Feed for SPF male rabbit mating period and preparation method thereof

Abstract

The invention relates to feed for an SPF (Specific pathogen Free) male rabbit mating period. The feed comprises the following raw materials in parts by weight: 180-200 parts of maize powder, 130-150 parts of bean pulp, 210-230 parts of wheat bran, 400-420 parts of alfalfa meal, 0.5-1.5 parts of 98% of methionine, 1.5-2.5 parts of lysine, 9-11 parts of feed rock flour, 14-16 parts of calcium hydrophosphate, 4.5-5.5 parts of salt and 10 parts of premix. The invention further discloses a preparation method for the feed. The preparation method comprises the steps as follows: weighing the raw materials respectively; blending the weighed raw materials; uniformly mixing and packaging; and sterilizing the packaged raw materials. The feed formula is scientific and reasonable, the SPF male rabbit fed with the feed during the mating period is high in weight increment amount and high in survival rate, and the feed is subjected to Co60 irradiation sterilization, so that the nutrient loss is low, and the feed is easy to store.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a feed used in the mating period of SPF male rabbits and a preparation method thereof. Background technique [0002] In addition to being used in medicine, pharmacy and biological research, laboratory rabbits are also widely used in the pharmaceutical industry. The quality of experimental rabbits directly affects the accuracy of experimental results and the quality of medicines, and is related to people's health. At present, SPF (Specific pathogen Free, no specific pathogen) rabbit breeding population has been established abroad, and the commercialization of supply has been realized, but only a few units and regions in China can reach the SPF level. [0003] SPF male rabbits must be well-developed, physically strong, and have a strong libido in order to complete the mating task. "Male rabbits are good, a good batch is good, female rabbits are good, and a litter is good." The bree...

Problems solved by technology

[0007] At present, the method used in the world to kill specific pathogens in SPF rabbit feed is to use high-pressure steam sterilization, that is, to pack the finished feed products and wrap them with specific plastic sheets, 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. Can be used, this method is time-consuming, laborious, waste of resources, but also need to use steam boilers and waste a lot of coal

During the combustion of coal, a large amount of waste gas such as carbon dioxide and pollutants such as dust will be produced, which will cause great pressure and pollution to the environment. Causes a large loss of nutrients, and more troubles lead to dampness of the feed and shortening of the storage time of the feed due to the increase in moisture content, and even lead to the growth of mold in the feed and the production of mycotoxins in the high temperature season
