Lighting significantly impacts poultry production. Too little lighting during brooding or too much during grow-out can result in lost performance and profits. Solid side wall,tunnel-ventilated poultry barns are more energy efficient to operate but do require artificial lighting sources.The expense of lighting a poultry barn with 60-watt in can-descent bulbs can be as much as 30%-40% of the electrical operating cost($100-$250 a flock/ barn depending on barn size and flock age to market). Therefore, lighting improvements should not only be beneficial for the birds but also energy efficient to minimize production costs.
