摘　　要：选择刚离乳的雄性KM小鼠 4 0只 ,随机分为 4组 ,每组 10只 ,饲养 2 8d。在Ⅰ、Ⅱ、Ⅲ、Ⅳ各组小鼠的每千克饲粮中分别添加 0、2、10、5 0mg的吡啶羧酸铬 ,研究铬对小鼠的总蛋白、球蛋白、白蛋白、葡萄糖、总胆固醇、甘油三酯、尿素 7种血液生化指标的影响。试验结果显示 :添加 5 0mg吡啶羧酸铬的第Ⅳ组小鼠血清总蛋白、球蛋白、白蛋白显著低于第Ⅰ、Ⅱ、Ⅲ组 (P <0 0 5 ) ;葡萄糖、甘油三酯显著高于其他三组 (P <0 0 5 ) ;胆固醇、尿素无显著差异。在第Ⅰ、Ⅱ、Ⅲ组中 ,添加 0、2、10mg的吡啶羧酸铬后降低了血清中尿素的含量 (P <0 0 5 ) ,对其他血清生化指标方面无显著影响。weaning male mice were selected and randomly divided into 4 groups, 10 of each group, and raised for 28 days. 0,2,10,50 mg·kg^(-1) chromium piolinate were supplied into the diets of each group, the effects on serum biochemical parameters were investigated. Result showed that 50 mg·kg^(-1) chromium piolinate was negative on the parameters of mice, total protein, globulin, albumin of serum were all significantly lower than that of the former 3 groups (P<0.05); glucose, triglyceride were significantly higher than other group (P<0.05); 2, 10 mg·kg^(-1) chromium piolinate had not apparent influence on the growth index of mice. It can be concluded that 50 mg·kg^(-1) chromium piolinate supplementation decreased the containing of urea and no influence on the other serum biochemical parameters.
