Application of alpha-ketoglutaric acid and use method thereof

The present invention relates to an application of alpha-ketoglutaric acid and a use method thereof, and aims to solve the technical problems that currently, phosphorus deposition rate is low in a complete compound feed for aquatic animals. The alpha-ketoglutaric acid is used as a feed additive for improving the phosphorus deposition rate of the aquatic animals. The use method is as follows: the alpha-ketoglutaric acid is added into the raw materials of the complete compound feed and then the content of the calcium dihydrogen phosphate is reduced. The alpha-ketoglutaric acid is added into the raw materials of the complete compound feed and the content of the calcium dihydrogen phosphate is reduced, which improves the phosphorus deposition rate of the aquatic animals, also significantly increases the weight gain rate, phosphorus content and protein efficiency of the aquatic animals, and also reduces the environmental pollution caused by the calcium dihydrogen phosphate. The application and the use method provi
