Abstract: Various embodiments disclosed relate to methods of predicting neutral detergent fiber digestibility (NDFD) properties of a feedstuff sample. A method of predicting neutral detergent fiber digestibility (NDFD) properties of a feedstuff sample includes collecting a near-infrared spectrum of the feedstuff sample to provide NIR data of the feedstuff sample. The method also includes predicting NDFD of the sample at an elapsed time, NDFD rate of the sample, and/or NDFD extent of the sample from the NIR data using a NIR/NDFD calibration model. Various embodiments provide a method of developing the NIR/NDFD calibration model using in vitro gas production (IVGP). Various embodiments provide a method of predicting digestibility of the feedstuff sample for an animal at a rumen passage rate (eNDF).
