Zootecnia de precisão: análise de imagens no estudo do comportamento de frangos de corte em estresse térmico

Abstract: A preocupação em se atingir níveis de bem-estar para que a produção avícola seja maximizada vem, ao longo desses últimos anos, ganhando maior importância pela complexidade com que os fatores de produção estão correlacionados. Há um número grande de variáveis influenciando o microclima dentro de uma instalação, e conhecer sua interferência na produtividade final é determinante para uma compreensão melhor dos fenômenos ambientais. A manutenção do conforto térmico dentro dos aviários é um dos problemas enfrentado… Show more

“…The threedimensional representation of half the fruit shows a smooth surface, without noise and without problems of discontinuity on the edges, as questioned by Braga et al (2009), evidencing that the use of only one camera associated with digital correction can overcome the problems caused by the perspective. The correction or "unwarping" is a necessary step for the improvement of images, according to Gholipour et al (2011) and Sevegnani et al (2005). The deformations in the digitalized images of macaw palm fruits generated by the perspective, due to the use of only one camera, were corrected by using the technique of correction of image deformations.…”

“…The technique of correction of image distortions, known as unwarping, has been applied to improve images from magnetic resonance (Gholipour et al, 2011) in applications such as images of behavior of broilers (Sevegnani et al, 2005). The potential of application of unwarping in agriculture is great, since the inference on information related to crops can be performed through optical biometry.…”

“…Tais variáveis ambientais segundo Marchini et al (2007) e Sevegnani et al (2005) são desfavoráveis à criação de frangos de corte nessas regiões, pois estes são muito suscetíveis à elevação de temperatura ambiente. Seu desempenho zootécnico é prejudicado, resultando num crescimento abaixo do esperado e peso à idade de abate inferior ao comparado a animais criados em zonas com maior conforto térmico.…”

“…Monitoring video images has been used in research for studying animal's behaviour, welfare and ethogram's development due to its efficiency and accuracy, since the animal's behaviour is not influenced by human presence, in addition to this it allows researchers to establish concrete observations and certainty of animals behaviour (Sevegnani et al 2005;Silva et al 2006;Barbosa Filho et al, 2007).…”
