In a compeletely randomized design, with factorial arrangment (3x3, n=5), the effect of 5, 10, 15 percent molasses with 0.5, 1.0 and 1.5 percent urea were assessed on in vitro digestibility and fermentibility of roughage based diets incubated with buffalo rumen liqure. The in vitro digestibility and ruminal fermentability were measured based on the gas test method, where the samples incubated in buffaloes rumen liqure. Irrespective of urea, the digestibility was not affected by the levels of molasses. Dry matter and organic matter digestibilities were 66.1 and 65.2; 65.5 and 64.1; 65.7 and 64 percent for the diets contained 5, 10 and 15 percent molasses respectively that were not staitistically different. For the simple effect of urea, the dry matter and organic matter digestibilities were 65.5 and 64.2; 65.4 and 64.0; 66.6 and 65.2 percent for treatmets 1, 2 and 3 respectively that were not significantly different. No interaction effects were found between urea and molasses on the digestibility of the diets. The gas production was significant (p<0.05) different between the treatments, after 12 and 24h of incubation, but no statistically variation was found for the other times of incubation.
