Abstract: Visible (Vis) and near infrared reflectance (NIR) spectroscopy were used to predict dry matter(DM), acid and neutral detergent fibre (ADFom and aNDFom), ash, crude protein (CP) and pHin wet whole maize (WWM) silage samples. Samples were analysed by reference methods andspectra collected using a NIR spectrophotometer in reflectance (400?2500 nm). Predictive equa-tions were developed using modified partial least squares (MPLS) with full cross validation usingraw spectra or second derivative. Two scatter corrections were also used, namely standard normalvariate and detrend (SNVD) and multiplicative scatter correction (MSC). Coefficient of determina-tion in calibrationR2caland standard error of cross validation (SECV) were 0.91 (SECV: 6.5 g kg?1DM) for CP, 0.85 (SECV: 27.4 g kg?1) for DM using SNVD, and 0.86 (SECV: 22.1 g kg?1DM) using raw spectra. Poor correlations between the reference methods and NIR werefound for aNDFom, ash, OMD and pH. It was concluded that NIR spectroscopy might be a suit-able method to predict DM, CP and ADFom on WWM silage samples with minimal sample preparation. |
