摘要

The feasibility of using near infrared reflectance spectroscopy (NIRS) for predicting metabolizable energy of meat and bone meal (MBM) for swine was investigated. Thirty-three MBM samples were analyzed for chemical composition and their metabolizable energy content was determined in metabolism assays. Near infrared reflectance spectroscopy calibrations were developed for gross and metabolizable energy of the samples. Coefficients of determination for calibration and cross-validation were greater for gross energy compared with metabolizable energy. Poorer prediction of metabolizable energy by NIRS may be due to sources of variation unaccounted for by NIRS. It was concluded that NIRS is feasible for predicting gross energy but not metabolizable energy of meat and bone meal.Digital Object Identifier http://dx.doi.org/10.4141/cjas2010-001
