  An experiment was conducted to determine the effect of phytase supplementation on old layer hens performance and evaluation of using phytase nutrient equivalency values with comparison to those fed conventional diet. In this experiment 288 Hy-line W-36 hens were used from 60 to 72 weeks of age. The treatments consisted of a control diet (C) without phytase, control diet supplemented with 300 FTU kg-1 phytase over the top (C+P) and the third diet contained 300 FTU kg-1 phytase which calculated nutrient equivalency values for phyatse (100 E). Hen day egg production for the C, C+P and 100 E group were 75.25, 77.25 and 66.0%, respectively. As egg production declined, FCR increase significantly (p<0.05). There were no significant differences in egg specific gravity, egg shell thickness and breaking strength, egg and toe mineralization among dietary treatments. Results indicated that using phytase nutrient equivalency did not prove energy and protein utilization but improved phosphorus utilization in old layer hens.
