Resumo: Avian influenza viruses (H5N1 and H7N2) triggered a great number of studies on biosafety, and one of the discussed solutions is the use of screen to enclose completely the poultry house perimeter, since it can avoid the contact of laying hens with other birds. Thus, the present study aimed to evaluate and compare the use of screen enclosing a conventional laying house perimeter by assessing acoustic and aerial environment inside the facility. The research was performed in a commercial egg production farm located in Southern Minas Gerais State, Brazil. It was carried out in an open facility, in which half area was enclosed by screen and the other half was maintained completely open. Hyline W-36 laying hens were housed. Sound intensity, ammonia concentration (NH3) and carbon dioxide concentration (CO2) were analyzed as variables. These variables were collected from six measuring points in each region (with and without screen), two in each alley (north, central and south). The results indicated that the use of screen did not alter the noise level, NH3 and CO2 concentrations inside the analyzed poultry house. However, the levels measured were smaller than to the thresholds that can offer health risks to birds and workers. Therefore, it may be concluded that the use of screen did not influence negatively the facility aerial environment.
