Overview

This observational study examines the impact of red and white lighting on laying performance in hens, suggesting light color may influence production variables.

Key Points

  • Hens exposed to white light showed significantly heavier ovaries, indicating a potential advantage in reproductive health.
  • No significant differences were found between red and white lighting in egg production and quality measures.
  • The study evaluated various production metrics including egg weight, feed conversion, and albumen height among 7680 hens.
  • Significant effects on shell thickness and strength were assessed, highlighting the comprehensive evaluation of treatments.
