Forage protein characteristics in four
grasses were evaluated by the nylon bag
method. All of the forages used (Bermudagrass
hay, brome hay, forage sorghum hay, and
prairie hay) were of relatively low quality,
except the Bermudagrass, which was of average
quality. The forages differed in the size of
different protein fractions and in the rate and
extent of protein degradation. Predicted extent
of ruminal protein degradation (i.e., ruminal
protein availability) was lowest for prairie hay,
intermediate for Bermudagrass and forage
sorghum hay, and highest for the brome hay.
