To determine the effect of palm kernel meal on total and cellulolytic bacteria and cecal fermentative indicators, 12 broilers were used in a completely randomized design with four treatments: control and inclusion of 5, 10 and 15 % of palm kernel meal. The concentrations of total and cellulolytic bacteria, dry matter, pH and ammonia were determined. Total bacteria increased from 10 % with respect to the 5% inclusion of palm kernel meal (26.22, 22.06 vs. 7.06 x 1011 cfu.g-1). Cellulolytic were more, with 5% and less with 15 % in relation to control (27.44, 9.11 vs. 17.78 x 106 ufc. g-1). Dry matter decreased at 15 %, pH was higher at 10 % and NH3 was reduced as the percentage of meal increased. It is concluded that the inclusion of 15 % of palm kernel meal maintains the concentration of total bacteria and reduces cellulolytic bacteria, as well as dry matter and ammonia in the cecum of broilers.
