氨基酸螯合鐵（Amino acid chelated iron）對動物生產(chǎn)的影響

在仔豬飼料中添加甘氨酸亞鐵能提高仔豬的平均日增重，降低料肉比。氨基酸螯合鐵可明顯提高生長育肥豬的日增重和飼料利用率。氨基酸螯合鐵能夠改善育肥豬的膚色以及毛況。與喂給硫酸亞鐵的母豬相比，從妊娠期的第一天開始到仔豬斷奶階段喂給同水平氨基酸鐵的母豬斷奶至發(fā)情的間隔縮短0.4 d，且其哺育的斷奶仔豬體重明顯改善。飼料中添加氨基酸鐵有助于促進仔豬的生長。在飼料中添加蛋氨酸鐵能夠顯著提高肉雞的生長速度，提高它們的日增重。在肉仔雞日糧中添加蛋氨酸鐵或硫酸亞鐵，前者使肉雞的平均日增重提高了 5.38％，料肉比降低了1.17％。在蛋用公雞日糧中添加 80 mg/kg 的蛋氨酸鐵，其所產(chǎn)仔雞的增重和內(nèi)臟器官的發(fā)育明顯優(yōu)于對照組公雞所產(chǎn)的仔雞，同時21日齡和28日齡的體重比 對照組仔雞分別提高了10.57％和 14.94％ (P＜0.05)。蛋雞飼料 中加入適量有機鐵比添加硫酸亞鐵更有益于提高母雞的產(chǎn)蛋率，并能顯著降低破蛋率。

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.
