按原料来源不同,鱼饲料可以分为动物性和植物性两大类。鱼粉、肉骨粉以及血粉等饲料原料含有丰富的动物性蛋白质,由于这些蛋白质所含的氨基酸与鱼类生长所需的氨基酸相似,所以用这种蛋白质饲料原料生产的鱼料饲喂,鱼类不但吸收率高,而且还具有吸收快,对水质污染程度低等优点。 According to different sources of raw materials, fish feed can be divided into animal and plant two categories. Feed ingredients such as fishmeal, meat and bone meal, and blood meal are rich in animal proteins. Since these proteins contain amino acids that are similar to the amino acids that fish require for their growth, they are fed not only with fish protein from the protein feed material Absorption rate, but also has fast absorption, low water pollution and other advantages.
