Research Note: Effect of Various Light Sources on Broiler Performance and Efficiency of Production Under Commercial Conditions

Field trials were conducted in commercial broiler houses to test the effects of various light sources (incandescent and fluorescent) and light intensity on BW, feed conversion, mortality, condemnations, field defects, electrical usage, and electrical costs. Light sources included: 15- and 40-W incandescent lamps; 5 and 9-W compact, fluorescent lamps; and 40-W, 1.2-m fluorescent tube lamps. Type of lamp had no significant effect on bird performance measurements but did directly affect light intensity and lighting electricity costs. Light intensity was adequate in all instances and did not affect performance. Fluorescent lamps significantly reduced lighting electricity costs without any detrimental effect on broiler performance in comparison to standard low wattage incandescent lights.
