Abstract

Muhammad 'Wahyudi Barus, 2004. "Utilization of palm oil sludge fennented by Aspergi/lus niger in poultry diet on the perfonnance of DOC to 6 weeks old broiler." Under advices of Jr. Iskandar Sembiring, MM as chief advisor and Ir. Eniza Saleh, MS as a second advisor." The experiment conducted at Biological Veterinery Laboratory at the Animal Husbundary divition of Agricultural Faculty at University of North Sumatera on Dr. A. Sofyan street no 3rd Medan. The experiment targeted to observe response of palm oil sludge fennented by Aspergil/us niger in poultry diet on the performance of broiler. Palm oil sludge a by product of palm oil industry is not commonly used in poultry feed due to some limmiting factors such as low protein and amino acids and high crude fiber content. These limmiting factors were expected to be reduced by fermentation technology. The experiment was conducted using completely randomized experimental design that alocated into 20 cages with birds in each cage. Each 5 group of birds were fed with one of 5 experimental diets. The diets were M0 (control diet), M1 (5% palm oil sludge fermentattion in the diets), M2 (10% palm oil sludge fermentattion in the diets), M3 ( 15% palm oil sludge fermentattion in the diets), M4 (20% palm oil sludge fermentattion in the diets). The experimental die1ts were fed for 6 weeks and the performance were observed also masured at the end of the trial. The results showed the higest average consumtion at M0 (646,08 g), then M1 (602,11 g), M2 (579,34 g), M3 (573,85 g), and the lowest average consumtion at M4 (549,69 g). The highest average weight gain at M0 (326,73 g), M1 (306,91 g), M2 (303,16 g), M3 (293,56 g) and the lowest average weight gain at M4 (289,00 g). The best average feed convertion at M2 and M4 (1,84), then M1 (1,88), M0 (1,95), and the worst average feed convertion at M3 (2,08).

The results of the experiment showed that palm oils sludge fermentation at the level 0% - 20% in the poultry diet depressed consumtion and broiler body weight at (P<0,05) although did not affect convertion at (P>0,05).
