Figure 8: Body temperature (°C) of 81-day-old broilers reared under different lighting system.
From: A new method to manipulate broiler chicken growth and metabolism: Response to mixed LED light system
Each group of treated birds was reared under either cell (replicate) equipped with two green LED lights (G group), cell (replicate) equipped with a green LED light and a blue LED light (G-B group), cell (replicate) equipped with two green-blue-dual-wavelength LED lights (G × B group), cell (replicate) equipped with two blue LED lights (B group), or cell (replicate) equipped with two normal artificial lights (F group as control group; fluorescent lamps) from 1 day old until termination of experiment at 81 day of age. At the end of the trial (81 day of age), body temperature was measured using an infrared thermometer. Data are expressed as mean value ± SEM. Bars marked with different letters are significantly different from each other (P < 0.05).
