This research was designed to develop a set
of prediction equations to measure nutrient
composition of Kansas sorghum silages using
both a portable and a research type near-infrared
spectrometer (NIRS). A robust set of
equations for dry matter, crude protein, neutral
detergent fiber, and acid detergent fiber was
developed for a wide range of sorghum
phenotypes . NIRS analysis of sorghum silages
is feasible with both a tilting filter (portable) and
research instrument with a grating monochrometer.
