[0025] A preparation method of sterile experimental mouse feed, comprising:

[0026] S1. Detect the content of each nutritional component in the pre-made experimental animal basal food.

[0027] Firstly, the raw materials for the preparation of common mouse food can be used to prepare experimental animal base food. For example, it can be selected in parts by weight: 40-43 parts of corn flour, 10-27 parts of bran, 28-30 parts of soybean meal, 0.1-0.3 part of salt, 0.9-1.1 part of bone meal and 0.9-1.1 part of lysine, mixed The experimental animal base food made by stirring evenly. The beans here refer to the by-products left after soybeans are extracted for oil. Experimental animal base food can also be purchased directly from the market.

[0028] Then the nutritional content of the pre-made experimental animal basal diet was tested.

[0029] S2, the following nutrient content is used as the nutrient content standard of the sterile experimental mouse feed:

[0030] 14-28IU...

Embodiment 1

[0045] The embodiment of the present invention provides a sterile experimental mouse feed and a preparation method thereof.

[0046] A preparation method of sterile experimental mouse feed, comprising:

[0047] Weigh 40kg of corn flour, 25kg of bran, 28kg of soybean meal, 0.1kg of salt, 0.9kg of bone meal and 0.9kg of lysine and mix them evenly to prepare the experimental animal base food.

[0048] Detecting various nutrients in the experimental animal basal food, the measured vitamin A content is 23IU / g, vitamin D content is 0.04IU / g, vitamin E content is 6IU / g, vitamin K3 content is 0.8mg / kg, vitamin B1 content is 10mg / kg, vitamin B2 content is 6mg / kg, vitamin B6 is 3mg / kg, niacin 62mg / kg, pantothenic acid 11mg / kg, folic acid 0.9mg / kg, biotin 0.23mg / kg, vitamin B12 0.04mg / kg, organic selenium 0.2mg / kg, organic zinc 15mg / kg.

[0049] Compare the nutrient components detected above with the nutrient content standards of the sterile experimental mouse feed mentioned in step S...

Embodiment 2

[0053] The embodiment of the present invention provides a sterile experimental mouse feed and a preparation method thereof.

[0054] A preparation method of sterile experimental mouse feed, comprising:

[0055] Weigh 43kg of corn flour, 10kg of bran, 30kg of soybean meal, 0.3kg of salt, 1.1kg of bone meal and 1.1kg of lysine and mix them evenly to prepare the experimental animal base food.

[0056] Various nutritional components in the experimental animal basal food were detected, and the vitamin A content was 13IU / g, the vitamin D content was 0.081U / g, the vitamin E content was 6.3IU / g, and the vitamin K3 content was 0.7mg / kg. Vitamin B1 content is 11mg / kg, vitamin B2 content is 7mg / kg, vitamin B6 is 6mg / kg, niacin 63mg / kg, pantothenic acid 25mg / kg, folic acid 0.3mg / kg, biotin 0.28mg / kg, vitamin B12 0.05 mg / kg, organic selenium 0.18mg / kg, organic zinc 7mg / kg.

[0057] Compare the nutrient components detected above with the nutrient content standards of the sterile experimen...

Abstract

The invention relates to the technical field of laboratory animal feed for biological medicine and provides feed for a sterile laboratory rat. The feed comprises components as follows: 14-28 IU / g vitamin A, 1.5-4.3 IU / g vitamin D, 120-240 IU / g vitamin E, 5-20 mg / kg vitamin K3, 13-26 mg / kg vitamin B1, 12-24 mg / kg vitamin B2, 12-24 mg / kg vitamin B6, 60-120 mg / kg nicotinic acid, 24-48 mg / kg pantothenic acid, 4-8 mg / kg folic acid, 0.2-0.4 mg / kg biotin and 0.03-0.06 mg / kg vitamin B12. A method for preparing the feed comprises steps as follows: detection of nutritional ingredients in base grains, addition of nutrient substances and granulation. The feed for the sterile laboratory rat is beneficial to growth of the sterile laboratory rat and rapid healing of wounds.

Description

technical field [0001] The invention relates to the technical field of experimental animal feed of biomedicine, in particular to a feed for sterile experimental mice and a preparation method thereof. Background technique [0002] The so-called germ-free animals refer to animals in which no living microorganisms and parasites can be detected. From a microbiological point of view, experimental animals usually have parasites inside and outside their bodies, as well as bacteria and viruses in their bodies, and it is difficult to rule out certain potential infectious diseases. In addition, the serum of ordinary experimental animals contains antibodies. Therefore, there will be various interferences in medical scientific research with common animals that coexist, and the experimental results are often inaccurate. Using sterile animals for experiments can overcome the shortcomings of common experiments and make the experimental results correct and reliable. Sterile animals are t...
