ABSTRACT

Three types of feed phosphates: monocalcium (MCP), dicalcium (DCP), and calcium-sodium (CSP), were used in Lohmann Brown laying hens feeding. The content of macro- (Ca, P, Mg, Na) and microelements (Cu, Fe, Zn) in blood serum of birds was determined at a peak and in final phase of laying period. Dicalcium phosphates (DCP) significantly increased mean content of phosphorus when compared to CSP, calcium in relation to MCP, and iron when compared to both phosphates (MCP and CSP). Monocalcium phosphates (MCP) in turn, significantly increased concentration of copper when compared to DCP. Generally, more macroelements (except sodium) and microelements were observed in blood hens in the final phase of laying period, when compared to the first phase of laying period (peak).

Key words: hen, phosphate, blood, mineral profile.
