Problems solved by technology

Due to the special physiological characteristics of immunodeficiency mice, their feeding and breeding are more difficult than conventional strains, and there are common problems such as low reproductive ability, fast replacement of breed mice, and weak constitution of young mice. This is also a common problem faced by manufacturers. How to improve immunity The reproductive rate and animal quality of defective animals restrict the development of manufacturers, and directly affect the research of tumor and immunology

Abstract

The invention discloses feed applied to immunodeficient mice. The feed is prepared from the following components in parts by mass: 10-20 parts of wheat middlings, 2-10 parts of bran, 35-45 parts of expended maize, 17-25 parts of soybean meal, 5-11 parts of fish meal, 1-4 parts of maize protein powder, 0.5-1.5 parts of beer yeast, 1-4 parts of vegetable oil, 0.3-0.6 part of choline chloride, 0.1-0.5 part of methionine, 0.1-0.5 part of lysine, 3-5 parts of mineral salt premix and 0.1-0.2 part of vitamin premix. Through frequent adjustment of the formula and the process, a formula and a preparation process of the feed which is balanced in nutrition and high in palatability, and is applicable to the immunodeficient mice are determined; through the optimization of the raw materials and the adoption of the special ratio and the production process, complex feed capable of meeting requirements on growth, gestation and lactation of the immunodeficient mice is provided.

Description

technical field [0001] The invention relates to the field of experimental animal nutrition, in particular to a feed for immunodeficiency mice and a preparation process thereof. Background technique [0002] Tumor and immunology research requires a large number of immunodeficiency mice. Currently, the main strains on the market are BALB / cAn-nu / nu Mice, NOD SCID Mice, SCID Mice, NSG, etc., and these strains have different degrees of immunodeficiency. For the user, the higher the degree of immunodeficiency, the higher the survival rate of tumor inoculation, but at the same time the weaker the body, the lower the resistance and reproduction rate. Due to the special physiological characteristics of immunodeficiency mice, their feeding and breeding are more difficult than conventional strains, and there are common problems such as low reproductive ability, fast replacement of breed mice, and weak constitution of young mice. This is also a common problem faced by manufacturers. How...
