This study was conducted to compare some digestible properties between Pennisetum purpureum (Napier) and Brachiaria humidicola (Humidicola) grasses. The digestibility was obtained by conducting a 5-day digestibility experiment based on total-faeces-collection method. Two goats were used for each digestibility experiment. Napier and Humidicola grasses were fed fresh to the animals every day, and the forages were weighed before feeding to the goats. The feed residues and their faeces were collected the next day and weighed to estimate the amount of feed intake as well as the faeces. The samples of fresh feed, feed residues and faeces were brought to thelaboratory for dry matter (DM) analysis. The DM digestibility for Napier and Humidicola were 87.89 and 87.31%, respectively. The DM content of Napier was a little lower than Humidicola grass, which was 35.91% and 49.04%, respectively. Although the results were not statistically significant, they were acceptable in view of the preliminary nature of this study. Further studies should be conducted by prolonging the time period according to the standard methodology of digestibility and by using a higher number of goats per treatment to obtain better distribution of means.
