兔饲粮中的限制性氨基酸有蛋氨酸、赖氨酸、精氨酸。但是,兔以植物性蛋白质饲料为主要来源时,一般蛋氨酸不足,常常添加蛋白质含量高的鱼粉,然而鱼粉的价格比较贵,因此,我们根据氨基酸平衡的原理,采用豆饼添加蛋氨酸代替鱼粉饲喂新西兰兔试验,同时为了降低生产成本,提高经济效益, Restricted amino acids in rabbit diets are methionine, lysine and arginine. However, due to the lack of methionine and the high protein content of fish meal, rabbits are often more expensive than fish meal because of the lack of methionine. Therefore, based on the principle of amino acid balance, we used methionine instead of fish meal to feed New Zealand Rabbit test, at the same time in order to reduce production costs and improve economic efficiency,
