The examination has been carried out on the 440 fattening chickens, of Arbor Acres strain. There were four experimental groups, considering the different sources of phosphorus added into diet: K - control group (110 chickens - dicalcium-phosphate - 2%); O-I group (110 chickens - monocalcium-phosphate - 1.4%); O-II group (110 chickens - dicalcium-phosphate 1% + 0.1% phytase); O-III group (110 chickens - monocalcium-phosphate 0.7% + 0.1% phytase). The feeding experiment lasted for 42 days. As the criteria of phosphrus utilization, in this work, the bone weight (aitch bone) are shown. The gain results show, that the largest weight of dry and fatless aitch bone had O-II (4.6198 and 3.8453 g), followed by O-III (4.5927 and 3.6901 g), which gained per diet phytase enzim (P is greater than 0.05).
