Poultry lighting
Light is an essential aspect of poultry production. In most housing systems, artificial light is utilized to maximize production in pullets, layers and breeders. Today, a variety of different bulbs are available to illuminate the inside of a poultry house, all of which have benefits and shortcomings. Understanding the different lighting options available for poultry, as well as the terminology and management of light, is essential to achieve the best production. Light is critical for egg production and pullet growth. Domestic poultry see and respond to a different range of light color spectrum and have different spectral intensity responses than humans. While humans respond to light from around 400–750 nm, chickens can see UV-A light (315–400 nm) in addition to 400–750 nm. Additionally, the magnitude of sensitivity for red and blue spectra is much higher for chickens with additional peaks of light sensitivity around 480 nm and 630 nm.
INTRODUCTION Avian embryogenesis is a perfect platform to examine the effects of exogenous factors on embryonic development due to the physiological independence from the hen (Hill et al., 2004). During incubation, the management of cabinet temperature, humidity, egg turning and air composition are critical to achieving successful artificial incubation. Light is an important exogenous factor for controlling many physiological and behavioral processes in animals but the use of...

Looking for a golden goose? Try a goose that’s two years old. In a recent study, researchers with the Heilongjiang Academy of Agricultural Sciences found that goose egg yolks (the most valuable part of the egg) tend to be at their largest following the goose’s second laying season.

Light plays an important role in controlling the age at sexual maturity in birds; attaining sexual maturity at an appropriate age and weight is the key to reproductive success and the present study was an effort in the same direction. To develop specific practice for quail production and to optimize the best age for photo-stimulation present experiment was conducted. In total 225 females and 75 males of 5 week old were studied. A completely randomized design with three treatment of 5...

Providing an optimal light program during pullet rearing and breeder production starts with understanding how chickens are stimulated by light. Light intensity, light coloring and day length all play a major role in preventing or stimulating sexual maturation. Ideal day length for rearing pullets is 8 hours to prevent early sexual development and therefore assure that flocks begin lay and maintain egg production in a more uniform manner....

INTRODUCTION Genetic selection programs emphasizing broiler growth, breast muscle deposition, and feed efficiency traits over the past 30 yr have led to a rate of change that has not slowed (Havenstein et al., 2003a,b). Photostimulation ( PS ) age, feed allocation, and BW profile of the maturing pullet can all effect nutrient partitioning between growth and ovary development (Robinson et al., 2007). Renema et al. (2007b) reported that, as a percentage of BW, Ross 708...

INTRODUCTION Despite superior color vision, hue discrimination, and motion detection, broiler chickens are typically kept in lighting conditions deemed suitable for humans. Environments tailored to poultry vision could lead to improvements in bird health, welfare, and performance by supporting the development of normal vision and in male broilers (Edwards, 2003). UVB exposure also improved bone mineral density, egg production, and levels of vitamin...

A grow light is the artificial light provided to the livestock for their growth and development. It is used to modify the physiological & biological responses of an animal with respect to feeding habits, reproduction, and milk production.
Livestock grow light technology is a known technology; it has wide usage in livestock farms. The use of smart technology in livestock farms is expected to witness robust growth and adoption during the forecast period, owing to the increase in...

KEY POINTS Birds ‘reproductive cycle is controlled by changes in day length called as Photoperiod. Birds perceive this photoperiod in two ways: a) Through retinal of the eye to visual cortex and pituitary gland b) Through harderian gland (UVA specific light) which triggers reproductive system Birds are not “stimulated” by the entire period of light, but rather by two important parts of this period. Birds are...

Introduction
Despite domestication and intensive genetic selection, commercial poultry retain the need to perform their natural behaviours. Conventional broiler housing often provides little opportunity for a good range of natural behaviours, while conventional layer cages severely restrict normal movement and behaviour. Damaging behaviours have been shown to increase in chickens when they are deprived of...

INTRODUCTION The influence of light is a resultant of period, intensity, and colour and wattage power of the lamp. Classen and Riddell, 1989 [4] suggested that birds exposed to increasing photoperiod appeared to be more active. Several workers have examined the effect of light programme on physiological stress of broilers. Buckland et al. (1976)[2] found higher concentrations of plasma corticoids in broilers housed under...

LIGHTING LAYERS Intensity In natural light (window) housing the natural light is supplemented with 1.5 - 5.0 fc for the period when supplemental lighting is used. It has been found that birds exposed to very dim lights, say 3 hrs at.02 -.03 fc) prior to exposure to bright lights, say 8 hrs at .5 fc or more, might perceive this as sunrise and daylight and shift their biological clock as if exposed to 11 hours of normal light. However, the reverse, dim following bright, does not shift their...

The role of light in biological activities associated with avian growth and reproduction is very well known. Light quality can be defined by three criteria: 1) daily pattern of lightdark exposure; photoperiod, 2) light intensity (brightness), and 3) spectral composition (Andrews and Zimmerman, 1990).

Implementation of lighting programs adapted to the normal growth rate of chickens, has brought about improvements in the viability of the animals, feed conversion and decrease of physiopathological dysfunctions, such as: Ascites, skeletal problems and sudden death, depending on the duration of light exposure (Abad, 2005). However, prolonged or continuous exposure to light,...
