　　The experimental mouse feed contains 18%-20% protein, which can meet your needs. Rats prefer a high-sugar diet, so they can increase their sugar content appropriately. Mice are highly inbred animals and must maintain their biological characteristics and provide them with a corresponding diet according to the characteristics of different strains in order to be able to successfully conduct experiments. In the diet, 18% crude protein and 4%-8% crude fat, KMJCR, BALB/c, DBA/2 and other mouse strains have achieved satisfactory reproduction effects. Although there are few studies on the requirements of essential fatty acids in mice, lactating mice prefer a high-fat diet and therefore require a diet particularly rich in linoleic acid. Rats have high requirements for calcium, vitamin A and vitamin D, but they are also very sensitive to excess vitamin A. Excessive vitamin A can cause embryonic malformations in babies. Adding 50 mg of vitamin E per kilogram of feed will significantly increase the pregnancy rate and litter size of mice. Sterile mice also need to pay attention to vitamin K supplementation.
