Physical, chemical and in vitro digestibility quality of oil palm midrib fermented by Phanerochaete chrysosporium

Abstract

Oil palm midrib has potential to be used as ruminant feed, but fermented treatment is needed to increase their nutritional value. The study consisted of 2 phases of research. The first phase aims to find out the effect of oil palm midrib fermented by Phanerochaete chrysosporium on the physical and chemical qualities of feed, while the second phase to find out the effect on invitro digestibility. The design of the first stage used the factorial completely randomized design. On the second phase the design used the completely randomized design. The first phase showed significant effect (P <0.05) on the physical and chemical quality. The best of incubation time was 15 days and the best dose was 106 CFU/g. The second phase showed significant effect (P <0.05) on the digestibility of dry matter and organic matter. The best result of second phase is P3 treatment that used Phanerochaete chrysosporium + Saccharomyces cerevisiae in fermentation. It is concluded the use of Phanerochaete chrysosporium + Saccharomyces cerevisiae in fermentation can improve physical and chemical properties and increase the digestibility of oil palm midrib.
