Growth Performance and Some Serum, Bone and Fecal Parameters of Broilers Fed with Different Levels of Calcium and Phosphorus

Aim of the study was to evaluate effects diet non-phytate phosphorus (P) and calcium (Ca) level on growth performance some blood, bone faeces parameters broilers. A total 480 one-day-old Ross 308 broilers were randomly allocated 3 dietary treatments with 5 replicates for a 42-d study. Corn-soybean meal based diets consisted three different Ca P concentrations starter grower periods. High, medium low levels in periods 1.05-0.49, 0.95-0.44, 0.85-0.41% 0.87-0.42, 0.78-0.38, 0.69-0.34%, respectively. After first 21-d feeding period, no differences observed feed intake (FI) but body weight (BW) conversion ratio (FCR) higher (P0.05). Fecal ash, tibia sternum ash not affected from lower (P
