“…The coefficient of correlation for the body parts with feathers was 0.6, and the probable reason of the small correlation is the air layer that increases the thermal inertia between the skin and the feathers. Malheiros et al (2000) reported an increase in skin thermal conductance when the air temperature rose from 20 to 40°C, implying in an increase in peripheral blood flow, which might be the determinant factor to change the surface temperature during exposure to different environmental temperatures. Cangar et al (2008) found that the comb had the highest temperature gradient while the wing had the lowest.…”

“…Ward et al (1999) and Cangar et al (2008) suggested the overall emissivity value of 0.95 for the bird. Malheiros et al (2000) used ε = 0.94 to determine the variation of the surface temperature in post hatch pullets. The images of the broiler surface were divided in 14 regions to allow assessment of regional Ts distribution, as suggested by Ward et al (1999).…”

“…A média geral de TC encontrada nesta pesquisa foi de 38,9 °C, com a qual corroboram Malheiros et al (2000), os quais encontraram mesma média de TC de 38,9 °C para situação de estresse térmico por frio em câmara climática em que os pintos foram submetidos à temperatura ambiente de 20 °C no primeiro dia de vida.…”

“…Com base na temperatura superficial média geral (28,2 °C) foi possível detectar a condição de estresse por frio nos pintos de um dia, que estava abaixo da TSM de 31,2 °C obtida por Malheiros et al (2000) em ambiente frio de 20 °C.…”

“…Em condições de frio foram observados quadros de ascite e redução de peso corporal aos sete dias (Malheiros et al, 2000;Mujahid e Furuse, 2009). Sob elevadas temperaturas pode ocorrer desidratação, aumento da temperatura cloacal e frequência respiratória, bem como variações no peso corporal na primeira semana (Dionello et al, 2002).…”
