蛋氨基酸锰对蛋鸡生产性能的影响

目的]探究蛋氨基酸锰对蛋鸡生产性能的影响。方法]将25周龄的商品蛋鸡400只随机分成5组,待分组产蛋稳定后,在饲料中分别添加0、20、40、60、80 mg/kg蛋氨基酸锰进行饲喂试验。结果]结果表明,添加了蛋氨基酸锰的4个试验组饲料转化率和产蛋率均高于对照组,当添加量为60 mg/kg时,饲料转化率和经济效益最佳。结论]用蛋氨基酸锰作商品蛋鸡的饲料添加剂是可行的,具有较高的开发利用价值。

Effect of Manganese Methionine on Layer Performance

The experiment was designed to explore the effect of manganese methionine of layer performance.Four hundred commercial layers of 25 weeks of age were randomly divided into 5 groups.When egg laying was stabled,the diets were added 0,20,40,60,80 mg/kg of manganese methionine respectively for the feeding experiment.The result showed that the 4 experiment groups that were added with manganese methionine had higher feed conversion rate and egg laying rate than the control group.When the diet was added with 60 mg/kg,the feed conversion rate and economic benefit were the optimal.It is feasible to use manganese methionine as the commercial additive for layers,with a fairly high development utilization value.
