<br/><br/> Three experiments were carried out to study the effects of reducing dietary nitrogen and phosphorus and/or adding enzymes to different broiler diets on performance, carease characteristics, bone measurements and excretion of N, Ca and P. The first experiment examined the effect of reducing dietary crude protein level and adding avizyme (xylanase, protease and amylase) 1g/ kg diet
