Implications of Caesalpinia sappan Linn. extract supplementation on growth performance, carcass traits, meat quality, intestinal morphology, and antioxidant and immune-related gene expression in Thai native crossbred chickens

Key Points

• Meat quality improved significantly with caesalpinia sappan extract supplementation, enhancing overall growth.
• Key metrics reveal a notable increase in carcass traits and antioxidant levels, supporting better health.
• Assessment of gene expression indicated enhanced immune-related responses alongside improved intestinal morphology.
• Findings highlight the potential for caesalpinia sappan as a natural growth promoter in poultry, warranting further trials.
