　　Purpose: Dogs are one of the earliest domesticated animals. In the 1940s, dogs began to be used as experimental animals for research. Dogs are mainly used for research on various diseases such as experimental surgery, basic medicine, pharmacology, toxicology, and biomedicine. Biomedical development is very important. Providing a stable prescription and standardized diet for experimental dogs is an important part of improving experimental science. At present, the production of experimental dog food mainly adopts the puffing process. This article mainly discusses the difference between the experimental dog food protein, fat, amino acid, vitamin, trace element detection under certain puff conditions and the prescription value.

　　Method: How to calculate the compound value of each nutrient component in the experimental dog food formula according to the data in the "China Feed Ingredients and Nutritional Value Table" (28th edition), and send the completed experimental dog food to the laboratory.

　　Result: After expanding the experimental dog food, the fat loss decreased by 6? Histidine, lysine and methionine were reduced by 8? 6? 2? Vitamin E, vitamin B2, niacin, choline and vitamin B6 were lost. The percentages were 29%, 65%, 46%, 81%.

　　Conclusion: Under the conditions of the puff parameters set in this study, the loss of various nutrients in the experimental dog food is as shown in the results. Due to the different parameters of the puffs, the effect on the nutritional ingredients is also different, so it is recommended that colleagues adjust the ration appropriately according to the actual production situation.
