The invention belongs to the field of dairy cow performance determination and milk quality detection, and discloses an intermediate infrared spectrum rapid batch detection method for saturated fatty acid in milk. In the aspect of selection of characteristic wave bands, a common method of screening characteristics by using an algorithm is broken through, and a manual selection and multi-time traversal method is used. And finally, selecting a characteristic wave band for modeling, particularly screening out an absorption area containing part of water, and proving that the accuracy of the model can be improved by increasing part of the water absorption wave band. The optimal preprocessing and algorithm combination established by the saturated fatty acid model is selected, the optimal parameters are determined, and the accuracy of the model is improved. Rapid, accurate and low-cost detection of the content of the saturated fatty acid in the raw milk is realized, and rapid batch detection is realized. 本发明属于奶牛性能测定和
