Abstract :Aim of the study was to evaluate the effects of diet non-phytate phosphorus insert ignore into journalissuearticles values(P); and calcium insert ignore into journalissuearticles values(Ca); level on growth performance and some blood, bone and faeces parameters of broilers. A total of 480 one-day-old Ross 308 broilers were randomly allocated to 3 dietary treatments with 5 replicates for a 42-d study. Corn-soybean meal based diets were consisted of three different Ca and P concentrations for starter and grower periods. High, medium and low Ca and P levels in starter and grower periods were 1.05-0.49, 0.95-0.44, 0.85-0.41% and 0.87-0.42, 0.78-0.38, 0.69-0.34%, respectively. After the first 21-d feeding period, no differences were observed for feed intake insert ignore into journalissuearticles values(FI); but body weight insert ignore into journalissuearticles values(BW); and feed conversion ratio insert ignore into journalissuearticles values(FCR); were higher insert ignore into journalissuearticles values(P 0.05);. Fecal ash, tibia and sternum weight and sternum ash were not affected from the Ca and P concentrations but tibia ash was lower insert ignore into journalissuearticles values(P 0.05);. However, alkaline phosphatase insert ignore into journalissuearticles values(ALP); enzyme activity was higher insert ignore into journalissuearticles values(P<0.05); in group having medium levels of Ca and P. Based on the data, it can be concluded that 8.5 g/kg Ca and 4.1 g/kg P can be used for starter period without any deterioration on growth performance.
