为观察不同铁源对吉富罗非鱼（ Oreochromis niloticus）生长及表观消化率的影响，试验以初重6.79 g左右的吉富罗非鱼为饲养对象，采用酪蛋白、糊精为主要原料制成半精制日粮，分别添加铁含量相等（100 mg/kg饲料）的硫酸亚铁、氯化铁、氯化亚铁、柠檬酸亚铁、卟啉铁，饲喂吉富罗非鱼70 d。结果显示，在铁含量相等（100 mg/kg饲料）的半精制日粮中添加氯化亚铁，吉富罗非鱼的增重率显著（ P＜0.05）高于其它四种铁源。以增重率为指标，吉富罗非鱼日粮中适宜以氯化亚铁作为添加铁源。

In order to study the effects of diets with different iron sources on the growth performance and apparent digesti -bility in Oreochromis niloticus, the O.niloticus with approximate initial weight of 6.79 g were fed with daily diets varied of 5 iron sources for 70 days under water circulating system .The daily diets were mainly formulating by casein and dextrin with the same Fe amount level (100 mg/kg) from different iron sources, ferrisulphas (FeSO4· 7H2O), ferric chloride (FeCl3· 6H2O), ferrous chloride (FeCl2· 4H2O), ferrous citrate(Fe3(C6...
