The invention discloses a feed for specific pathogen-free (SPF) chicken in the growing period and a preparation method for the feed. The feed is characterized by being prepared from the following raw materials in part by weight: 570 to 590 parts of corn flour, 190 to 210 parts of bean pulp, 150 to 170 parts of wheat bran, 15 to 24 parts of fish meal, 0.5 to 1.5 parts of lysine with the purity of 98 percent, 1 to 2 parts of methionine with the purity of 98 percent, 5 to 15 parts of mountain flour, 10 to 20 parts of calcium hydrophosphate, 2 to 3 parts of table salt and 10 parts of premix. Compared with the traditional sterilization method, the invention has the advantages that: a Co60 radiation source is adopted for sterilization, and a radiation dose rate and radiation time are strictly limited. The feed for the SPF chicken, which is sterilized by the Co60 radiation source, has small loss of nutritional components, is well sterilized and low in cost, and is suitable for industrial production.
