In order to assess the effect of dietary supplementation of conjugated linoleic acid (CLA) on fatty acid composition and egg quality, a study was carried out on three groups of laying hens, each of 9 subjects, fed diets supplemented with 0, 1.25 and 2.5% CLA. Increasing CLA concentration in diet, yolk CLA concentration increased from 0.15 (Control) to 6.04 and 11.73 mg/kg (CLA 1.25 and CLA 2.50, respectively). The most representative isomer was cis-9, trans-11. The saturated fatty and monounsaturated fatty acid in yolk increased and decreased, respectively, with CLA supplementation. Egg yield and quality traits did not show any significant difference among groups.

Abstract
In order to assess the effect of dietary supplementation of conjugated linoleic acid (CLA) on fatty acid composition and egg quality, a study was carried out on three groups of laying hens, each of 9 subjects, fed diets supplemented with 0, 1.25 and 2.5% CLA. Increasing CLA concentration in diet, yolk CLA concentration increased from 0.15 (Control) to 6.04 and 11.73 mg/kg (CLA 1.25 and CLA 2.50, respectively). The most representative isomer was cis-9, trans-11. The saturated fatty and monounsaturated fatty acid in yolk increased and decreased, respectively, with CLA supplementation. Egg yield and quality traits did not show any significant difference among groups.
