摘要
试验选用19～20日龄昆明普通级小鼠108只,低铜饲养20d后,随机分成3组,每组设3个重复,每重复4只。1组饲喂以大豆分离蛋白-玉米淀粉为主的基础饲粮作为对照;2、3组饲粮中分别加入4.5mg/kg和45mg/kg的硫酸铜以铜计,测定小鼠组织器官中铜浓度及部分免疫学指标,以研究不同水平铜对小鼠营养和免疫功能的影响。
KM mice were allocated randomly into 3 groups with 3 replicates after the base feeding of copper exhaustion for 20 days, 4 mice in each replicate. Mice of group 1 were fed with isolated soya-bean protein-corn starch, and group 2,3 were supplemented with copper 4.5mg/kg? 45mg/kg, in order to investigate the effect of different supplemental level of copper on nutrition and immunity of mice by testing copper concentration in tissue and organ, and some immune index.
