Broiler Response to the Utilization of Fermented Palm Oil Sludge with Phanerochaete chrysosporium and Neurospora crassa

Palm Oil Sludge (POS) had the potential as an ingredient of broiler ration. POS requires to be processed by fermentation of P. chrysosporium and N. crassa to increase nutritional value. The aim of this research was to evaluate the utilization of Fermented Palm Oil Sludge (FPOS) with P. chrysosporium and N. crassa in rations of broiler. One hundred and sixty mixed-sex a-day-old chicks (DOC) Cobb CP 707 breed of broiler procured from Charoen Pokphand Indonesia were used in this experiment. Broiler were placed in 20 wire cages; each unit consists of 8 birds. Feeding treatment was carried out for 35 days. Ration was composed of 22% iso-protein and 3000 kcal/kg of iso-metabolic energy. The design of this experiment is a completely randomized design with five treatments and four replications. Treatments were: T1) 0% FPOS (control diet), T2) 15% FPOS, T3) 20% FPOS, T4) 25% FPOS and T5) 30% FPOS in broiler ration. Feed intake, body weight gain, feed conversion ratio, body weight, carcass percentage, and abdominal fat percentage) were found to be significantly (P<0.05) decreased with any treatment except carcass weight (P>0.05) as compared to control group. In conclusion, FPOS with combination of P. chrysosporium and N. crassa was capable to be used up to 25% in rations of broiler.
