dc.description.abstract	The objective of this work was to evaluate the heat dissipated in broilers during the first two weeks of life and to estimate with infrared thermography the loss of sensible heat from birds. The environmental conditions were pre-established in wind tunnels using the automatic monitoring and control system, where only air temperature values were varied during each experimental week. Thus, the heat exchanges through convection and radiation of each animal were calculated by means of equations for the first and second week of life, and the temperature of the broilers was obtained by means of thermographic images. Has been found that the surface temperatures of the birds are correlated with air temperature and that they suffer greater heat dissipation when below their thermal comfort zone and as the bird develops.	pt_BR

dc.description.resumo	Objetivou-se com o presente trabalho avaliar o calor dissipado em frangos de corte, durante as duas primeiras semanas de vida, e estimar a perda de calor sensível das aves com auxílio da termografia infravermelho. As condições ambientais foram pré-estabelecidas em túneis de vento utilizando o sistema automático de monitoramento e controle, onde variou-se apenas a temperatura do ar durante cada semana experimental. Desta forma, foram calculadas por meio de equações, as trocas de calor por convecção e radiação de cada animal para a primeira e segunda semana de vida, sendo a temperatura superficial dos frangos obtida por meio de imagens termográficas. Verificou-se que as temperaturas superficiais das aves estão associadas à temperatura do ar sofrendo maior dissipação de calor quando abaixo da sua zona de conforto térmico e à medida que a ave se desenvolve.	pt_BR
