Prediction of diet quality in Mongolian livestock with portable near infrared spectroscopy of feces
Monitoring the nutrition of grazing animals requires knowledge of forage quantity and quality.Selection by grazing animals,especially in rangeland environments, complicates the determination of diet quality.Near infrared reflectance spectroscopy (NIRS) of feces is a non‐invasive method for determining diet quality in livestock (Stuth et al 2003,Coates 1998, Landau et al 2006).Heretofore reported only in bench‐top laboratory settings,the technology has been recently adapted for application with portable instruments ( Tolleson and Stuth 2005 ).If successful,this adaptation to portable instruments will facilitate extension of the technology into remote areas and developing countries.The objective of this study was to evaluate the ability of portable fecal NIRS to determine dietary crude protein (CP) in forage fed Mongolian livestock.
