Resumo: The objective of this work was to evaluate the phosphorous requirements (Pd) when mono-ammonium phosphate (MAP) is used as a phosphorous (P) source for broilers in the starter phase (1 to 21 days). We used 800 male chicks at one day old, in a 5x2 factorial arrangement, with five AP levels (0.28, 0.34, 0.40, 0.46 and 0.52%) and two Ca levels (1.00 and 0.60), totaling ten treatments and eight replicates. Significant interaction was observed between phosphorus and calcium levels of the diet, in performance traits, bone ashes and P retention and excretion. Utilizing the level of 1.0% Ca in the diet, the best results of performance and bone ashes were found when the levels of 0.42% and 0.439% Pd were used, respectively. Better contents of bone ashes were observed with the use of 0.60% Ca in the diet only when the lowest level of P was used. When MAP is used as a source of P in the diet for broilers in the starter phase, 0.43% of Pd and 1.00% of Ca are enough to promote better performance and bone mineralization.
