In vitro digestibility of oil palm frond treated by local microorganism (MOL)

Oil palm frond is by product from oil palm plantation and were found in large quantity in Indonesia. This research aims to examine the ability of local microorganisms and buffalo rumen isolates in improving the digestibility of dry matter and organic matter in vitro of oil palm frond. The research used experimental method with four treatments and three replications. The treatments were given: Oil palms without treatment (P0); Starbio (P2); Aspergillus niger + Saccharomyces cerevisiae (P3); Aspergillus niger + Saccharomyces cerevisiae + Isolate of buffalo rumen bacteria (P4). The results showed that the fermented Oil Palm Frond had higher (P< 0.05) DMD and OMD than control. The addition of Aspergillus niger and Saccharomyces cerevisiae plus buffalo rumen bacterial isolates had higher (P< 0.05) DMD and OMD than other treatments. It can be concluded that the utilisation of MOL can improve the digestibility of oil palm frond in vitro.
