PROBLEM TO BE SOLVED: To provide a method for calculating an intestinal age of a pet and a method for determining an intestinal age calculation formula for estimating the intestinal age from the distribution of bacteria. SOLUTION: Obtaining bacterial flora data in a healthy individual, selecting a bacterium having a high correlation with the actual age based on the distribution amount of each bacterium, and using the distributed amount of the selected bacterium as an argument. Regression analysis creates the first equation for calculating the intermediate intestinal age based on the extraction of the main component by compression, the main component obtained by dimensional compression, and the distribution amount of the selected bacteria. .. The second formula for predicting the actual age from the intermediate intestinal age calculated from the prepared first formula is prepared by regression analysis. A method for determining a pet's intestinal age calculation formula for creating a second formula including a constant for reducing an error of the prediction model itself based on the first formula and the second formula.
