Abstract
This study was conducted to determine rumen-modifying properties of ripe Acacia pod meal (APM) in local cattle in terms of changes in bacterial diversity and total volatile fatty acid concentration and to determine the effect of APM on the growth performance of cattle. Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) was used to determine the changes in the bacterial diversity in rumen fluid samples from animals fed with Napier, Napier-Rice bran-Copra meal mix and Napier-APM mix. Results showed that feeding APM influenced the proliferation of Selenomonas ruminantium and Clostridium straminisolvens and disappearance of Olsenella profuse, Acetitomaculum ruminis and Treponema saccharophilum. Total volatile fatty acid (TVFA) of rumen fluid was not significantly different among the treatments. Feeding of APM to growing heifers resulted in significantly lower (P<0.05) average daily gain (ADG) compared to those fed without APM. ADG was observed to decrease as amount of APM was increased. Cattle fed without APM had significantly better feed conversion ratio (FCR) than those fed with APM.
