The effect of different levels of lemon pulp and enzyme on performance, caracass traits, immune status and intestinal morphology of broilers

This experiment was conducted to evaluate the effect of different levels of lemon pulp and enzyme in diet on performance, carcass traits, immune status and intestinal morphology of broilers. This experiment was carried out with 288 Ross – 308 broilers as (3×2) factorial arrangement with three levels of lemon pulp (0, 1.5 and 3%) and two levels of Rovabio multi-enzyme (0 and 0.05%) in 6 treatments and 4 replicates (12 birds per replicate) in a completely randomized design from 10 up to 42 days. Using lemon pulp without having any significant effects on the amount of daily feed intake and feed conversion ratio caused the daily amount of whight gain in contrast with group without lemon pulp increased. Adding of enzyme to diet had no effects on performance of broilers (P>0.05). In interaction effects of lemon pulp and enzyme, using lemon pulp with enzyme increased the amount of daily feed intake (P0.05). Using 1.5% lemon pulp increased the amount of broilers blood IGg in 32 days (P0.05). The overall results indicated that in broilers using 3% lemon pulp can improve their performance, immune status and the intestinal morphology, whereas enzyme had no effects in this respects.
