- Method / resource The optimum NIRS equation gave a calibration error of 14.4 g kg −1.
- Observation Selected equations had three wavelength pairs within 40 nm.
- Method / resource Forced wavelength equations had validation errors no different from the original equation.
- Recommendation The authors concluded wavelength pairs were necessary for spectral slope differences.
- Method / resource Recalibration with pasture and esophageal samples improved SEC to 9.5 g kg −1.
- Method / resource Recalibration with pasture and esophageal samples improved SEP to 9.8 g kg −1.
- Method / resource Recalibration with fecal samples improved SEC to 10.6 g kg −1.
- Method / resource Recalibration with fecal samples improved SEP to 12.7 g kg −1.
