Effect of Mineral Mix Supplementation in Silage of Palm Frond Grated (PFG) and Palm Sludge on Digestibility and Delay Quality By In Vitro Methods

By-products from oil palm can feed ruminants such as fronds (OPF) and sludge (PS). Judging its continuous, cheap, abundant availability the industry, well a source of fiber or component in complete for ruminants, it is potential that be used animal feed. However, use livestock production minimal due to their complex structure, high lignin content, low protein content. So, needs management technology on OPF. The design was Completely Randomized Design (CRD) with three treatments five repetitions: P0 Palm frond silage (30%) + (70%) P1 Silage Mineral Mix 1% P2Palm 2%. data obtained were analyzed variance according used, if there differences between treatments, continued analysis using Duncan Multi Range Test Based results statistical showed treatment powder supplemented mineral mix vitro decreased digestibility value dry matter (P<0.05). different shown organic matter, where increased occurred supplementation mixes. no significant difference (P>0.05) VFA NH3 values. study's results, concluded significantly decreases but increases matter. Nevertheless, given did not have effect quality fermentation, which included NH3.
