Calibration and cross-validation statistics of the NIRS results for the estimation of NDF (neutral detergent fiber), FN (fecal nitrogen), and NDF-N (nitrogen bound to fibers) content from wild rabbit (Oryctolagus cuniculus) fecal samples.

a Values refer to: derivative order, gap (number of data points over which derivation was computed), first smoothing (number of data points for spectral smoothing), and second smoothing (data points for second spectral smoothing), respectively.b Standard Normal Variate (SNV), Detrend (DT), Multiple Scatter Correction (MSC) transformationsAbbreviations: N, Number of spectra; R2, coefficient of determination for calibration; SEC, standard error of calibration; SECV, standard error of cross validation; SD, standard deviation; r2CV, coefficient of determination for cross validation; RPD, ratio SD of calibration data set to SECV; RER, ratio range (maximum-minimum) of calibration data set to SECV.Calibration and cross-validation statistics of the NIRS results for the estimation of NDF (neutral detergent fiber), FN (fecal nitrogen), and NDF-N (nitrogen bound to fibers) content from wild rabbit (Oryctolagus cuniculus) fecal samples.
