Abstract

•
Determining the quality of grazed forage remains a challenge for nutritional modeling and monitoring in livestock.
•
One method used to accomplish this task has been near-infrared spectroscopy of feces (FNIRS) combined with the Nutritional Balance Analyzer Model (Nutbal).
•
Users of the FNIRS-Nutbal system in the Edwards Plateau of Texas have observed inaccurate predictions of diet quality on rangelands.
•
Application of a regional-specific FNIRS calibration improved the estimation of grazing animal diet quality in this region.
•
Nutritional monitoring of beef cows grazing Edwards Plateau rangeland via the FNIRS-Nutbal system was accurate enough (± 0.5 body condition score, 80% occurrence) to inform management decisions, but incorrect predictions of animal performance did occur.
