bibo:abstract
  • Near-infrared reflectance spectroscopy(NIRS) has become increasingly used as a rapid, accurate method of evaluating some chemical composition in cereals and dried forages. The predictive accuracy of NIRS relies heavily upon obtaining a good calibration set which represents the variation in the main population, accurate laboratory analyses and the application of the best mathematical procedures. Dried finely chopped samples(n=96) were scanned at 2nm intervals over the wavelength range 400-2500nm and the optical data recorded as log 1/Reflectance(log 1/R). Modified partial least squares(MPLS) regression was applied to scatter-corrected spectra(SNV and detrend). Calibration models for NIRS measurements gave multivariate correlation coefficients of determination(R²) and standard errors of calibration(SEC) of 0.84(SEC 0.28), 0.94(SEC 1.74,) 0.91(SEC 0.74) and 0.95(SEC 0.14) for content of dry matter(DM), neutral detergent fiber(NDF), acid detergent fiber(ADF) and crude protein(CP) on a dry basis respectively. The standard error of prediction(SEP) on the validation set(n=36) was used in comparisons of prediction accuracy. The SEP value was 0.33(DM), 1.79(NDF), 0.7(ADF) and 0.1%(CP), respectively. The relative ability of NIRS to predict chemical composition was very good for CP, NDF and ADF, and low for DM. This research should be useful in rapid analysis of forage quality for research and industry. (rdf:langString) (en)
