Activities and Ergonomics of Workers in Broiler Hatcheries

Abstract

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 and lighting were outside the range considered adequate by the regulations of the Brazilian Ministry of Labor. The manner in which certain activities are carried out when associated with weight and poor posture can result in body lesions in broiler hatchery employees. It is therefore necessary to apply specific ergonomic programs, including scheduled breaks, training, and other measures in order to reduce or to eliminate the risks involved in these activities.

“…In poultry, Scott and Lambe 120 ) recorded videos of tasks carried out by workers collecting the eggs of penned chickens and concluded that the postures adopted to collect the eggs were not the most suitable, proposing corrective measures. Finally, on a chicken farm, Carvalho et al 36 ) used the OWAS and the Michigan test 27 ) with the help of computer evaluation tools to warn of strained postures with possible MSD consequences.…”

“…There are different computer programs which have able to apply this method, allowing saving time of work, and which have been already used in several studies 34 , 35 , 36 , 37 ) .…”

Improving the management of poultry production: Mobile application development and validation

“…Poultry farmers might obtain information to provide favorable conditions that contribute to making decisions in the production process in real-time to maximize the productivity of the animals, allowing the expression of their genetic potential. Similarly, an appropriate working environment is desirable to preserve the health of workers and ensure maximum performance and quality of activities (Alencar et al, 2009;Carvalho et al, 2015). Animal welfare is another consumer demand that has been imposed by importer's market and worldwide adopted to minimize health issues and avoid hunger, thirst, or the lack of natural expression (Bessei, 2006;Federici et al, 2016).…”
