摘要
在断奶仔猪日粮中添加蛋氮酸铁进行了两次饲养试验.试验结果表明,在35～80日龄断奶仔猪日粮中添加60ppm 蛋氨酸铁,试验组和对照组的日增重分别为496～566和439～514克/天,料肉比分别为1.98～2.18∶1和2.12～2.45∶1。添加蛋氨酸铁后,生长猪的日增重、饲料效率和经济效率分别提高9.99～12.98%,6.60～10.61%和18.16～28.47%.
Adding Iron-mcthionin chelated (MFc) to the growth ration,two feeding tests have been conducted with weanling pigs.The test results show that adding 60ppm Fe as MFe to the growth ration,the daily gains of treatment growp is 496～566g/day,while the control growp is 439～514 g/day.The feed conversion in the treatment group is 1.98～2.18:1,and in the control group is 2.12～2.45:1.The grower's day gain,feed efficiency,and economy of gain is increased.9.99～12.98%,6.60～10.61% and 18.16～28.47%.
