- Impact of Exposure to Cold on Layer Production FMS Alves GA Felix ICL Almeida Paz IA Nääs GM Souza FR Caldara RG Garcia Agrociencias heat exchange Infrared image egg production housing environment economic evaluation Infrared thermographic images were used to evaluate the effect of the exposure of layers to cold. In this trial, 540 Isa Brown® layers with an average age of 69 weeks were housed in a conventional layer house typically used in Brazil during a period of cold environmental temperatures. Environmental and heat-transference data were recorded between July 13-16, 2010. It was verified that layers under cold stress conditions lost four times more energy that the recommendations trying to maintain their body temperature. Due to their reduced feed intake capacity, hens are not capable of increasing the availability of the metabolic energy required to maintain their body temperature and egg production, consequently resulting in economic losses. 2012 artículo científico 1516-635X https://www.redalyc.org/articulo.oa?id=179724984010 en http://www.redalyc.org/revista.oa?id=1797 Revista Brasileira de Ciência Avícola application/pdf Fundação APINCO de Ciência e Tecnologia Avícolas Revista Brasileira de Ciência Avícola (Brasil) Num.3 Vol.14
