摘要
本文对生长肥育猪日粮中添加６０ｍｇ／ｋｇ蛋氨酸铁（蛋氨酸铁组）、６０ｍｇ／ｋｇ硫酸亚铁（硫酸亚铁组）的效果进行了研究．试验结果表明，蛋氨酸铁组肉猪的日增重、饲料效率和经济效益分别比对照组提高６．８５％～９．２５％、７．０４％～９．２３％和３５．８４％～４０．０３％，也相应地比硫酸亚铁组提高９．３０％、３．２１％．和２１．４３％．香氨酸铁是肉猪生产中值得推广的有效铁剂．
The experiments were carried out on the effect of iron-methionine chelated (MFe, 60PPm Fe)and FeSO4(60PPm Fe) on growing-finishing The.results showed that the daily gain, feed efficiency andeconomy of gain inMFe group were 6.85-9.25%, 7.04-9.23% and 35.84-40.03% respectively more thanthose in control group and were 9.30%, 3.21 % and 21.43% respectively more than those in FeSO4 group,too. Therefare, it is iron-methionine chelated that is an effective iron agent in swine production.
