Popis: The aim of this study was to investigate the influence of different stocking densities on the growth performance of Ross 308 broiler chickens up to six weeks of age. A to tal of 216 one - day broiler chicks were randomly assigned to three treatment groups based on the stocking density: Low (LSD) = 14 chickens m - 2 , Medium (MSD) = 18 chickens per m 2 and High (HSD) = 22 chickens m - 2 , with four replications. Higher body weight gain (TWG) was observed for the low (2,043.89 g) and medium (2 , 008.03 g) compared to the high (1,901.51 g) density. The study revealed that chickens of the LSD treatment consumed significantly ( P < 0.01) more fe ed compared to the HSD chickens. High stocking density (22 m - 2 ) tended to improve feed conversion ratio compared to medium (18 m - 2 ) and low (14 m - 2 ) stocking density, but the differences were not significant ( P > 0.05). From the results of this study it can be concluded that broiler chicks can be stocked up to 22 chickens m 2 , as far as required standards are assured.
