Replacement value of cassava for maize in broiler chicken diets supplemented with enzymes

Pellet durability, particle size distribution, growth response, tibia bone characteristics and energy retention were measured to evaluate cassava as an alternative energy source to replace maize in broiler diets with or without Ronozyme (A+VP) enzyme composites. A total of 480 one-day broiler chicks were randomly assigned to 8 treatments in a 4 × 2 factorial arrangement. Four levels of cassava: (0, 25, 50, 75%) and 2 levels of enzymes (0 and 500 g/tonne) were used. Each treatment was replicated six times, with ten birds per replicate. The particle size distribution in the diets showed an increasing trend of small particles with increase in cassava level. Pellet durability decreased (p
