In poultry farming, artificial lighting is a tool which can, when applied properly, greatly enhance performance and therefore profitability. An artificial lighting system in a barn has three characteristics--color of the light (wavelength), intensity of the light, and the amount of time the lights are on each day (daily photoperiod). With the development of LED technologies, farmers can now simultaneously vary the color, intensity and photoperiod of the lighting in animal houses and barns. This is important because many scientific studies have demonstrated that simultaneous management of these three components can greatly improve poultry production. Traditionally, the artificial lighting in a barn has been limited to incandescent, fluorescent or high-pressure sodium lamps. These lamps have fixed intensity and fixed color; therefore, szAMB installed the only controllable variable is the length of daily light exposure (photoperiod). With LEDs, two more characteristics of the lighting can be manipulated, thus giving new tools for farmers to increase productivity and improve animal welfare. Indeed, it has been reported that skillful application of LED lighting systems can increase net profit by 70-80% (Mauricio Lopez O ., 2018).


In farming, it is important to understand how different animals receive information from the light in their environment because light stimulation is one of the key environmental cues for initiation and synchronization of many physiological processes in an animals body (i.e. reproduction). The type of light in its environment also affects an animal’s behavior, such as feeding activity; the animal’s physiological processes, such as rate of growth; as well as overall condition (i.e. stress levels). Humans receive information about the light in their environment through their eyes only; this is called retinal stimulation. However, other animals receive information about the light in their environment through their eyes AND through other sensors in their bodies. Overall, these structures are called “extra retinalphotoreceptors. Different animals have different extra retinal photoreceptors (Foster & Soni, 1998; Vigh et al., 2002)


What kind of color is good for hens to improve the production ?


By Agricultural Engineer, The Canada Plan Service. Light levels (intensity or illuminance) and the duration of light (photo period) are important factors in poultry production. Intensity has an effect on cannibalism and aggression, along with feed and water intake, while photo period influences reproductive and egg production cycles, total feed intake, and growth rate.


Light intensity at the working plane (bird level, egg collection table, work-bench level, etc.,) is measured in lux or foot-candles (10 lux equals about one foot-candle). 
Typical light levels found in broiler and layer operations are about 10 to 20 lux (1 to 2 foot-candles), while a bright sunny day in mid-summer is about 80,000 lux (8,000 foot-candles). Typical light levels on the surface of an office desk might be 400 to 500 lux (40 to 50 foot-candles). 
Variation of the photo period is used to stimulate egg production in pullet flocks for both breeding and commercial layers. In broilers (chickens and turkeys), several different lighting programs are being studied to help improve skeletal development through feed intake. 
All lighting programs that use more hours of darkness than the hours of darkness during natural day length require light traps on fans and air inlets. 

The following tables provide some of the most common lighting programs for different types of poultry operation
