Description
The forage energetic value determination has always been and remains a important issue. It consists in predicting the Organic Matter Digestibility (OMD). Measuring In Vivo OMD on animals is time and money consuming. To predict OMD in laboratory, different chemical, microbiological and enzymatic methods are used. The articles published on the use of Near InfraRed Spectrometry (NIRS) indicate that this method can improve OMD determination efficiently (Norris, 1983; Shenk, 1977; Biston, 1981, 1984, 1985, 1988). The research work carried out in the Station de Haute Belgique in collaboration with INRA in Theix, has defined the efficiency of these technics for OMD prediction. This article deals with the most relevant results and new approaches for analyzing spectral data.
