In vitro Fermentation Characteristics of Palm Oil Byproducts Which is Supplemented with Growth Factor Rumen Microbes
Abstract
The aim of this experiment was to study the use of palm oil by products [oil palm fronds (OPF), palm oil sludge (POS) and palm kernel cake (PKC)], that supplemented with Sapindus rarak and Sacharomyces cerevisiae on digestibility and fermentation in vitro. Oil Palm Fronds was previously treated with 3% urea. The treatments consist of 50% OPF+30% POS+20% PKC as a control diet (A), B = A+4% Sapindus rarak, C = A+0.5% Sacharomyces cerevisiae and D = A+4% Sapindus rarak+0.5% Sacharomyces cerevisiae. Digestibility of DM, OM, ADF, NDF, cellulose and rumen parameters (NH3 and VFA) of all treatments were significantly different (p<0.05). Product of fermentation and digestibility treatment A were significantly lower than treatments B, C and D. The result indicated that supplementation Sapindus rarak and Saccharomyces cerevisiae were able to improve fermentability and digestibility of palm oil by product.
