the jejunum absorption rate of nano-CuO was significantly higher（P0.05）than that of CuSO4 and CuO within 0.5 h,1 h and 1.5 h.The copper contents of the nano-CuO jejunum group were extremely significant higher（P0.01） than that of CuSO4 and CuO groups.Conclusion：The experiment indicates that the jejunum absorption rate of nano-CuO was higher than that of CuSO4 and CuO.
