| Abstract | Effects of modified cages with perch and cage density on behavior, egg production, and bone strength were investigated in hens reared either in conventional or modified cages with three densities, i.e. 2, 3, and 4 hens/cage. Neither cage typeeffect nor their interactions with cage densities were found. Hens in two hens/cage displayed higher percentage of feeding andpreening and lower percentage of standing and sham dust-bath with higher body weight change and femur strength than theircounterparts (p<0.05). Humerus strength of hens in two hens/cage was higher than of those in four hens/cage (p<0.05). Nodifferences were apparent between two vs. three hens/cage groups in humerus strength and between three vs. four hens/cagegroups in femur strength. An alternative to improve hen welfare in the conventional cages by perch provision is unlikely to beeffective as retaining the small group size with optimum area/hen would be more vital. |
