Poultry are sensitive to red objects, such as comb and blood on the body surface, likely inducing injurious pecking in flocks. Light is an important factor that affects the pecking behavior of poultry. A wooden box was built to investigate the effects of Light Emitting Diode (LED) light color (warm white and cold white) and intensity (5 and 50 lux)...

Highlights An LED-based candling system was designed to automatically judge egg fertility. LEDs of six different colors were tested for light optimization. Relative absorptivity (RA) was negatively correlated with the L * value and positively correlated with the a * value. The results combined with egg parameters produced higher accuracy than the r...

LED has shown great advantages in poultry husbandry. This study focused on the behavioral preferences and production performance of chicken broilers reared under unevenly distributed yellow LED light. Four pens were divided into two groups adopting respective maximum light intensities (MLIs, 60 lx and 30 lx). Because of different distances from the...

Light intensity is an important aspect for broiler production. However, previous results do not provide a solid scientific basis for quantifying the response of broilers to light intensity. This study performed a meta-analysis to model the response of broilers to 0.1 − 200 lux of light intensity. Meta-analysis was used to integrate smaller studies...
