Abstract

Background and Objective: The light environment is a critical yet often underappreciated factor influencing poultry physiology, welfare and productivity. This study aimed to evaluate the effects of tetrachromatic full-spectrum PhysLite® LED lighting, designed to mimic the natural visual perception of chickens, on growth performance, physiological stress and antioxidant status in broiler chickens.

Materials and Methods: A total of 60 day-old broiler chicks were randomly allocated to two treatment groups: (1) Conventional white LED lighting (control) and (2) Tetrachromatic full-spectrum PhysLite® LED lighting. Body weight was recorded daily over a 30-day experimental period. On day 30, blood samples were collected to determine serum corticosterone levels and antioxidant indices, including superoxide dismutase (SOD), catalase (CAT) and malondialdehyde (MDA), using enzymatic colorimetric methods.

Results: Broilers reared under tetrachromatic full-spectrum lighting exhibited significantly higher final body weight compared to the control group. Additionally, corticosterone concentrations were markedly reduced, indicating lower physiological stress. Antioxidant analysis revealed increased SOD activity, along with decreased CAT activity and MDA concentrations, suggesting improved redox balance and reduced oxidative stress in birds exposed to PhysLite® lighting. Furthermore, the alignment of the lighting system with the tetrachromatic visual sensitivity of chickens likely contributed to enhanced visual comfort and behavioral stability.

Conclusion: Tetrachromatic full-spectrum PhysLite® LED lighting significantly improves growth performance, mitigates physiological stress and enhances antioxidant status in broiler chickens. These findings highlight its potential as a welfare-oriented and sustainable lighting strategy for optimizing productivity and health in modern poultry production systems.
