“…Light, for instance, is a critical environmental factor for manipulating the feed intake. By artificially increasing the length of time the bird is subjected to light, its feed intake can be increased; a technique employed in modern poultry systems to favour high growth rates (Olanrewaju et al 2006;Karakaya et al 2009). It is possible that improved housing conditions (ambient temperature and humidity, air flow etc.)…”

Artificial selection of broiler chickens for commercial objectives has been employed at an unprecedented magnitude over the recent decades. Consequently, the number of days, total feed and in turn energy, required to raise a broiler to slaughter weight, have decreased dramatically. Feed provision is the poultry industry's biggest environmental hotspot; hence, understanding the interactions between the birds' genetic change and their energy use efficiency forms the necessary starting point for quantifying and predicting and thereby mitigating the future environmental impact of the poultry sector. This review assesses the consequences of artificial selection on the following traits: digestive efficiency, body composition and utilisation of metabolisable energy for growth and metabolic activity. The main findings were (1) the digestive system has been subjected to much physical change due to selection in the recent decades, but this has not led to any apparent change in digestion efficiency. (2) Both the energy intake per day and the metabolic heat production rate have increased in the recent decades whilst (3) the efficiency of utilising energy for growth has also increased; this is due to an increased growth rate, so that broilers reach slaughter weight more quickly and therefore need to allocate less energy overall to metabolic processes, with the exception of growth. (4) There may have been a reduction in the tendency to waste feed through spillage and carry out energetically expensive behaviors. There is a discrepancy in the literature with regards to the influence of selection on body composition and its contribution to feed efficiency. In this review, two scenarios are demonstrated, whereby body composition either has or has not altered via artificial selection. Understanding the effects of artificial selection on the traits that relate to the feed efficiency of the broilers will contribute towards the reduction of the environmental impacts that arise from such systems.

“…Varity of previous conducted studies demonstrate the effects of light criteria on bird health and immunity with special references to light color and spectrum, Rozenboim et al (1999) found that maximization of monochromatic light effect on growth and welfare in broiler chickens is achieved by age of birds, also, Karakaya et al (2009) found that rearing broiler under green light at an early age and blue light in older one could improve growth performance and meat quality properties, while, Rozenboim et al (2004) stated that switching light from blue to green at 20 day age could improve growth performance of male broiler chickens. Moreover, Xie et al (2008) found that immune response of broilers was enhanced under green and blue light.…”

Key words:Behavior, Broilers, Fear Response, Monochromatic LED Light, Performance.The present study aimed to investigate the effect of rearing avian broiler under different monochromatic LED light color on their growth performance, physiological and fear responses. One hundred and thirty five unsexed day-old avian 48 chicks were randomly allocated into three light treatment (n=45 bird) each treatment 3 replicates (n=15 bird). The treatments were white, green, and blue light. The obtained results demonstrated that, broilers reared under blue and green light had higher body weight, weight gain, feed intake, carcass weight, carcass percent, hemoglobin, red blood cells, packed cell volume, total leucocytes count, lymphocytes, total protein, albumin, globulin and lower feed conversion ratio, bursa, liver, spleen relative weight, heterophils: lymphocytes ratio, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase compared with white light. Moreover, blue and green lights reared birds showed short tonic immobility duration and high levels of exploration in the open field test. In conclusion, rearing broilers under blue and green light for 23 h per day improve growth performance, physiological response, welfare, reduce stress and fear responses.

“…This suggests that green light may be required for broiler growth. 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.…”

“…Other researchers also obtained better broiler performance with colored lights. Karakaya et al (2009), for instance, found significantly higher feed intake, body weight and total muscle weight in broilers reared under green light or combined blue and green light compared with those reared under white incandescent light. This suggests that green light may be required for broiler growth.…”

“…After that date, only fluorescent lamps, more efficient than incandescent bulbs, will be available, but are the only source of the use of mercury that will grow in the years to come, because fluorescent bulbs contain Hgdust and vapor, harmful to both humans and the environment when inappropriately disposed (Pawlowski, 2011). Compared with other light sources, the Light Emitting Diodes (LED) have long life (50,000 hours) and low power consumption, there are evidences that they may improve broiler productivity (Karakaya et al, 2009). Broilers reared under green LED showed better performance and muscle growth (Rozemboim et al, 2013).…”

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
