Description
Faecal near infrared spectroscopy (FNIRS) has been used to predict dietary crude protein (CP) and digestible organic matter (DOM) in grazing animals (Stuth et al., 2003, Coates 2000). Development of robust FNIRS calibrations can be time consuming and costly, thus hindering the application of FNIRS in developing countries. Delivery of samples to central laboratory facilities is dependant upon adequate transportation infrastructure. A "take the laboratory to the samples" approach is being tested in Mongolia using a portable FNIRS laboratory (Stuth et al,. 2004). The initial step in this process is to duplicate the performance of a static laboratory procedure with portable equipment. The objective of this study was to determine the effectiveness of re-creating existing FNIRS diet quality calibration models on a portable spectrometer.
