The aim of the present study was to evaluate the effect of a commercial product based on oregano extract (Origanum vulgare) on the productive response and egg quality in laying hens at second production phase, it lasted 56 days. 2000 “H&N Brown Nick” hens of 54 weeks of age were used, distributed in two groups: Control Group, basal diet with APC (zinc bacitracin, 50 ppm) and Experimental Group, basal diet without APC, supplemented with oregano extract (250g per Ton of feed). Weight gain (g), feed consumption (g), egg production (%), egg mass (g), feed conversion rate (Kg / Kg) and mortality were evaluated as productive response parameters; and egg weight, shell weight, shell pigmentation and yolk as parameters of egg quality. The data obtained were evaluated by means of the Student's T test and Kruskal Wallis, with a significance level of 95%. The results obtained did not show significant statistical inference for the productive parameters and shell quality. However, the eggs of the Experimental Group showed a lower percentage of broken eggs (p<0.05). It is concluded that the addition of the commercial product based on oregano extract at a rate of 250 g per ton of feed shows similar results to the use of zinc bacitracin (50 ppm) as APC, and also reduces the percentage of broken eggs.
