Abstract

The invention discloses a feed used in the later laying peak period of SPF (specific pathogen free) breeding hens and a preparation method thereof. The feed is characterized by comprising the following raw materials in parts by weight: 620-640 parts of corn meal, 200-220 parts of bean pulp, 25-35 parts of wheat bran, 15-25 parts of fish meal, 1-2 parts of 98% of methionine, 70-90 parts of limestone meal, 10-14 parts of calcium hydrophosphate, 2.5-3.5 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 has low nutrient losses, good sterilization effect and low cost and is suitable for industrial production.

Description

technical field

[0001] The invention relates to a chicken feed and a preparation method thereof, in particular to a feed used for SPF breeder chickens at the late stage of laying eggs and a preparation method thereof, belonging to the field of feed processing. Background technique

[0002] There are millions of agricultural scientific research and technical extension personnel all over the world engaged in the research and production of SPF egg sources required for the manufacture of animal vaccines, but they are faced with the dilemma of being unable to find reasonable and effective technologies to prevent SPF chicken breeding failures.

[0003] It is not possible to use conventional feeding methods to produce SPF eggs. We know that the breeding of SPF chickens requires specific houses, equipment and feed. SPF chicken feed has several special processing treatments before feeding. The purpose is to kill SPF chickens. Specific pathogens in the feed, and then transported to th...
