The Digestibility of Different Level of Palm Kernel Cake and Rice Bran Supplementation in Sheep

The purpose of this study was to evaluate the effect of giving oil Palm Kernel Cake (PKC) and rice bran with different proportions to the digestibility of dry matter (DM), organic matter (OM), crude protein (CP), crude fiber (CF), and energy in sheep. Twelve (12) sheep were divided into 3 treatments with 4 animals each, namely T1: supplementation of 15% PKC + 40% rice bran, T2: supplementation of 20% PKC + 35% rice bran, and T3: supplementation of 25% PKC + 30 % rice bran. All livestock received supplementation of 2% body weight and were given ad libitum fresh grass and drinking water. This research was conducted for 21 days, consisting of 14 days adaptation period and 7 days collection period. Samples feed offered, feed residue, and fecal output were daily collected, dried in the sun to reduce water content, stored, and measured by DM, OM, CP, energy, CF, and energy. The data obtained were then analyzed using ANOVA, and continued with Duncan's Multiple Range Test to see the difference among the means. The results showed that increasing percentage of PKC in feed supplementation did not significantly increase (P> 0.05) the digestibility of DM, OM, CP, and CF in all treatments, while the energy digestibility was increased especially at P3 which was significantly higher (p<0.05) compared to P1. The increasing percentage of PKC in feed supplementation has reduced the DM intake.
