This study examined the effects of light intensity and duration in closed broiler barns, comparing traditional and dimmable lamps on broiler performance. Four groups of Arbor Acres female broilers (n=100,000 per group) were subjected to different lighting conditions for 45 days: (A) traditional lamp, 18-24h; (B) traditional lamp, 18-23h; (C) dimmable LED, 18-24h, fixed 56% intensity; (D) dimmable LED, 18-23h, adjusted 20-80% intensity. Body weight (BW), average daily gain (ADG), feed conversion ratio (FCR), and mortality rate (% Mortality) were evaluated using a randomized complete block design. Group D achieved the lowest FCR (1.6) and highest ADG (69.2 g/day), while group A had the highest final BW (2,823.0 g/bird) and lowest mortality rate (1.2%), though differences were not statistically significant (p>0.05). Notably, groups with dimmable LEDs showed higher early-stage mortality. While controlling both light intensity and duration produced the best FCR results, the increased early mortality in these groups necessitates further investigation to optimize lighting programs that balance efficiency and bird welfare, particularly during the critical early growth phase.
