Abstract

Abstract: This study was conducted to determine the effect of acacia pod meal (APM) on the rumen fluid cellulolytic activity in growing and mature cattle. The 18 growing heifers were randomly assigned to 3 dietary treatments and the 3 fistulated mature cattle were used following 3x3 Latin Square Design (LSD). All animals were fed dry matter (DM) equivalent to 3% of the live weight (LW). The 3 dietary treatments were 1) 100% Napier grass (NG) 2) 70% Napier grass, 30% concentrate mix (NC) and 3) 70% Napier grass, 30% Acacia pod meal (NA). Rumen fluid samples were subjected to in vitro cellulolytic assay using DNS (3,5- dinitrosalycylic acid) method. Urine samples were analyzed for allantoin method to estimate microbial protein production. Results show that rumen fluid cellulolytic activity and microbial protein production were not significantly different among treatments. Feeding APM in growing heifers significantly reduced ADG and FCR. In mature cattle, no significant differences in cellulolytic activity and microbial protein production were observed. Acacia pod meal can therefore be used in concentrate mixture for mature cattle.
