In vivo nylon bag and two‐stage in vitro , digestion techniques were used to estimate dry‐matter digestibility of 159 forage samples involving Coastal bermudagrass ( Cynodon dactylon L. Pers.), Pensacola bahiagrass ( Paspalum notatum Flugge ), pearl millet ( Pennisetum typhoides (Burm.) Stapf and C.E. Hubb.), blue lupine ( Lupinus angustifolius L.), Desmodium uncinatum , and Dolichos lablab L. A highly significant correlation (r = .81, P < .01) was obtained between the two methods with all forages. The stem component of the pearl millet samples gave the lowest correlation between methods. Either method, when properly used, can be of valuable assistance in evaluating the quality of large numbers of forage samples.
