饲用复合氨基酸代替鱼粉饲喂29～44周龄罗曼蛋鸡的试验

Experiment of Lohman Brown Commercial layers fed hy Compound Amino Acids substitute for Fish Meal.

饲用复合氮基酸代替鱼粉饲喂29～44周龄罗曼蛋鸡的试验结果表明,它代替一半鱼粉组,平均蛋重、产蛋率与鱼粉组相近;每生产1公斤蛋,耗料比鱼粉组低130克,需料成本少0.16元;鸡蛋品质无差别,而蛋白品质优于鱼粉组;鸡蛋中氨基酸总含量虽低于鱼粉组,但人体所需的必需氨基酸—赖氨酸、苯丙氨酸高于鱼粉组。可见,饲用复合氨基酸代替一半鱼粉饲喂蛋鸡是可行的。

The experiments, in which the Lohman Brown Commercial layers are fed by compound amino acids substitute of fish meal, have showed that: HSG's average egg weight and rate of egg production are close to FMG's, Its feed conversion of experimenting period is 2.29,and better than FMG's, Its feed cost per kilogram egg goes down 0.17 yuan compared with FMG's, It's egg guilty is similar to FMG's, Its Haught unit is better than FMG's. From above, we learn that it is possible that compound amino acides for feed replace the fifty percent of fisb meal
