Abstract
This study was conducted in a factorial arrangement in complete randomized design (4×2) with 320 one-day old Ross broiler chickens for investigation effect of different level of olive pulp and enzyme on performance and nutrients digestibility for 42 days. The treatments were included: 4 levels of olive pulp (0, 5, 10 and 15% dry matter) and two levels of supplemented enzyme (0 and 0.5% DM) with 4 replicates for each treatment and 10 birds in each replicate. The olive pulp caused to significant increased of intake and gain of broilers (P
