This study was aimed at determining the effect of storage duration and butyric acid supplementation on egg quality of laying hens in the third phase of production. It used experimental method that employed Completely Randomized Factorial Design consisting of 2 factors; Factor A and Factor B. Factor A had 4 treatment levels of supplementation of butyric acid in diets; A0 (control treatment), A1 (0.175 g/kg diets), A2 (0.350 g/kg diets), and A3 (0.525 g/kg diets), while Factor B consisted of 3 levels of storage duration including B1 (1 week), B2 (2 weeks), and B3 (3 weeks). Each factor had 4 replications and each replication or unit consisted of 10 laying hens. The observed variables included egg weight, albumen weight, and yolk weight. The results indicated that the supplementation of butyric acid has no significant effect on the decrease of egg weight, albumen weight and yolk weight. Duration of storage significantly affected to decrease egg weight, albumen weight, and yolk weight. It can be concluded that there was no significant interaction between administration of butyric acid and duration of storage to the egg quality but duration of storage was significantly influenced the egg quality of laying hens in the third phase of production.
