Abstract

Lighting significantly influences broiler chicken growth and feed efficiency. This study evaluated four lighting durations: P0 = control (24 hours), P1 = 18-hour program, Intermittent Program 1, and Intermittent Program 2. Key parameters measured were mortality, feed conversion ratio (FCR), harvest tonnage, and performance index. Results showed significant impacts of lighting duration on all parameters. P0 had 3.87+-0.48% mortality, 1.68+-0.01 FCR, 40+-0.49 tons harvest tonnage, and 291+-10.30 performance index. P1 showed 3.94+-0.10% mortality, 1.71+-0.02 FCR, 40+-0.27 tons harvest tonnage, and 357+-5.21 performance index. P2 had 4.80+-1.18% mortality, 1.53+-0.03 FCR, 52+-0.50 tons harvest tonnage, and 388+-0.67 performance index. P3 had the best results with 1.54+-0.60% mortality, 1.43+-0.04 FCR, 49+-1.08 tons harvest tonnage, and 407+-4.10 performance index. Statistical analysis (P-value < 0.05) confirmed significant effects of lighting duration on all parameters. With a P-value of 0.000, carcass quality improved significantly, showing no bruising, making the meat suitable for export. Proper lighting management enhances broiler production and carcass quality.
