Abstract
Improving the quality of palm oil waste through fermentation with Phanerochaete chrysosporium (ligninolityc fungi) and Neurospora crassa (carotenogenic fungi) reduced its crude fiber content, especially lignin and cellulose and produced β carotene. Fermented palm oil waste (palm oil sludge and palm kernel cake, 1:1) products was increased their utilization in poultry rations. An experiment was conducted to determine the effect of feeding pal oil waste fermented by Phanerochaete chrysosporium and Neurospora crassa on laying performances and egg quality of laying quail. This experiment was arranged in a completely randomized design with fife dietary treatments: 0%, 5%, 10%,15% and 20% palm oil waste fermented in the diets and five replications. 200 laying quail Coturnix coturnix japonica (11 week of age) were randomly allocated into 5 treatments (10 birds per treatment) and 4 replications. Diets designed iso nitrogen 20% and iso metabolism energy 2800 kcal/kg. Results of the experiment indicated that feed intake, quail day production, egg weight, egg mass production, feed conversion were not affected (p>0.05) but egg cholesterol was affected (p<0.01) by increasing palm oil waste fermented products in the diet. Conclusion of the experiment that utilization 20% palm oil waste by using Phanerochaete chrysosporium and Neurospora crassa maintained laying performance of quail and reduced egg cholesterol 20.15%.
