　　In the 1940s, dogs began to be used as experimental animals for research. Dogs are mainly used to study several diseases in experimental surgery, basic medicine, pharmacology, toxicology and biomedicine. The development of biomedicine 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 uses an expansion process. This article mainly studies the difference between the test values and formula values of protein, fat, amino acids, vitamins and trace elements in experimental dog food under certain puff conditions.

　　 How to calculate the combined value of each nutrient component in the experimental dog food formula based on the data in the "Chinese Feed Ingredients and Nutritional Value Table" (28th edition), and send the completed experimental dog food to the laboratory. . Results After squeezing out, the experimental dog food lost 6% of fat, histidine, lysine and methionine lost 8%, 6% and 2%, vitamin E, vitamin B2, niacin, choline and The loss rate of vitamin B6 was 29%, 65%, 46%, 1% and 81%. Conclusion Conclusion Under the conditions of the powder puff parameters set in this study, the loss of various nutrients in the experimental dog food is as shown in the results. Because the puff parameters are different, the effect on nutrition is also different, so it is recommended to adjust the formula according to the actual production situation.
