Esophageal-fistula forage samples were colected in screen-bottomed bags from cows gra-
zing post oak savannah range, and in both screen-bottomed and watertight bagas from
Coastal bermudagrass pastures. These esophageal-fistula samples and hand-plucked Co-
astal bermudagrass samples were dried by freeze-drying, oven-drying (60 c) and air-drying
methods. Freeze-dried esophageal samples were significantly higher (P<.05) in total nons-
tructural carbohydrates (TNC) and hemicellulose, but lower in acid detergent lignin than
oven- and air-dried samples. Freeze-dried hand-plucked bermudagrass was higher in TNC
than oven- or air-dried samples; however, no significant changes in crude protein and cel-
lulose were detected among methods of drying. Compared with freeze-drying, organic mat-
ter (OM) losses from oven- and air-drying ranged from 9 to 13% for esophageal-fistula sam-
ples and from 4 to 5% for hand-plucked Coastal bermudagrass. Higher OM losses from fis-
tula samples than hand-plucked samples might the attributed to their higher moisture con-
tent, longer drying time, and plant enzymatic activity. Accurate comparisons of the three
drying methods were possible only when the data were expressed as grams of constituent
remaining per 100 g of original OM. Delaying freezing of esophageal samples for 4 hr did
not alter chemical composition of samples. Samples from screen-bottom collection bags,
as compared with watertight bags, were higher in crude protein and lignin, but lower in
TNC. This may be a result of leaching. MenosEsophageal-fistula forage samples were colected in screen-bottomed bags from cows gra-
