“…These results are consistent with those obtained by Jácome et al (2012 ) and Huber-Eicher et al (2013), who did not find any differences in the performance of Japanese quails and laying chickens, respectively, exposed to different LED light colors. On the other hand, Borille et al (2013) observed that laying chickens presented better egg production when exposed to red LED, white LED, and incandescent light sources.…”

“…Er et al (2007) found that the eggs of laying chickens exposed to red LED lamps were lighter than those reared under the incandescent lamp. On the other hand, Jácome et al (2012) and Borille et al (2013) did not find any egg weight differences among Japanese quails exposed to different light sources and colors.…”

Time of exposure and light intensity rearing house may affect the performance and egg quality of laying quails. This research aimed at evaluating the live performance, egg quality, biometry of the reproductive system, and the gastrointestinal tract of Japanese quails (Coturnix coturnix japonica) exposed to artificial light-emitting diodes (LED) of different colors in comparison with fluorescent lamps. A total of 240 Japanese quails were distributed in completely randomized experimental design with four treatments (fluorescent lamp, and green, red, or blue LED lamps) with six replicates of 10 birds each. Average egg weight and eggshell thickness were different (p<0.05) when LED bulbs were compared with fluorescent lamps. The egg weight of the birds exposed to the red LED was similar to those under a fluorescent lamp (p>0.05). The oviduct of 64-d-old hens exposed to green LED lighting was shorter (p<0.05) than those exposed to the fluorescent lamp. Red LED can be used to replace the fluorescent lamps, as they promote the same live performance, egg quality, and morphological development of the reproductive tract of laying Japanese quails.

“…The animal-environment interaction must be considered in the search for higher yields, and the different animal responses to the peculiarities of each region are determinant for a successful poultry farming system. Jácome et al (2012), studying quail production performance, observed mean THI of 70.03, justifying a prevalence of the thermal comfort zone in the studied environment.…”

A B S T R A C TThe objective of this study was to determine the effects of environment and electrolyte balance on environmental, physiological and productive indices of Japanese quails. For the experiment, 288 quails were distributed in a randomized block design with six treatments and six replicates of eight birds per experimental unit. The treatments consisted of one basal feed with 20.0% of crude protein (CP) and the others with a reduction of 3.0% CP to achieve six electrolyte balance levels (166.54; 153.47; 139.63; 139.63; 117.13 and 166.49). As to the environment, there was an increase in air temperature and temperature-humidity index at the hottest hours of the day, causing discomfort to the birds, which increased respiratory rate, but with the maintenance of homeothermy. Differences were observed in feed consumption, water consumption, production, weight of eggs and mass of eggs, due to the electrolyte levels in the feed. For feed conversion, both per mass and per dozen of eggs, there was no statistical difference. The electrolyte balance and environmental indices at the hottest hours of the day did not affect quail production.Índice de conforto térmico, variáveis fisiológicas e desempenho de codornas alimentadas com redução proteica R E S U M O Objetivou-se, neste trabalho, determinar o efeito do ambiente e do balanço eletrolítico sobre os índices ambientais, fisiológicos e produtivos de codornas japonesas. Utilizaram-se 288 aves distribuídas no delineamento em blocos casualizados com seis tratamentos e seis repetições de oito aves por unidade experimental. Os tratamentos consistiram em uma ração basal com nível de 20,0% PB e os demais com redução de 3,0% PB, para alcançar seis níveis de balanço eletrolítico (166,54; 153,47; 139,63; 139,63; 117,13 e 166,49). Quanto ao ambiente, verificou-se uma elevação na temperatura do ar e no índice de temperatura e umidade nos horários mais quentes do dia, causando desconforto às aves, que elevaram a frequência respiratória, porém com a manutenção da homeotermia. Foram observadas diferenças no consumo de ração, consumo de água, produção, peso e massa de ovo, em razão dos níveis eletrolíticos da ração. Quanto à conversão alimentar tanto por massa quanto por dúzia de ovos, não foi observada diferença estatística. O balanço eletrolítico e os índices ambientais nos horários mais quentes do dia não interferiram na produção das aves.

“…Despite the fact that the use of more energy efficient lamps has been advocated in recent years (ROSSI et al, 2010;DAVID & ROSSI, 2010;P EREIRA et al, 2012;JÁCOME et al, 2012;BORILLE et al, 2013), some aviary lighting systems are still equipped with a large number of lamps which have high potency and low efficiency. According to PEREIRA et al (2012) the replacement of incandescent bulbs (100 W) for tubular fluorescent lamps T5 (28 W) can reduce by 90.62% the energy demand in broiler poultry to a lighting level of 5 lux.…”

Broiler poultry is highly dependent on artificial lightening. Power consumption costs of artificial lighting systems is the second largest expense related to broiler industry, second only to feed expenses. Therefore, the current study focused to analyze technical and economic feasibility of replacing incandescent lamps already used in aviaries with other lamp types. Costs related to power consumption, implementation and maintenance of the lighting systems were evaluated with the aid of financial mathematics using net present value, return over investment and payback. Systems composed of six lamp types were analyzed in two different configurations to meet the minimum illuminance of 5 and 20 lux and for use in conventional sheds and dark house. The lamps tested were incandescent (LI) of 100 W, compact fluorescent (CFL) of 34 W, mixed (ML) 160 W sodium vapor (SVL) of 70 W, tubular fluorescent T8 (TFL T8) of 40 W and tubular fluorescent T5 (TFL T5) of 28 W. For the systems tested, it was found that the tubular fluorescent lamps T8 and T5 showed the best results of technical and economic feasibility. KEYWORDS:Economic analysis, Poultry farming, Energy efficiency, Artificial lighting. ANÁLISE TÉCNICO-ECONÔMICA DE DIFERENTES SISTEMAS DE ILUMINAÇÃO PARA AVIÁRIOS DE FRANGOS DE CORTERESUMO: A produção de frangos de corte é altamente dependente do uso de luz artificial. O custo do consumo de energia elétrica do sistema de iluminação artificial constitui a segunda maior despesa relacionada à produção de frangos de corte, inferior apenas às despesas com ração. Portanto, objetivou-se com o presente trabalho analisar a viabilidade técnico-econômica de se substituir a lâmpada incandescente utilizada nos aviários por outros tipos de lâmpada. O consumo de energia e os custos de implantação e de manutenção dos sistemas de iluminação foram avaliados com auxílio da matemática financeira, por meio do valor presente líquido, da taxa de retorno do investimento e do tempo de retorno do capital (payback). Foram avaliados sistemas compostos por seis tipos de lâmpada, em duas configurações diferentes, para atender às iluminâncias mínimas de 5 e 20 lux e para a utilização em galpões convencionais e dark house. As lâmpadas testadas foram a incandescente (LI) de 100 W, a fluorescente compacta (LFC) de 34 W, a mista (LM) de 160 W, o vapor de sódio (LVS) de 70 W, a fluorescente tubular T8 (LFT T8) de 40 W e a fluorescente tubular T5 (LFT T5) de 28 W. Para os sistemas testados, verificou-se que as lâmpadas fluorescentes tubulares T8 e T5 apresentaram os melhores resultados de viabilidade técnica e econômica. PALAVRAS-CHAVE:análise econômica, avicultura, eficiência energética, iluminação artificial.
