The use of LED lights in broiler house to boost production.

Electricity is one of the largest expenses for poultry producers aside from feed cost and this is increasing thus alternative sources of lighting are explored. Solar bulbs have been used on farms and also electricity generated from biogas,both of which have been successful. A recent study explored the use of LED bulbs and its potential to boost production and cutting electricity bills.Light-emitting diodes (LEDs) may be a good choice of energy-efficient lighting for broilers and their producers, according to this recent research. Researchers from the University of Delaware evaluated the effects of cold cathode fluorescent lamps (CCFLs) and two types of LED lamps in a study with more than 670 male Ross broilers, while birds raised under incandescent lamps served as controls. By 42 days of age, birds raised under CCFLs had lower body-weights than controls and had higher heterophil-to-lymphocyte (H:L) ratios a stress indicator. In contrast, using LEDs did not yield any significant differences in the H:L ratio compared to controls. This study indicates that variation in broiler body weight and stress may be attributed in part to lighting technologies implemented in broiler houses, while birds raised under both LED technologies grew to body-weights similar to birds raised on incandescent lamps, but there were no significant differences between the groups in feed conversion or mortality.
