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

Abstract

The invention relates to a feed for SPF (Specific Pathogen Free) breeding female rabbits in a pregnant period. The feed comprises the following components in parts by weight: 190-210 parts of corn flour, 90-110 parts of corn gluten feed, 355-375 parts of alfalfa meal, 190-210 parts of wheat bran, 1-2 parts of methionine the content of which is 98%, 2-4 parts of lysine, 4-6 parts of mountain flour for feed, 13-15 parts of calcium hydrophosphate, 2.5-3.5 parts of table salt, and 10 parts of premix. The invention also discloses a preparation method of the feed. The method comprises the following operation steps of: respectively weighting the raw materials; blending the weighted raw materials; uniformly stirring and packaging the raw materials; and sterilizing the packaged raw materials. According to the invention, the feed is scientific and reasonable in formula; the SPF breeding female rabbits in the pregnant period fed by the feed are high in farrowing rate, and the cubs are high in birth litter weight; and by adopting Co60 radiation sterilization, the content loss of nutrient substances is small, 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 for pregnant SPF female 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] The gestation period of SPF female rabbits refers to the period from breeding pregnancy to delivery. The gestation period of rabbits is generally 29-35 days (average 31 days). The central task of feeding management during this period is t...
