This study aimed to evaluate the behavior and the welfare of hens comparing a conventional housing system (laying cages in battery) with another system using litter + nest. The effects of environmental conditions (stress or comfort) on behavior responses of laying hens were also analyzed by precision techniques. Two groups of 10 birds of Hy-line W36 and Hy-line Brown stains, at the beginning of the production phase, were submitted to two environmental conditions (26°C with 60% RU or 35°C with […]
