Abstract: The experiments were performed on Lohmann Brown Classic hens hybrid, fed five formulas (NC) containing different calcium and phosphorus levels, with or without phytase addition: NC1 and NC2 were commercial formulas; NC3 did not include any mineral phosphorus but was added Phyzyme (500FTU/kg NC), NC4 contained monosodium phosphate, while NC5 contained monocalcium phosphate. The density of the eggshells was different between the experimental groups; NC3 achieved an aP (available phosphorus) concentration of 0.30% due to phytate hydrolisis by Phyzyme. In comparison to phosphorus from monosodium phosphate, the aP from NC3 showed a biological value of 91.19%. The calcium and phosphorus content of eggshells in formulas NC3, NC4 and NC5 did not show any statistically significant differences (p>0.05). In the group fed the NC3 formula, phosphorus excreta was up to 20% lower than in the other experimental groups. The serum alkaline phosphatase levels did not show any statistically significant differences between groups. There is a positive correlation (p<0.005; r=0.871) between the level of serum alkaline phosphatase and the phoshorus content of eggshells in group NC3, while serum phosphorus and phosphorus content in eggshells do not correlate statistically significant (p>0.005; r=-0.763), where the significance threshold is r=0.811.
