【摘要】 在日粮中分别添加0.75,1.50,2.25,3.00mg/kg的烟酸铬来饲养奥尼罗非鱼, 试验结果表明各试验组均能提高鱼增重、降低血糖浓度,其中添加1.5mg/kg烟酸铬组的效果较好,铬主要在肾脏积累,肌肉、肝脏积累较少,添加烟酸铬对鱼的胰岛组织细胞没有影响。
【Abstract】 The diets added with chromium-nicotinate at different levels of 0.75,1.50,2.25 and 3.0mg/kg were used to rear T.anrea×T.nirotica.Experiment results showed that chrominum-nicoti-nate,especially 1.5mg/kg chromium,could improve the weight gain,and reduce glucose concentration in plasma.Chromium was mainly accumulated in kidney, and less in muscle and liver.No effect of chromium-nicotinate on Pancreatic islet was observed.
