The feed is characterized by comprising the following raw materials in parts by weight: 590-610 parts of corn meal, 280-320 parts of bean pulp, 25-35 parts of wheat bran, 25-35 parts of fish meal, 0.5-1.5 parts of 98% of lysine, 1-2 parts of 98% of methionine,5-15 parts of limestone meal, 10-20 parts of calcium hydrophosphate, 2-3 parts of salt and 10 parts of premix. Compared with the traditional sterilization method, the preparation method is characterized by adopting a Co60 ray source for radiation sterilization and strictly limiting the radiation dose rate and radiation time. The feed subjected to radiation sterilization of the Co60 ray source haslow nutrient losses, good sterilization effect and low cost and is suitable for industrial production.
