The feed supply in poultry houses can be done manually or automatically, to require effort is believed that manual supply could expose the attendant to physical overload. Thus, the objective of this study was to evaluate the ergonomic factors, and effect on posture and biomechanics of workers in poultry houses equipped with manual or automatic feeder. The analyzed factors were: physical work load, thermal environment, noise, lighting, postural analysis and biomechanics. It was found that in the sheds where the food supply system was manual, workers were exposed to greater physical effort. Based on the thermal environment management it was considered heavy for the two supply systems. The postures used in most activities deserve immediate corrective action. The handling in sheds equipped with manual feeder exposes workers to risk of injury in the shoulder, elbow, back, hip, knee and ankle. Thus, it can be concluded that management in poultry facilities equipped with manual feeder can be considered detrimental to the attendant exposing him to health risks and body damage.
