Light wavelength and its impact on broiler health.

Light is a powerful management tool in poultry production systems, affecting productivity, physiology, and behavior. The objective of this study was to understand the impacts of three light colors (blue, green, or white) on broiler health. Broilers (N = 14,256) were raised in floor pens with fresh litter from 0 to 35 d in 9 rooms (2 blocked trials).

Light color and the commercial broiler: effect on behavior, fear, and stress.

Light is an important component in poultry production, and it may impact bird behavior, an important component of animal welfare. Light-emitting diode (LED) lamps are of interest for broiler production since they are inexpensive to run and provide monochromatic colors. This study aimed to understand the impact of three light colors (blue, green, or white), provided by LED lighting, on behavioral expression, stress and fear levels of broilers.

Does light color during brooding and rearing impact broiler productivity?

Light color during brooding and rearing may impact broiler production; however, literature results are inconsistent. To address this, the effects of 3 wavelength spectra on broiler performance in 2 sex and 2 genotypes (Ross YPMx708 and EPMx708) were studied. Broilers were raised (d 0-35) under wavelength programs provided by LED light bulbs (blue (455 nm), green (510 nm) or white) under similar intensities (clux).

Light Color and the Commercial Broiler: Effect on Ocular Health and Visual Acuity.

Light is a critical management factor for broiler production, and the wavelength spectrum, one of its components, can affect bird physiology, behavior and production. Among all the senses, sight is important to birds, and their visual system possess several adaptations that allow them to perceive light differently from humans. Therefore, it is critical to consider whether the exposure to monochromatic light colors influences broiler visual ability, which could affect behavioral expression.
