The Effect of Concentrate Supplementation Made From Palm Oil Sludge and Several Local Feed Resources to Production Performance of Bali Calves

Abstract

This experiment was aimed to investigate the production performance of Bali calves male supplemented by concentrate diet made from palm oil sludge (solid decanter) and several local feed resources (rice bran, cassava flour, cassava leaf flour, and blood meal). This experiment was arranged in Latin Square Design with 4 treatments and 4 replications. Four weaned Bali calves ± 9 months old were used. The treatment was the ratio of concentrate and forage ration in the diet consisted of P1=80% concentrate (C) : 20% Forage (F), P2= 60%C:40%F, P3 = 40%C: 60%F, P4= 20%C: 80%F. Data were analyzed by using analysis of variance (ANOVA) and any significant differences were further tested with Duncan Multiple Range Test. The result showed that the treatment had no a significant effect on average daily gain, crude protein consumption and feed conversion value, but significantly decreased dry matter consumption. The results indicated that concentrate diet made from palm oil sludge and local feed resources had positive effect on Bali calves performance ranged about 0.167kg/day-0.271kg/day respectively.
