Última Noise analysis to evaluate chick thermal comfort Scientia Agricola Moura,Daniella Jorge de; Nääs,Irenilza de Alencar; Alves,Elaine Cangussu de Souza; Carvalho,Thayla Morandi Ridolfi de; Vale,Marcos Martinez do; Lima,Karla Andrea Oliveira de. The relationship between thermal environment and chick performance has widely been evaluated, however the consideration that the assessment of the comfort may be estimated by interpreting both amplitude and frequency of bird vocalization under tropical housing conditions is a new concept. This research had as objective of estimating thermal comfort for chicks during the heating phase using this new concept. An experiment was carried out inside a climate controlled chamber (A) for establishing the behavioral pattern related to environmental temperature limits. Forty five chicks were reared inside a 2.3 m² box. A video camera was placed 2.0 m above the birds and the images were captured and registered in a computer. From the pattern determined in the...
