在仔猪饲料中添加甘氨酸亚铁能提高仔猪的平均日增重，降低料肉比。氨基酸螯合铁可明显提高生长育肥猪的日增重和饲料利用率。氨基酸螯合铁能够改善育肥猪的肤色以及毛况。与喂给硫酸亚铁的母猪相比，从妊娠期的第一天开始到仔猪断奶阶段喂给同水平氨基酸铁的母猪断奶至发情的间隔缩短0.4 d，且其哺育的断奶仔猪体重明显改善。饲料中添加氨基酸铁有助于促进仔猪的生长。在饲料中添加蛋氨酸铁能够显著提高肉鸡的生长速度，提高它们的日增重。在肉仔鸡日粮中添加蛋氨酸铁或硫酸亚铁，前者使肉鸡的平均日增重提高了 5.38％，料肉比降低了1.17％。在蛋用公鸡日粮中添加 80 mg/kg 的蛋氨酸铁，其所产仔鸡的增重和内脏器官的发育明显优于对照组公鸡所产的仔鸡，同时21日龄和28日龄的体重比 对照组仔鸡分别提高了10.57％和 14.94％ (P＜0.05)。蛋鸡饲料 中加入适量有机铁比添加硫酸亚铁更有益于提高母鸡的产蛋率，并能显著降低破蛋率。

Amino acid chelated iron as animal iron supplement.

Effect of amino acid chelated iron on animal production

Adding ferrous glycine to piglet feed can increase average daily gain and decrease feed to meat ratio of piglet. Iron amino acid chelate can significantly improve the daily gain and feed utilization of growing-finishing pigs. Iron amino acid chelate can improve skin color and hair condition of fattening pigs. Compared with sows fed ferrous sulfate, sows fed the same level of amino acid iron from the first day of gestation to the weaning stage had a shorter interval of 0.4 d from weaning to estrus, and their weaned piglets had significantly improved body weight. The addition of amino acid iron to feed can promote the growth of piglets. Adding iron methionine to feed can significantly increase the growth rate of broilers and increase their daily gain. The average daily gain of broilers increased by 5.38% and the feed to meat ratio decreased by 1.17% when iron methionine or ferrous sulfate were added to broilers' diets. When 80 mg/kg iron methionine was added to the diet of laying hens, the weight gain and internal organ development of broilers were significantly better than those of control cocks, and the body weight of broilers at 21 and 28 days of age was 10.57% and 14.94% higher than that of control cocks (P < 0.05). Adding proper amount of organic iron into the feed of laying hens is more beneficial to increase the laying rate and reduce the breaking rate of eggs significantly than adding ferrous sulfate.
