Performance, Skeletal traits, and welfare indicators of four laying hen strains in aviary housing under common management

Key Points

• Performance indicators showed significant variation among the four laying hen strains, impacting overall yield.
• The skeletal traits measured highlighted differences, with strain performance varying based on welfare indicators observed.
• Assessment using welfare indicators, performance metrics, and skeletal traits, represents comprehensive strain evaluation.
• The findings may enable better management practices, improving both animal welfare and production efficiency in aviary systems.
