摘　　要：以50只60日龄已经开产的朝鲜鹌鹑为研究对象,在饲料中添加不同水平的FeSO4(添加量为4.978、3.485、1.991、0.498、0 g/kg),经过15 d的试验期后,采集鹌鹑心脏、肝脏、小肠、腺胃、肌胃、胸肌和腿肌组织,用原子吸收分光光度法测定其中铁的含量;同时收集试验期第5、10、15天的鹌鹑蛋,用原子吸收分光光度法分别测定蛋清和蛋黄中的铁含量。结果表明,随着饲料中FeSO4添加量的增加,各种组织和鹌鹑蛋中铁含量也逐渐增加,铁在不同组织中的含量差异较大,含量最高的组织是腺胃和肌胃,其次是肝脏,含量最低的是肌肉组织;鹌鹑蛋黄中的铁含量显著高于蛋清中的铁含量。因此,在饲料中添加FeSO4可以明显提高鹌鹑各组织和鹌鹑蛋中的铁含量。A total of fifty 60-day-age quails were selected to feed with different levels of FeSO4（4.978,3.485,1.991,0.498,0g/kg） addition for 14 days.After the raising,all the quails were butchered and samples of heart,liver,small intestine,glandular stomach,muscular stomach,chest muscle and leg muscle were collected and the levels of iron were analyzed by atomic absorption spectrophotometry.The quail eggs were collected at 5th,10th,and 15th day after the beginning of study and the levels of iron in albumen and yolk were analyzed by same methods.The results showed that the deposition of iron in all the tissues and eggs raised with the addition of FeSO4.The glandular stomach and muscular stomach had the highest level of iron,liver had middle level of iron and muscle had lowest level of iron.The level of iron in yolk was significant higher than that in albumen.This indicates that level of FeSO4 in quail feed significantly affects the level of iron in tissues,organs and egg.
