The present investigation: Influence of the time of egg storage, in reproductive hens of the Cobb-500 line, previous to the incubation, above the incubability parameters, was developed in the "Rodríguez" SAC Incubation Plant, with a duration of three months, whose objective was to determine the influence of egg storage time, prior to incubation, on hatchability parameters. For this study, 280 fertile eggs were used from batch 4B of breeding hens of the Cobb 500 line of the same hatchery. The Completely Random Design was used with four treatments and two repetitions. Each experimental unit was represented by a group of 70 eggs. The treatments were: T0 (Fresh eggs), T1 (1-3 days of storage), T2 (3-5 days of storage), T3 (5-7 days of storage). As for the results obtained, regarding moisture, the highest loss corresponds to treatment two, with 13.72%; the highest fertility was obtained in t...
