SUMMARY
Agriculture and climate are highly interdependent. Light-emitting diode (LED) is a climate-friendly bulb that has been considered as a promising replacement for conventional lighting in poultry production due to its efficient energy utilisation. Poultry responds to different light characteristics such as source, intensity and wavelength. The review on the effect of LED bulb on different species of poultry birds revealed that there is a knowledge gap on the effects of LED bulbs characteristics on turkeys. Also, there is a dearth of information on the impact of LED on ducks, geese and quails. However, studies on broiler production showed that the effect of LED light on birds can be influenced by wavelength, correlated colour temperature (CCT), age, sex and season of the year. LED bulbs can safely be used as a replacement for conventional lights since no advert effect of LED light has been highlighted in the literature. It has generally been observed that monochromatic green and blue light colour accelerate growth performance in broiler birds. Green and blue colour mixing/switch at certain stages of production further boost the growth performance compared to single colour lighting. The effect of light spectrum in poultry has not been fully explored. Future researches can bridge the knowledge gap on the effect of ultraviolet light spectrum on different poultry species and the use of poultry-specific LED adapted for avian spectral sensitivity can be further researched.
