The aim of this investigation was to compare the utilization of phosphorus from different sources: from dicalcium phosphate, monocalcium phosphate, with or without phytase enzyme, at a reduced level of the phosphorus source mentioned. The investigation was conducted on the total of 440 fattening chickens of the Arbor Acres strain divided into 4 groups according to the phosphorus source. The trial on the chickens nutrition lasted 42 days. Production traits, i.e. body weight and weight gain, were used as phosphorus utilization criteria in this paper. The study results showed that the highest production results (P is less than 0.05) were obtained with the chickens fed 0.1% phytase feed supplements at a reduced level of the mineral phosphorus source.
