Immunodeficiency mouse feed and preparation method thereof

Abstract

The invention relates to feed for experimental mice and discloses feed capable of improving immunity of immunodeficiency mice and a preparation method thereof. The feed is composed of, by weight, 20-40% of corn, 10-20% of rice, 10-20% of wheat, 10-20% of flour, 3-6% of soybean protein isolate, 3-6% of fermented soybean meal, 0.2-0.6% of beer yeast powder, 5-10% of expanded soybean, 5-10% of Peru fish meal, 2-5% of chicken meal, 2-5% of premix, 0.5-2% of calcium carbonate and 2-4% of soybean oil. Organic zinc and organic selenium which are mineral substance are added into the immunodeficiency mouse feed, so that resistance of the experimental mice is improved; the immunodeficiency mouse feed is high in bioavailability and comprehensive and balanced in nutrition, survival time of the experimental mice is prolonged while immunodeficiency state unique to the same is maintained, reproductive rate of the experimental mice is increased, and death rate is lowered.

Description

Technical field [0001] The invention relates to a feed for experimental mice, in particular to a feed capable of improving the immunity of immunodeficiency mice and a preparation method thereof. Background technique [0002] Immune-deficient mice are a common type of experimental mice. This kind of mice has no immune system and has low immunity. Their health and reproduction and breeding conditions are very easily affected by diet and breeding environment. Ordinary feed is difficult to satisfy such experimental mice. Special requirements. [0003] At present, although there is a national standard for experimental rat food in China, its standard requirements are relatively low. Therefore, the production of experimental rat food is uneven, with a wide variety of varieties and not very specific. The quality of raw materials for domestic laboratory rat feed is generally not high, and the content of pesticide residues and heavy metals is higher than the average level of existing foreig...

AI Technical Summary

Problems solved by technology

[0002] Immunodeficiency mice are a common type of experimental mice. This kind of mice has no immune system and low resistance. Their health and reproduction are very easily affected by diet and feeding environment. It is difficult for ordinary feed to satisfy this type of experimental mice. special requirements

[0003] At present, although there are national standards for experimental mouse food in China, the standard requirements are relatively low, so the production of experimental mouse food is uneven, there are many types, and the pertinence is not strong

The quality of domestic experimental mouse feed production raw materials is generally not high, and the content of pesticide residues and heavy metals is higher than the average level of existing foreign products.

For experimental mice with immunodeficiency, the survival period is short, the breeding survival rate is low or the quality is low due to the high content of pesticide residues and heavy metals in the feed, which affects the research of life sciences, or because the selection of feed raw materials is not appropriate and the processing is not fine. , and affect the digestion and absorption of immunodeficiency mice, resulting in their inability to smoothly and comprehensively absorb the nutrients they need, which is not conducive to their normal growth and reproduction
