| Na busca por respostas quanto às condições de bem-estar animal, visou-se a avaliar neste trabalho o comportamento de pintainhos nas duas primeiras semanas de vida, por meio de processamento de imagens digitais. O experimento foi realizado em dois galpões comerciais, utilizados para criação de 15.200 aves de corte por galpão, durante um ciclo produtivo, dotados com fornalha a lenha de aquecimento indireto do ar. Foram instaladas duas câmeras de vídeo por galpão para aquisição de imagens digitais. Uma das câmeras possuía inclinação angular de 45º, e a outra, inclinação angular de 90º em relação ao solo. As imagens foram analisadas para cada condição climática diária e binarizadas, sendo depois processadas por meio de descritor de agrupamento/dispersão e... |

| To maintain a competitive development of the Brazilian aviculture, some measures must be taken to enable the identification and reduction of risks to the health of birds, as well as for the physical environment. Therefore, the aim of this study was to evaluate the effectiveness of three different systems of minimum ventilation (positive pressure - SVMP, negative pressure - SVMN and natural ventilation - SVMNat) in the air quality during the first 21 days of life of broiler chicks, during winter. Three points were selected along the length to verify ammonia, carbon monoxide and oxygen concentrations at 3a.m., 9a.m., 3p.m. and 9p.m., by the respiration level of birds and workers. The averages of pollutant gases did not exceed the tolerance levels for the... |

| ABSTRACT The aim of this study was to monitor and evaluate the thermal environment and undertake a complete mapping of the variables air temperature, air relative humidity, and temperature-humidity index for broilers. The research was conducted during the winter, in Brazil, in a commercial poultry house fully walled with concrete-block masonry, equipped with a full-time negative-pressure mechanized ventilation system and indoor-environment air heating by a wood-burning furnace located outside the facility. The shed was fully automated and housed 30,000 birds at a density of 15 birds m-2. Thermal-environment data analysis revealed that the masonry-wall model did not ensure homogeneous thermal distribution within the poultry house, with the central region... |
