Abstract
In this study the effect of diet dilution in 16-20 d of age and using a multi-enzyme (Endofeed-W) on performance, carcass characteristics and some blood parameters of broiler chickens (Cobb 500, commercial strain) was studied. This experiment was conducted as a factorial arrangement 2×3 in a completely randomized design with 3 replicates and 8 chicks in each replicate. Experimental diets contained 0, 20 and 40 percent rice hulls and 2 levels of enzyme (0, 500 mg/Kg). These diets contained 3000, 2400, 1800 Kcal/Kg metabolizable energy, and 21, 16.8 and 12.6 % crude protein, respectively. In other days of experiment, the chicks were fed in according to Cobb 500 rearing guideline. During feed restriction and whole period of rearing (1-44d), diet diluting up to 20% decreased feed conversion ratio (P
