In vitro Fermentation Characteristics of Palm Oil Byproducts Which is Supplemented with Growth Factor Rumen Microbes

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
