“…Aparecida do Taboado is classified as in a dangerous situation (≥ 72.7 kJ kg -1 dry air). Rovaris et al (2014) suggest using comfort indexes with parameters to activate and control thermal cooling systems and mitigate external environment effects overproduction to obtain a more effective environment control.…”

Owing to the exponential growth of the human population and problems related to food supply, research focused on finding the most suitable approach to manage and geographically explore the environment using sustainable technologies stand out. The present study aims to produce a consistent interpolation of historical series of enthalpy (H) resulting in a thematic map of enthalpy, using the spline method as a kriging option in areas with few sampling points. The thematic map considers thermal comfort conditions to produce broiler chickens, that could be used as a management tool to reduce power consumption due to the cooling process of the facilities. It was verified that spline is an efficient method to create a suitable thematic maps representations of areas presenting a few sampled units. The geographical representation of enthalpy allowed the evaluation of the environments, concluding that the state of Mato Grosso do Sul, Brazil is inadequate for broiler chickens production without suitable thermal cooling systems. Evidence suggests introduction of aviculture in areas still unexplored, e.g., Chapadão do Sul and Sete Quedas.

“…Os autores atribuíram que o galpão Dark House possui maior controle das variáveis climáticas por apresentar maior isolamento térmico. Rovaris et al (2014) analisaram os sistemas de criação convencional e Dark House para as variáveis das aves: peso corporal aos 42 dias de idade, ganho de peso, consumo de ração, conversão alimentar, calo de pata, sendo os dados significativos, demostrando que as aves que foram criadas nos galpões Dark House apresentaram resultados mais positivos para as variáveis: peso corporal, ganho de peso e conversão alimentar. Estes resultados mostraram que o sistema Dark Douse proporcionou aos frangos um ambiente com melhor conforto e consequentemente maiores índices zootécnicos.…”

A avicultura de corte brasileira tem apresentado crescimento nos últimos anos, devido aos investimentos em inovações tecnológicas, o conhecimento interorganizacional e os estudos sobre o bem-estar animal, buscando assim novos sistemas e metodologias de trabalho, visando maior eficiência na produção de aves. O objetivo deste trabalho foi demonstrar as estruturas e o desempenho do sistema de criação chamando “Dark House” de aves de cortes, embora seja um sistema que apresente custos mais elevados para a produção, o produtor está considerando e aceitando a sua implantação para a criação. As diferenças entre os sistemas de criação estão sendo estudadas, entretanto, trabalhos prévios concluem que as aves desenvolvidas no sistema Dark House apresentam maiores desempenhos para peso final, ganho mais rápido de peso com consumo e conversão alimentar mais significativos, pois essa tecnologia foi desenvolvida pensando no bem-estar das aves; os viveiros são totalmente climatizados levando conforto animal e consequentemente aumento da produção.

“…Ligado a isso, fatores que irão influenciar na produção de ovos são o tipo do sistema de criação adotado, alimentação das aves e a qualidade das matérias primas, idade, condições do ambiente, manejo aplicado e protocolo sanitários (Netto et al, 2018;Oliveira et al, 2019;Rovaris et al, 2014). Outros parâmetros de relevância que precisam ser avaliados, a fim de se conseguir aumentar a validade dos ovos são tempo de armazenamento e temperatura de estocagem (Moura et al, 2008) (Lana, 2000).…”

The aim of the present study was to perform physical analyzes on eggs from hens with a cross between the Naked Neck and Giant Indian strains. Forty samples were collected from a rural property located in the municipality of Luziânia in the state of Goiás. These were separated into four groups (A, B, C and D) constituting 10 eggs per stall, from 05/12/2021 to 05/28/2021. The experimental design consisted of a factorial scheme with 4 (cards) x 10 (eggs) x 7 (days) x 11 (tests) x 4 (groups) x 40 (total sample). The physical analyzes were weighing and then classification according to the legislation applied to commercial eggs. The degree and classification of dirtiness, shell and percentage of this, presence of cracks, air chamber test, egg freshness, appearance of the albumen and yolk and its color were also evaluated. In the analyses, a weight of around 30 grams was found in one egg, 40 grams in thirty-seven eggs and 50 grams in two, with the maximum found being 52.51 grams and the minimum 39.04 grams. In the classification, 19 small type, 19 industrial and 2 medium type were found. Dirt in 4 absent, 6 discreet, 4 moderate, 4 intense and its classification 10% blood, 60% feces and 10% feathers. Bark coloring, 40% red, 40% white and 20% blue. Varied yolk tones as well, swollen, centralized and transparent albumen also consistent. In the shell percentage test consisting of evaluating the proportion between the weight of the shell washed and dried at room temperature for three days and the total weight of the egg, multiplying the result by 100% and the values found in the analyzes carried out were a minimum of 8% and maximum 13%, without significant changes due to the short storage time. It was concluded that seven-day-old eggs showed favorable physical characteristics in most of the tests performed. The theme presented is relevant, since this product is constantly present at the table of several families of rural producers, and it is essential to guarantee its quality.
