Pengaruh Silase Daun Salak dalam Pakan Komplit terhadap Kecernaan dan Karakteristik Fermentasi In-Vitro

Abstract

This study aims to determine the best percentage in the utilization of salak leaf silage in complete feed on dry matter digestibility, organic matter digestibility, pH value, VFA concentration, NH3 concentration and microbial protein synthesis. The method used in this study was an experimental method (Tilley and Terry, 1963) with a 4 x 4 Randomized Block Design (RBD), with 4 different treatment rations and 4 times rumen fluid collection as a repeat group. The percentage of salak leaf treatments in complete feed were: P0 (15% elephant grass in complete feed), P1 (15% salak leaves in complete feed), P2 (30% salak leaves in complete feed), and P3 (45% salak leaves in complete feed). complete feed). The observed variables consisted of dry matter digestibility, organic matter digestibility, pH value, VFA concentration, NH3 concentration and microbial protein synthesis. The mathematical model used is analysis of variance and if there are differences between treatments it is continued with the DMRT (Duncan's Multiple Range Test) test (Steel and Torrie, 1991). The results showed that the treatment ration had no significant effect (P>0.05) on rumen fluid pH value and had a very significant effect (P<0.01) on dry matter digestibility, organic matter digestibility, pH value, VFA concentration, NH3 concentration and microbial protein synthesis. The conclusion of this study was that using 30% silage of salak leaves in complete feed could maintain the pH value and increase the digestibility of dry matter digestibility, organic matter digestibility, pH value, VFA concentration, NH3 concentration and microbial protein synthesis
