The aims of present study was to determine the effect of dietary supplementation of palm oil waste fermented with Phanerochaete chrysosporium and Neurospora crassa (POWF) with ratio 1:1 on performance and some egg characterizes of laying Japanese quails. This experiment used 200 quails (Coturnix-coturnix japonica) aged 20 weeks, with 70% egg production. This study used an experimental method with a completely randomized design (CRD) with four treatments (0%, 8%, 16%, and 24% POWF and five

... ations). The results of this research showed that the use of POWF in the diet was not affected to feed consumption, daily egg production, egg mass, egg weight, and feed conversion. But, a significant difference in blood total cholesterol, LDL, HDL, egg cholesterol, and index egg yolk color was obsereved, and no significant effect on triglycerides and egg yolk fat. In conclusion, feeding the mixture of palm oil waste fermented with Phanerochaete chrysosporium, and Neurospora crassa with ratio1:1 can be used up to 24% in laying quail rations, without any adverse effect on egg production. It may decrease the blood cholesterol and egg yolk cholesterol.
