Central Oklahoma native range forage samples were collected from April through Decem-
ber to determine seasonal compositional changes and the relationship or correlation of in
vivo nylon bag dry matter digestibility (DMD) to nylon bag organic matter digestibility (OMD)
Forage samples were "hand separated" into live and dead vegetation during May, June,
July and September (growing season). During the non-growing season (April, October, No-
vember and December) samples were identified as standing dead vegetation (STDV). 
Samples (ground through 2 mm screen) weihing 3 g were placed in 100 mesh nylon bags
and incubated in the rumen for 48 hr in fistulated steers grazing native range. The DMD
and OMD correlation coefficients ranged from .9432 to .9941 even though differences in ash digestion were recorded. the data obtained suggest that either DMD or OMD may be
used about equally well in determininf forage quality.
