The invention belongs to the field of dairy cow performance determination and milk quality detection, and particularly relates to an MIR rapid batch detection method for the content of lactoferrin in milk. In the aspect of selection of the characteristic wave bands, the applicant breaks through a common method for screening characteristics by using an algorithm, and uses a manual selection and multiple traversal method, so that more characteristic wave bands and wave points for modeling are finally selected, and the range is wide. According to the method, 437 characteristic wave points are screened out, and meanwhile, the spectrum MIR of the same milk sample measured for the second time is selected for modeling, so that the model accuracy of modeling of data measured for the first time of spectrum is improved. And finally, an optimal combination of a data preprocessing method and a model algorithm is screened out, optimal parameters are determined, and the accuracy of the model is improved. The method disclos
