Abstract

The invention discloses a feed for specific pathogen-free (SPF) chicken in the peak laying period (daily age of 127-420) and a preparation method for the feed. The feed is characterized by being prepared from the following raw materials in part by weight: 620 to 640 parts of corn flour, 190 to 210 parts of bean pulp, 15 to 24 parts of wheat bran, 35 to 45 parts of fish meal, 1 to 2 parts of methionine with the purity of 98 percent, 70 to 90 parts of mountain flour, 10 to 14 parts of calcium hydrophosphate, 2.5 to 3.5 parts of table salt and 10 parts of premix. Different from 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.
