One day-old chicks transport: Assessment of thermal profile in a tropical region

Abstract: A B S T R A C TThe aim of this study was to assess the thermal profile of truck with different levels of box placement during one day-old chicks transport. An experiment was conducted through monitoring of 11 transport loads. A acclimatized truck was used in this research, with maximum capacity of 630 one day-old chicks boxes, totalizing 63,000 animals. The assessment of thermal environment was performed in 5 min intervals, through the following variables: temperature, relative humidity and specific enthalpy. … Show more

“…Thus, it was observed that only the average temperature and the maximum relative humidity values were within the recommended range of 32-35 °C and 50-60%, respectively (NAZARENO et al, 2015a;2015b). In addition to that, these variables had low standard deviations (1.993 and 5.722, respectively), demonstrating a ho mogeneous data distribution, as in SINGH & MATHUR (2005) …”

“…Some of the biggest issues of shipping alive chicks in air-conditioned trucks are related to thermal heterogeneity inside containers and inadequate air circulation (QUINN & BAKER, 1997;NAZARENO et al, 2015aNAZARENO et al, , 2015b, resulting in possible economic losses.…”

“…A preparação dos pintos após o nascimento e o transporte, tornou-se uma atividade da indústria avícola tão importante quanto a produção e criação das aves na granja (Nazareno et al, 2015a;2015b). De acordo com os níveis tecnológicos alcançados nos incubatórios e granjas de criação, como melhorias das máquinas e equipamentos, tornou-se inadmissível que a produtividade e a qualidade dos pintos sejam depreciadas, por exemplo, devido à sala de espera do incubatório com controle inadequado do ambiente.…”

“…A identificação de gargalos tecnológicos e em contrapartida a correção dos principais pontos críticos na etapa pré-porteira (nascimento, espera e alojamento), devem ser consideradas como essenciais para a produção de pintos de excelente qualidade (Nazareno et al, 2013;2015a). A idade das matrizes de corte influencia diretamente no tamanho e na qualidade dos pintos em razão da espessura da casca e do diâmetro dos poros do ovo, haja vista, que com seu envelhecimento se aumenta a capacidade da casca do ovo em permitir perda de água e trocas gasosas entre o embrião e o ambiente os quais têm, como consequência, pinto com massa corporal maior e/ou menor (Akyurek & Okur, 2009;Zakaria et al, 2009;Alsobayel et al, 2013).…”
