“…Prescott and Wathes (2002) studied feeding preference under different light intensities (<1, 6, 20 or 200 lux) of ISA Brown hens and found that the birds chose to eat most of the time in the brightest condition (200 lux) and the least in the dimmest (<1 lux). Some other lighting preference studies have been done on spectrum (Ham and Osorio, 2007), light source (Mendes et al, 2013), and interaction between light intensity and room temperature (Alsam and Wathes, 1991). In general, light preference of poultry is diversified with different strains and ages.…”

Light intensity, spectrum and pattern may affect laying hen behaviors and production performance. However, requirements of these lighting parameters from the hens' standpoint are not fully understood. This study was conducted to investigate hens' needs for light intensity and circadian rhythm using a light tunnel with five identical compartments each at a different fluorescent light intensity of <1, 5, 15, 30 or 100 lux. The hens were able to move freely among the respective compartments. A group of four W-36 laying hens (23 to 30 weeks of age) were tested each time, and six groups or replicates were conducted. Behaviors of the hens were continuously recorded, yielding data on daily time spent, daily feed intake, daily feeding time, and eggs laid under each light intensity and daily inter-compartment movement. The results show that the hens generally spent more time in lower light intensities. Specifically, the hens spent 6.4 h (45.4%) at 5 lux, 3.0 h (22.1%) at 15 lux, 3.1 h (22.2%) at 30 lux and 1.5 h (10.3%) at 100 lux under light condition; and an accumulation of 10.0 h in darkness (<1 lux) per day. The 10-h dark period was distributed intermittently throughout the day, averaging 25.0 ± 0.4 min per hour. This hourly light-dark rhythm differs from the typical commercial practice of providing continuous dark period for certain part of the day (e.g. 8 h at night). Distributions of daily feed intake (87.3 g/hen) among the different light conditions mirrored the trend of time spent in the respective light intensity, that is, highest at 5 lux (28.4 g/hen, 32.5% daily total) and lowest at 100 lux (5.8 g/hen, 6.7%). Hen-day egg production rate was 96.0%. Most of the eggs were laid in <1 lux (61.9% of total) which was significantly higher than under other light intensities ( P < 0.05). Findings from this study offer insights into preference of fluorescent light intensity by the laying hens. Further studies to assess or verify welfare and performance responses of the hens to the preferred lighting conditions and rhythm over extended periods are recommended.

“…For example, hens can perceive ultraviolet and infrared radiation (Menes et al, 2013). Several works have been conducted (Gougruttananun and Guntapa, 2012;Silva et al, 2012;Jacomé et al, 2012;Hassan et al, 2013;Borrile et al, 2013;Mendes et al, 2013) in order to analyze the effects of different light sources on the egg quality and the performance of commercial laying hens.…”

“…In addition to the wavelength and the light intensity that can vary according to each production phase as well as the type of production, other important principles involved in lighting are: light incidence duration and distribution of light sources (Mendes et al, 2013). These principles can influence positively the performance of the hens (Mendes et al, 2010;Gonguttananun and Guntapa, 2012).…”

“…Incandescent bulbs are commonly used to provide uniform illumination, however its conversion rate from electrical energy to luminous energy is low, which generates a large amount of heat (Jordan and Tavares, 2005;Borrile et al, 2013;Mendes et al, 2013) and provides a low durability, increasing the production costs (Jordan and Tavares, 2005).…”

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.

“…Evaluation results of different LED colors for artificial lighting system in poultry production and their physiological and production effects are found in literature (XIE et al, 2009;ZHANG et al, 2012;MENDES et al, 2013). According to MENDES et al (2010) quality, intensity, photoperiod, and light color may interfere with bird behavior and development.…”

Light emitting diode (LED) use in artificial lighting for broiler chicken production

Light emitting diode (LED) has been used in commercial poultry industry by presenting superior energy savings and providing feasibility on production process. The objective of this research was to evaluate performance and carcass yield of broiler chickens exposed to different LED colors compared with fluorescent lamps. For that, two experiments (E1 and E2) were performed and 2,646 Cobb® chickens were used. In experiment E1, male birds were exposed to 20 lux artificial lighting with red, yellow, blue, and white LED bulbs; and fluorescent bulb. In experiment E2, male and female birds were exposed to 15 lux artificial lighting with red and blue LED bulbs; and fluorescent bulb. Cumulative weight gain (kg), feed intake (kg), feed conversion, hot carcass weight (kg), carcass yield (%), and breast and thigh + drumstick yield (%) were used as response variables. Results showed no difference (p > 0.05) among treatments for performance, carcass yield, and cut yield in experiment E1. In experiment E2 there was only difference between genders (p < 0.05) and males showed higher total weight gain, feed intake, hot carcass weight and thigh + drumstick yield. Different LED color use had same effect as fluorescent lights on broiler performance and carcass yield.
