The present invention addresses the problem of developing a method for predicting the quality of meat and a method for predicting shipment times in the cattle fattening stage more specifically, a method for estimating, in the cattle fattening stage, shipment dates or BMS numbers, which influence the price of beef carcasses in markets. The inventors of the present invention discovered correlations between the contents of specific minerals contained in the coats of cattle and the quality of meat, as a result of diligently carrying out studies to solve said problem, revealing that, on the basis of the contents of the minerals, the quality of cattle meat or shipment times can be predicted in the latter stage of cattle fattening, thus demonstrating that the abovementioned problem can be solved.
