Abstract

In the present study, we investigated the effects of dietary edamame isoflavones (eISF) and fish oil lemuru (Sardinella lemuru) (MIL) supplementation on Japanese quail (Coturnix coturnix japonica) egg production and physical egg quality. Birds (n = 140; 14 wk old) were randomly assigned to 1 of 5 groups consisting of 28 birds (4 replicates of 7) and were fed a basal diet or the basal diet supplemented with either 0.5% or 1% of eISF and 2% or 4% of MIL. The experimental period lasted 16 wk old with a 16L:8D lighting schedule. Dietary eISF supplementation and fish oil lemuru did not affect feed intake, egg production, egg weight, and shell thickness on the other hand they improved feed efficiency to a greater extent than the other levels (1% eISF and 4 % MIL). However, egg yolk color was increased (P < 0.0001) at the highest level eISF 1% and 4% supplementation. It can be concluded that the present study indicated that supplementing with dietary eISF and fish oil lemuru improved egg yolk color but did not affect egg production.
