Utilisation of near Infrared spectroscopy to optimise productivity of grazing animals in the Western Australian rangelands
The use of Near Infrared Spectroscopy (NIRS) to assess the quality of animal feed (dry matter,crude protein,NDF and ADF) is a well established technique and its usefulness as a predictive tool may match or exceed that of traditional wet chemistry (1,2).More recently faecal NIRS ( f NIRS) has been developed to measure various dietary indicators in ruminants (3,4,5).Up until now it has not been possible to calibrate the technique for universal feeds,with relevant calibrations being developed for a limited number of browse and grass species.It has been necessary to recalibrate the technique for each pasture type.However,our f NIRS calibrations are able to predict the nutritional attributes of mixed diets and therefore will have more generic application.
