The present study was conducted to test whether a multi-enzyme produced by a fungus would keep performance of broiler chicks receiving a diet with almost 3% less nutrients (energy, protein, amino acids, calcium and phosphor) under two different housing density. In both experiments, positive control received standard broiler diet, negative control received a diet with 3% less nutrients than standard broiler diet and enzyme group received the negative control diet+supplemental enzyme. In the first trial with 1000, day-old chicks housed 10 birds/m(2), only 1% improvement in feed conversion efficiency and body growth was achieved with enzyme supplementation in contrast to the negative control at the end of 35 days feeding period. In the second trial with 1200, day-old-chicks accommodated 16 birds/m(2). The results showed that enzyme improved broiler performance almost 3.5% in contrast to the performance obtained from the negative control. In conclusion, supplementing broiler diets based on maize/soya with a multi-enzyme produced by a single fungus provides a great potential to gain the gap created by formulating almost 3% nutrients reduction in broilers housed with 16 birds/m2 density. However, providing high comfort and better rearing condition as the birds at 10 birds/m(2) density, positive effects of the enzyme was limited.
