Abstract

The study was conducted from September to October 2025 at the Poultry Facility of IFTO – Dianópolis Campus to evaluate the effect of different stocking densities on the behavior of broiler chickens and assess its impact on productive performance in an intensive rearing system in southwestern Tocantins. A total of 80 birds was distributed in a completely randomized design with four stocking density treatments (2, 4, 6, and 8 birds m⁻²) and four replications. Behavioral assessment was carried out through instantaneous sampling every 10 minutes, from 6 a.m. to 6 p.m., on October 2, 16, and 30, totaling 36 hours of observation. The behaviors evaluated were idleness, sitting, feeding, drinking, scratching, and feather pecking. There was no significant effect of the treatments on the behaviors analyzed (P > 0.05), indicating that the birds adapted to the tested conditions. The results demonstrate that, under proper management and equitable access to resources, the evaluated stocking densities do not compromise the expression of natural behaviors in broiler chickens.
