Discussion

Research demonstrates a novel MIR model for udder health status in dairy cattle, highlighting its effectiveness for mastitis diagnosis.

The developed MIR diagnostic model identifies healthy and mastitis-affected cattle effectively, achieving an AUC of 0.80 in the test set.
Employing a difference spectral preprocessing method and a Random Forest modeling algorithm enabled precise udder health status evaluation.
Data from 2288 milk samples was analyzed, reflecting a comprehensive approach to udder health assessment in dairy farms.
Improving the model's diagnostic precision and versatility will require gathering more diverse samples in future research.

Ren et al. (2025) studied this question.
