| Abstract: | Analysis of fishmeal concentrations in feedstuff is critical to quality control and ingredient statement of commercial feed. Near-infrared reflectance spectroscopy (NIRS) determination for fishmeal was established through the spectral data processed by mean center, normalization, Savitzky–Golay first, partial least square 1 and cross validation. The coefficient of determination (R 2) of NIRS calibration model, the standard error estimated by cross validation (SECV) were 0.9554 and 0.9541, respectively. At the same time, the coefficient of determination of validation was 0.9867. Moreover, it has been proven to be directly correlated between the fishmeal spectra and the loading of the second principal components, and the coefficient of determination of the spectra of the calibration model. These results support our theory that the NIRS method constructed in our study could be used to quantify fishmeal in compound feeds. |
