Problems solved by technology

[0005] At present, most of the methods used in the world to kill specific pathogens in SPF breeder feed are high-pressure steam sterilization, which is to pack the finished feed products with specific plastic cloth and put them into high-pressure chambers. , put in water vapor to make the pressure reach 4.5 standard atmospheric pressure, the temperature reaches above 120 degrees Celsius, and keep the water vapor flowing, the sterilization time is more than 45 minutes, and then take samples for inspection under special circumstances to ensure that the feed does not contain specific pathogens. It can be used, but this method is time-consuming, laborious and wastes resources, and it also needs steam boilers and wastes a lot of coal. During the combustion of coal, a large amount of waste gas such as carbon dioxide and dust and other pollutants will be produced, which will cause great damage to the environment. Pressure and pollution, at the same time, in the process of using water steam autoclaving to kill specific pathogens, it also causes a large loss of nutrients. Shorter storage times, even in hot seasons lead to mold growth and mycotoxin production in the feed

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...
