Use of NIRS for the prediction of the chemical composition of sainfoin Onobrychis viciifolia Scop.
Résumé
Sainfoin is a forage legume adapted to cool climates, thriving well on basic and dry soils. It is much appreciated by farmers due to its high palatability, high nutritional value and non bloating properties. Sainfoin herbage contains variable amounts of condensed tannins that are implied in its nutritional characteristics and confer anthelmintic properties. Thus, their precise quantification, along with others parameters of chemical composition becomes crucial. The use of NIR technology for this characterisation is particularly relevant, especially since huge numbers of sainfoin samples are being generated by the efforts under way to select accessions from different European conditions. The aim of this work is to evaluate the suitability of NIRS for predicting the chemical composition and the content of condensed tannins of a collection of sainfoin samples
