Dietary Melegueta pepper alleviates heat stress-induced disruptions in haematobiochemical parameters, liver histopathology and growth performance indices of broiler chickens in tropical conditions

Key Points

• Broiler chickens exhibited better growth performance and improved haematobiochemical parameters after dietary supplementation with melegueta pepper—indicating stress alleviation.
• The most notable improvement was observed in liver histopathology, showing less damage attributable to heat stress after treatment.
• Assessment involved broiler chickens exposed to heat stress, supplemented with melegueta pepper to evaluate physiological responses and overall health.
• These findings signify potential dietary strategies to enhance chicken health and performance in tropical environments.
