蛋氨基酸锰对蛋鸡生产性能的影响

Effect of Manganese Methionine on Layer Performance

[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。

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 ng/kg of manganese methionine respectively for the feeding experiment, the result shwed 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 ng/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.
