The purpose of the present research was to analyze comparatively the productive performances of the Lohmann Brown Classic hybrid hens, kept in batteries with cages and on the ground, on permanent bedding. During the exploitation period (85 weeks in cages, 93 weeks on the ground), was monitored: intensity of egg laying, the dynamics of the production of eggs, egg weight, feeds consumption and the evolution of the body weight of hens. The hens grown in cages achieved superior productivity performances, in comparison to the ground grown hens: average egg laying intensity 87.83% versus 79.61%; average number of eggs at the age of 16 months 417.79 versus 349.23; the average egg weight 68.45 g versus 64.57 g; average body weight of hens 1947.65 g versus 1932.85 g. The daily consumption of feeds per bird varied between 124-171 g in the case of caged hens and between 130-150 g for the ground grown hens.
