Authors in their experiment decreased the usual 0.7% broiler respectively layer feeds P-content to 0.55-0.40, respectively 0.55-0.45% at the utilization of phytase promoted not only the utilization of the P, but also the better digestibility of protein and starch, therefore the production results improved. The decrease of P-content of feeds, at the supplementation of phytase enzyme it did neither influence the P and Ca content of the tibia and egg shell nor the stability on the egg shell altered.
