“…We tested an LED light system having a CCT of 3000 K, considered cool because it contains more blue color than the conventional one (CFL, 2700 K). Diodes CCT were cooler (4500-5300 K) than those tested and reported in literature [19] aimed at examining different productions (eggs). A potential positive effect of neutral LED lighting on animal welfare in terms of biochemical parameters was also shown in a study aimed at evaluating the effects of neutral (K = 3300 to 3700), cool (K = 5500 to 6000), and warm (K = 3000 to 2500) LED lightings.…”

“…In a recent review, a comparative analysis of incandescent lamps, compact fluorescent light (CFL), and emitting diodes (LED) found positives and limitations of these three light sources in poultry farming. LED light emerged as the most promising technology to guarantee high growth performances and save energy costs [19].…”

“…This originates from the recombination of electron-hole pairs according to the junction diode principle, characterized by the presence in the device of two suitably prepared parts or areas with opposite electrical traits. A recent review [19] analyzed the light characteristics of the source, intensity, and wavelength of LEDs on different poultry species (chicken, duck, goose, and quail), showing that color and wavelength affected productivity. In a review dedicated to the emerging field of precision lighting [20], LEDs are more often used in livestock houses, providing monochromatic, full-spectrum light comparable with natural daylight in contrast to the previously conventional fluorescent lamps.…”

This study assessed the use of feeders equipped with light-emitting diodes and their effects on the productivity of broiler chickens under productive conditions. A total of 87,200 ROSS 308 chickens, 1-day old, were housed in two poultry houses (CONTROL, F-LED). In CONTROL, 20,000 females (mean body weight 41.12 ± 3 g) and 25,000 males (mean body weight 41.56 ± 3 g) were housed, while 19,200 females and 23,000 males of the same genetic make-up and mean body weight were housed in F-LED under the same environmental conditions. In F-LED, to encourage chickens to feed and to redistribute more feed down the feeding line, a feeder equipped with a LED light has been installed at the end of each line. In CONTROL, no light was located on the feeders. At the end of the cycle, the average body weight never showed significant differences both for females (1345 g in CONTROL; 1359 g in F-LED) and for males (2771 g in CONTROL; 2793 g in F-LED). Uniformity improved in F-LED, at 75.2% in females and 54.1% in males, compared to CONTROL, at 65.7% and 48.5%, respectively, for females and males. The feed conversion ratio followed the same trend, being more favorable in chickens reared in F-LED (1.567) compared to those raised in CONTROL (1.608). The application of a single F-LED at the end of each feeding line demonstrated its utility in improving size uniformity and feed conversion.

“…Thus, it is essential for researchers to report light intensities based on average measurements recorded at the egg level. It is also imperative for researchers to report light intensities in gallilux or chicken lux rather than lux as poultry birds and humans perceive light differently ( Oso et al, 2022a , b ). This is important, especially when photo-incubation extends till hatch or birds are light stimulated post-hatch.…”

The chicken hatching egg is a self-contained life-supporting system for the developing embryo. However, the post-hatch performance of birds depends on several factors, including the breeder management and age, egg storage conditions and duration before incubation, and the incubation conditions. Studies have determined the effect of incubation factors on chick post-hatch growth potential. Therefore, chick physical quality at hatch is receiving increasing attention. Indeed, although incubation temperature, humidity, turning and ventilation are widely investigated, the effects of several variables such as exposure of the embryo to high or low levels, time of exposure, the amplitude of variations and stage exposures on embryo development and post-hatch performance remain poorly understood. This review paper focuses on chick quality and post-hatch performance as affected by incubation conditions. Also, chick physical quality parameters are discussed in the context of the parameters for determining chick quality and the factors that may affect it. These include incubation factors such as relative humidity, temperature, turning requirements, ventilation, in ovo feeding and delay in feed access. All these factors affect chick embryo physiology and development trajectory and consequently the quality of the hatched chicks and post-hatch performance. The potential application of adapted incubation conditions for improvement of post-hatch performance up to slaughter age is also discussed. It is concluded that incubation conditions affect embryo parameters and consequently post-hatch growth differentially according to exposure time and stage of exposure. Therefore, classical physical conditions are required to improve hatchability, chick quality and post-hatch growth.

“…Light intensity, light color, and photoperiod are three light environment factors and changes in these factors will have different effects on the growth of poultry [5,6] . Different light intensities have no significant effect on the performance of broiler chickens, although too high or too low light intensity often affects the welfare of poultry [7][8][9][10][11] .…”

Poultry is a light-sensitive animal and the light environment has an important influence on the growth and development of these animals. Previous studies have mainly focused on the effects of the light environment on various physiological indicators of poultry but seldom explored the light demand characteristics of broilers under free selection. This experiment mainly studied the light demand characteristics of broilers under a yellow LED light environment and the influence of different breeding densities [low-density (2.5 broilers/m 2 ), high-density (7.5 broilers/m 2 )] on the production performance and diet characteristics of broilers. Studies showed that the production performance indexes of low-density groups are higher than those of high-density groups. The feed and water consumption in the light area of the two experimental groups were significantly higher than those in the dark area, which means that the broilers showed a great preference for the light area. However, as the age of the broilers increased, the food and water consumption of the broilers decreased, indicating that broilers had a lower preference for light in the middle and late stages of growth. The statistical results for the residence frequency distribution characteristics showed that broiler chickens had different light requirements at different growth stages under the condition of active selection: 1) low-density breeding environment: 23.8L (light):0.2D (dark) for chicks and 22.3L:1.7D for adult broilers; 2) high-density breeding environment: 22.6L:1.4D for chicks and 15.
