    Abstract: This work was carried out to investigate the effect of zinc picolinate on quality of eggs from Japanese quails. Ninety, 55-day-old Japanese quail (Coturnix coturnix Japonica) were randomly assigned to 3 treatment groups consisting of 6 replicates of 5 birds. Birds were fed either a control diet or a control diet (C group) supplemented with 30 (Z1 group) or 60 (Z2 group) mg Zn kg<SUP>-1</SUP> of diet. Eggs yielded from the birds were analyzed for quality. Supplementation with zinc picolinate to Japanese quail resulted in significant improvements of egg weight, eggshell weight, shell thickness and of egg yolk color and yolk indexes (p&lt;0.01). As a result, egg breakage is reduced due to increased strength of eggshell. Results showed that zinc supplementation improve the egg shell quality.
