| The objective this study was to assess ergonomic factors, posture and biomechanics of workers of a broiler egg hatchery. The analysis of ergonomic factors was based on physical work load, thermal environment, and exposure to light and noise. The posture of workers was analyzed using photographic records which were evaluated by the software program OWAS (Ovako Working Posture Analysing System). A biomechanics analysis was also performed based on the photographs taken of the employee at various angles, which were used as inputs to the Michigan two-dimensional biomechanical model software program. The results show that certain activities can be considered unhealthy due to the exposure of employees to physical and thermal overload. The continuous noise levels... |

| The objective of this study was to determine thermal comfort ranges, as evaluated by air temperature and black-glove temperature and humidity index (BGTHI), for starter meat-type quails. Nine hundred quails were randomly distributed into five environmental chambers. Each chamber was programmed to provide different temperatures weekly. The following thermal environments were provided: SC - severe cold, MC - moderate cold, TC - recommended comfort environment, MH - moderate heat, and SH - severe heat. The best live performance was obtained when quails were submitted to temperatures of 36-39 ºC and BGTHI of 87.1 ± 0.4 and 91.4 ± 0.6 during the first week of rearing. Temperatures of 27-30 ºC and BGTHI of 75.8 ± 0.4 and 79.9 ± 0.6, during the second week, and... |
