“…In study of Karakaya et al(2009), only female broilers were used and performance in response to light is expected to be different between males and females, as found in the present study. Santana et al (2014) did not find any broiler performance differences when LED or fluorescent light were used. The main difference in the present study was detected when EEI was evaluated, as it allows comparing overall parameters.…”

The purpose of this study was to evaluate the effect of green monochromatic light emitting diodes (LED) or white fluorescent lamps on the growth performance of broilers reared in open houses. Two hundred broilers (Ross 308) were sexed and divided into four treatments, according to sex and supplemental light source: T1, males under green LED; T2, males under fluorescent lamps; T3, females under green LED; and T4, females under fluorescent lamps, totaling 50 birds per treatment with five replicates each (n=10). Broilers of both sexes received natural light during the day and supplemental lighting (fluorescent or LED) during the night, according to age. Individual body weight, mortality, and feed intake were recorded weekly per replicate. Feed conversion ratio and the European Efficiency Index (EEI) were calculated. Data were analyzed by a two-way ANOVA. The results indicated differences (p< 0.05) in female body weight in week 6, (2202.31 ± 32.93g green LED vs 2191.08 ± 62.13g fluorescent lamp), but no differences in daily weight gain, feed conversion ratio, or mortality were detected. However, the use of green LED promoted higher EEI in males in weeks 5, 6, and 7, and in females in week 5 (p < 0.05). Green monochromatic LED may be used for supplemental lighting of male broilers reared in open houses with natural light. Its use for female broilers is recommended if the birds are marketed up to 5 weeks of age. IntRoduCtIonBroiler production systems of broilers present different management and facility characteristics, leading the producers to apply alternatives to increase production efficiency. Among the features that enable sustainability of animal production systems, the highest productivity per area is essential, making of environmental control a key component of farm profitability. Artificial lighting programs have a proven influence on weight gain and feed conversion ratio (Abreu et al., 2011), because they can be used as an exogenous element for the control of physiological and behavioral processes. Their manipulation modulates circadian rhythms, body temperature, and feed intake and digestion in poultry. Lighting is necessary for the bird's vision, influencing visual acuity and color discrimination (Calvet et al., 2009). Light color modifies the patterns of secretion of hormones related to growth, maturation, and reproduction (Olanrewaju et al., 2006).The lighting process consumes a significant part of the electrical energy used on the farm. Fossil fuels used for electric power generation are becoming more difficult and expensive to obtain, and produce CO 2 emissions to the troposphere (Peñuelas and Carnicer, 2010). Additionally, Mexico's government regulation established that incandescent bulbs are would not allowed to be sold after December 554

“…Furthermore, proper positioning of light sources and their distribution in the shed encourages birds to seek food, water, and heat during the rearing phase. For Santana et al (2014) the use of LEDs has been highlighted in aviculture because it presents energy savings and provides viability of the breeding process.…”

Brazil occupies a privileged position worldwide in poultry farming. The economic activity is recognized as necessary for the country's GDP and also has a significant climatic diversity. Because of this, different types of aviaries were and still are built in the national territory. The objective of this study was to present a systematic review of the factors that have an impact on the intensive production of broiler chicken based on the scientific publications since the year 2000. The literature review showed a constant evolution and the knowledge about the form of housing that best expresses the genetics of birds. It was found that the thermal environment, air quality and other factors related to the housing of broiler chickens significantly imply in their performance.Keywords: thermal comfort, ambient cooling, flock density, broiler genetic strains. FATORES QUE AFETAM A PRODUÇÃO DE FRANGOS DE CORTEO Brasil ocupa uma posição privilegiada em todo o mundo na produção de frangos de corte. A atividade econômica é reconhecida como necessária para o PIB do país, que também possui uma expressiva diversidade climática. Por isso, diferentes tipos de aviários foram e ainda são construídos no território nacional. O objetivo deste estudo foi apresentar uma revisão sistemática dos fatores que têm impacto na produção intensiva de frangos de corte com base nas publicações científicas desde o ano 2000. A revisão da literatura mostrou evolução constante e conhecimento sobre a forma de alojamento que melhor expressa a genética dos frangos. Verificou-se que o ambiente térmico, a qualidade do ar e outros fatores relacionados ao alojamento de frangos de corte impactam expressivamente no desempenho.Palavras chaves: conforto térmico, refriamento de ambiente, linhagens genéticas de frangos.* Irenilza

“…Environmental lighting technology has greatly advanced in the recent years, and traditional light bulbs are being gradually replaced by light emitting diode (LEDs) lamps (Gongruttananun and Guntapa, 2012;Santana et al, 2014). The main advantage of the LED is the energy saving (80% less energy waste as compared to incandescent bulbs and 50% compared to fluorescent lamps), longer shelf life and color diversity (Molino et al, 2015).…”

The Brazilian poultry production currently has a substantial impact on the national and international economy. Brazil ranks sixth in the world rankings of the largest egg producers. However, the activity still has barriers related to management and facilities, such as high waste of electrical energy due to the low energy efficiency of the lighting systems. The artificial lighting programs represent an important management tool to accelerate or delay sexual maturity of laying, stimulate the release of reproductive hormones, increase the egg production, besides promoting improvements in the shell quality and the size of the eggs. There is a large number of lamps that are available for use in artificial lighting systems, however, each light source has different characteristics (light intensity, wavelength, color, temperature and fluctuations) which may cause positive or negative effect on hens performance, egg quality and production costs. The LED technology is an innovative alternative that can improve the sustainability of the activity, since it has better energy efficiency, longer lifetime and emits light of different colors. This literature review aims to discuss the beneficial characteristics of the LED and its effects on the production of commercial layers.
