Description
There are two principal means for assessing the quality of grazing ruminant diets, analysis of extrusa from esophageally fistulated animals or indirect estimates from fecal analysis. Wet chemistry methods are well documented for the former but have proven to be of limited value regarding the latter. It is the purpose of this research to determine the suitability of near infrared spectroscopy (NIRS) for estimating diet crude protein (%) and organic matter digestibility (%) directly from extrusa and indirectly from feces.
