Kecernaan Jerami Padi yang Disuplementasi Zn Lysinate dengan Teknik In Vitro

Abstract

This study was conducted to determine the digestibility of rice straw that supplemented by Zn Lysinate with in vitro techniques. This research was held in Laboratory of Animal Feed and Nutrition, Departement of Animal Science, Faculty of Agriculture, Sriwijaya University. Completely Randomized Design (CRD) with four treatment and four replications, were used : P0 (rice straw control), P1 (rice straw with Zn Lysinate 0,1%), P2 (rice straw with Zn Lysinate 0,2%), P3 (rice straw with Zn Lysinate 0,3%). Observed parameters were dry matter digestibility (DMD), organic matter digestibity (OMD), and N-ammonia concentration. The result showed that the highest dry matter digestibility was on P3 (33.86%), whereas the highest organic matter digestibility and N-amonia were on P2 treatment ; 44.94% and 1.50 mM, respectively. Supplementation of Zn Lysinate for rice straw had effect on Dry Matter Digestibility (DMD), but had no effect on Organic Matter Digestibity (OMD) and N-Amonia concentration.
