“…In addition, at 14:00 h, temperature variation between the lowest (FB) and highest (CA) average was 0.59 °C, which was a small but significant difference (p<0.05). These results differ from those found by FIORELLI et al (2010), who observed the highest average values of air temperature and radiant heat load at different times in poultry prototypes with fiber-cement roofing but without using lining in the prototypes. Considering as an optimum range the values between 21 and 24 °C and a critical range the values between 15 and 35 °C (MACARI & FURLAN, 2001;NASCIMENTO et al, 2012NASCIMENTO et al, , 2013, the average dry-bulb temperature was outside the optimum range of thermal comfort ( Figure 4A).…”

This study aimed to assess different combinations of coverage materials in reduced models of animal husbandry facilities based on thermal comfort indices. It was conducted in an experimental area of the Research Center in Ambience located in São Paulo State, Brazil (22°42′30″ S and 47°38′00″ W). The performance of ceramic and fiber-cement (white painted) tiles was assessed associated with two types of polypropylene commercial linings (lining A and B) installed below the roof, and a thermo-reflective screen (lining C) installed above the fiber-cement roof. Microclimatic assessment of distorted reduced-scale models was performed at 15-minute intervals by registering the air temperature, black globe temperature, relative humidity and air velocity. Subsequently, black globe humidity index, specific enthalpy, and radiant heat load were calculated. The experimental design was randomized block design with 5 treatments and 15 blocks (replications), totaling 75 experimental units. The reduced-scale models with lining B presented a reduction for all thermal comfort indices. Lining C, installed on the coverage, showed no upgrading of environmental thermal conditions. Thus, lining B presented a better thermal performance regardless the tile type.

“…In this sense, FIORELLI et al (2010) andSILVA et al (2015) concluded that the use of long life packaging-based recycled tiles presented thermal comfort indices similar to those found with ceramic tiles and could be indicated as a coverage option for animal husbandry facilities.…”

Esta pesquisa foi desenvolvida com o objetivo de caracterizar os efeitos do ambiente térmico nos índices de conforto, respostas fisiológicas e no desempenho de bezerras Girolando, alojadas em abrigos individuais cobertos com diferentes materiais. O experimento foi realizado entre janeiro e março de 2012, com duração de 56 dias, conduzido com 24 bezerras de composição genética 7/8 Holandês-Gir aos 15 dias de vida e com peso médio de 40,6 kg. Os tratamentos consistiram em três tipos de cobertura, palha de palmeira, telha de polímero reciclado e telha de fibrocimento, com 8 repetições. O delineamento experimental adotado foi o inteiramente casualizado com comparação entre médias pelo teste de Tukey (p < 0,05). A entalpia e a carga térmica radiante diferiram estatisticamente em todos os tratamentos sendo os menores valores apresentados pelos abrigos com cobertura de telha reciclada, 59,3 kJ kg-1 de ar seco e 444,8 W m-2, respectivamente. Não houve diferença significativa em nenhuma das variáveis fisiológicas estudadas, porém a frequência respiratória esteve elevada em todos os tratamentos sendo mais acentuada nos animais sob cobertura de fibrocimento (57,2 mov min-1) indicando mais suscetibilidade ao estresse térmico.

“…According to FIORELLI et al (2010) the broiler industry in Brazil has shown strong growth regarding to productive and commercial factors, standing out in the international market since 1995 with higher rates of growth in production and worldwide export. This led Brazil in 2004to hold the position of world's largest exporter in that year.…”

“…Alternative ways of recycling or reuse of solid waste should be searched. For this purpose, new technologies are been developed, such as the use of different materials to cover the installations (FIORELLI et al, 2010), improvement of animal's food quality (EYNG et al, 2011;MINAFRA et al, 2010;NASCIMENTO et al, 2009) and the use of biogas for heating of poultry houses (SANTOS et al, 2007). ORRICO JUNIOR et al (2010c) investigated the technical feasibility of using anaerobic digestion to treat waste from poultry litter and carcasses of pre-composted poultry.…”

Chicken feet can be used as an alternative source of collagen for the development of new products. In this sense, the aim of this study was the production of a product similar to gelatin from collagen extracted from chicken feet and the evaluation of sensory quality. The products were produced in two distinct flavors, with grape flavor called GU and pineapple flavor called GA. Subsequently, we compared these formulations with gelatin of a trademark established in the market. We used in the verification of sensory acceptability of products a hedonic scale of 9 points and the availability of consuming the product by 30 untrained tasters. According to the results, all formulations showed good levels of acceptability, indicating the collagen from chicken feet as an alternative source of high quality in the production of gelatin.KEYWORDS: chicken feet; quality; sensory analysis, utilization of byproduct; new product development. PRODUÇÃO DE UM PRODUTO SIMILAR A GELATINA A PARTIR DE COLÁGENO DE FRANGORESUMO: Os pés de frango podem ser aproveitados como fonte alternativa de colágeno no desenvolvimento de novos produtos. Neste sentido, objetivou-se com o presente estudo a produção de um produto similar a gelatina a partir de colágeno extraído de pés de frango e a avaliação da qualidade sensorial. Os produtos foram elaborados com dois sabores distintos, sendo uva denominada GU e sabor abacaxi denominada GA. Posteriormente, compararam-se as formulações com uma gelatina de marca comercial consolidada no mercado. Utilizou-se, na verificação da aceitação sensorial, dos produtos escala hedônica de 9 pontos e a disponibilidade em se consumir o produto mediante 30 provadores não treinados. De acordo com os resultados, todas as formulações obtiveram bons níveis de aceitabilidade, indicando o colágeno dos pés de frango como fonte alternativa de elevada qualidade na produção de gelatinas.PALAVRAS-CHAVE: pés de frango; qualidade; análises sensoriais; aproveitamento de subproduto; desenvolvimento de novo produto.
