Description
High correlations have been reported between data from near infrared reflectance spectroscopy (NIRS) and the protein and fiber contents, as well as the intake and digestibility, of forages (Norris et al., 1976). The finding in some studies that sample sets for calibration and unknown samples should be restricted to relatively narrow populations (Marten et al., 1983) has limited the usefulness of NIRS. However, in experiments with legumes, correlations with NIRS data were almost as good across species as among species (Marten et al., 1984). The experiment reported here was conducted to discover quantitative relationships between NIRS spectra and chemical composition, digestibility, intake and body weight from 20 forages representing 5 plant cultivars/species grown at 4 locations.
