MBM。Representative ruminant concentrate supplement and MBM samples were collected, and 235 calibration samples and 152 external validation samples were prepared. The spectra were scanned from 400~2498nm. The effect of spectrum pretreatment methods and spectrum region on the calibration results was considered. The calibration equations were established by SIMCA (soft independent modeling of class analogies) and DPLS (discriminant partial least squares) respectively. For external validation set, the accurate discriminant rate of SIMCA method was 96.1%, and the accurate discriminant rate of DPLS method was 100%. Comparing with NIRS quantitative analysis model of MBM in ruminant concentrate supplement, NIRS discriminant analysis model can detect if ruminant concentrate supplement was adulterated with MBM or not.
