Última COMPUTATIONAL FLUID DYNAMICS (CFD) APPLICATION FOR VENTILATION STUDIES IN BROILER HOUSES REA Curi,Thayla M. R. de C.; Moura,Daniella J. de; Massari,Juliana M.; Mesquita,Márcio; Pereira,Danilo F.. ABSTRACT With the recent increase in the number of acclimatized broiler houses in Brazil, design and adaptation of facilities to withstand the tropical weather conditions enabling the maintenance of ideal conditions without increasing costs have been major challenges. The aim of this study was to evaluate the ventilation system in solid-wall broiler houses using computational fluid dynamics (CFD). The research was carried out in the city of Amparo - SP (Brazil). The facility consisted of a broiler house enclosed by masonry sidewalls with tunnel ventilation equipped with exhaust fans (air outlet) and cooling pads (air inlet). The following variables were collected: wind speed and dry bulb temperature over 27 equidistant points inside the house at bird...

A common method for environmental control in livestock facilities is to use thermal insulation for exterior walls and roof. In regions with cool winters increasing the insulation thickness decreases the heating requirements, however in regions with hot summers may lead to unwanted increase of inside temperature, thus intensifying cooling loads. It is worth noting that financial thickness optimization of a broiler house external walls and gable roofs insulation for different orientations has not been sufficiently addressed, thus a detailed transient simulation was used to model existing energy audited broiler house and to calculate its annual heating and cooling loads. For that, hourly climatic data and all the heat and moisture gains and losses resulting...

Ano: 2021 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/6891 Relationship between ecological concepts and biosafety in broiler breeder farms Rev. Bras. Ciênc. Avic. Santos,CA; Falconi,FA. The entrance of poultry products into the trade world requires changes in the configuration of these products, such as programs that ensure their quality and biosafety for the consumers. This article aims at presenting new perception on poultry biosafety programs in broiler breeder farms from an ecological perspective, making these programs more efficient and cost-effective, i.e., more competitive. Using literature review, some convergences were found between ecology concepts and biosafety programs. One of these convergences is understanding the farm as an open ecosystem, integrating through adaptation the natural environment with the exotic environment. This also allows understanding how the production area interacts with the environment as to energy...

Ano: 2007 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1516-635X2007000300002 The Antifungal Properties of Peppermint and Thyme Essential Oils Misted in Broiler Houses Rev. Bras. Ciênc. Avic. Witkowska,D; Sowińska,J; Żebrowska,JP; Mituniewicz,E. ABSTRACT This study aimed at evaluating if essential oils misted in broiler houses reduce environmental fungi counts. The investigation was conducted in three experimental rooms, where broiler chickens were reared between 1 to 42 d of age. Every three days, the rooms were fogged with pure water (control) or with aqueous solutions of peppermint or thyme oils. On the next day, fogging samples from the air, flat surfaces, and litter were collected and quantitatively and qualitatively analysed for fungal contamination. The treatment with essential oils showed promising results. In the room fogged with thyme oil, aerial fungi growth was not as evident as in the control room, and presented the lowest average fungi count. Thyme oil was also the most effective in...
