Comportamento de frangos de corte submetidos a diferentes ambientes térmicos

Abstract: RESUMO: É um desafio manter o ambiente térmico, e como as aves alteram seu comportamento em resposta a este ambiente, entender o comportamento dos animais ajuda nes te controle. Neste contexto, objetivou-se, com o presente trabalho, avaliar o comportamento de frangos de corte, durante as duas primeiras semanas de vida, submetidos a diversas variações de temperatura do ar em câmaras climáticas. Os animais foram filmados por câmeras de vídeo, possibilitando o monitoramento das aves no estudo dos comportamentos c… Show more

“…In an evaluation of the behavior of broilers in the initial life stage through images, Schiassi et al (2015) found that under thermal stress conditions caused by the cold -a situation occurring in facilities with insufficient heating and flaws, similarly to the present study -birds tend to remain most part of the time clustered in groups, which compromises their development and productive efficiency. Cândido et al (2016) observed that broilers reared under the temperatures of 27, 24, and 21 o C in the first, second, and third week, respectively, which are lower than those recommended in the literature, showed higher weight gains and feed conversion in comparison with the other imposed temperatures of comfort and cold stress.…”

“…No caso de frangos com uma semana verifica-se uma temperatura muito abaixo da pretendida. Os pintos devido à condição de stress por frio, procuraram manter-se agrupados, com a tendência de diminuir a frequência de idas ao comedouro e bebedouro em relação aos animais criados em ambientes a 33°C [38,39]. Com temperatura do ar estimada próxima de 22,6 º C, no caso dos frangos de 4 semanas, apresentam-se dentro da faixa de conforto [30,40,41,42].…”

“…For the poultry industry to reach levels of excellence it has sought to improve productivity, without, however, increasing production costs (Ponciano et al, 2011). It is known that when the thermal conditions are inadequate, this can affect their well-being and negatively impacting production performance (Schiassi et al, 2015).…”
