This research aims to evaluate how alpha-amylase supplementation influences energy utilization and intestinal health in broiler chickens on reduced-energy diets.
Utilized a completely randomized design with 640 male Cobb 500 broiler chickens.
Administered four dietary treatments with varying amounts of alpha-amylase.
Assessed performance, carcass yield, and nutrient digestibility at 21 and 42 days.
Broiler chickens receiving 200 g of alpha-amylase per kg of diet exhibited better energy utilization compared to control groups.
Enhanced nutrient digestibility and intestinal morphology were observed in the 200 g alpha-amylase group.
Increased concentrations of beneficial short-chain fatty acids were noted in the caeca of chickens supplemented with 200 g alpha-amylase.
