Abstract
Palm oil sludge is a by-product of palm oil processing which contains nutritional value for use as a poultry feed supplement. This study aims to determine the effect of the use of palm oil sludge fermented with Pleurotus ostreatus (POSF) on cholesterol and fat content, and egg yolk index of quails feed this supplement . Two hundred 20 week old quails (Coturnix coturnix japonica) were used in this study which used completely randomized design (RAL) with 5 treatments and 4 replications. Treatment was the FPS content of the feed which varied from 0% FPS for treatment A, 6% for B, 12% for C, 18% for D, and 24% for treatment E. The parameters measured were egg yolk cholesterol (mg / 100g), egg yolk lipid content(%) and yolk index. The results of the analysis of variance showed that the use of fermented palm sludge with Pleurotus ostreatus had a highly significant effect (P <0.01) on egg yolk cholesterol but no significant effect (P> 0.05) on egg yolk fat content or yolk index . Quails fed higher levels of POSF (D,E) produced eggs with highly significantly lower (P <0.01) cholesterol levels than the control. The results of the study suggest quail feed could be supplemented with 24% POSF to effectively reduce egg yolk cholesterol up to 21% but such supplementation is unlikely to have an effect on yolk fat content or yolk index.
