“…Light colour (wavelength) was reported to have an influence on the plasma testosterone levels in broilers in previous studies (Cao et al, 2008). However, our current result indicated that green light stimuli during embryogenesis did not enhance testis development and testosterone secretion in broiler embryos and hatched male chickens.…”

“…In ovo injection of testosterone prior to incubation reduces 12-dold female embryo weight and protein content of pectoralis superficialis muscle (Henry and Burke, 1999). However, monochromatic green light after posthatch was effective in stimulating testosterone secretion and myofiber growth of broilers (Cao et al, 2008).…”

“…Due to the growth dynamics of broilers after week 5, females were expected to present worse FCR than males, but this trend was not observed in the present study, and both males and females had worse FCR than the standards of their genetic line. When LED was used as light source, the average FCR was 2.29 in week 5, which were lower that the FCR of 3.0 obtained by Cao et al (2008) using white LED light; however, the latter evaluated FCR in week 7. …”

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

“…Charles et al (1992) observed that broiler carcasses have a lower percentage of body fat and higher percentage of body protein following exposure to high-intensity light than those exposed to lowintensity light. Studies by Cao et al (2008) have suggested that the growth and productive performance of broilers are increased under green and blue lights. Other reports have also stated that both blue and green lights are more effective in stimulating testosterone secretion and myofiber growth than increasing the body growth (Rozenboim et al 1999).…”
