Abstract :An experiment was conducted to determine the effect of stocking densities (13, 19 and 25 birds/m2) and type of anticoccidial agent (cygro, avatec, amprol plus and capindol) used in the ration on the broiler performance. The research was conducted in 3x4 factorial arrangement with three replicates (in 36 pens with 1.8 m²). A total of 1224 unsexed broiler chicks were used in the experiment. They were reared in a windowed conventional house until 8 weeks of age and fed starter diet from 0 to 4 weeks of age and finisher diet from 4 to 8 weeks of age. Feed and water were provi ded for adlibitum access. Coccidial agents were withdrawn from ration at the last week of the trial. Body weight of brollers at 8 weeks of age which were reared at high density (25 birds/m2) were significantly decreased from the broilers were reared at other densities (p<0.01). Weight gain from 0 to 8 weeks of age and carcass weight were depressed, when stocking densities were increased, but differences among the groups were not significant. When stocking densities were increased, feed intake and feed/ gain ratio of broilers were significantly reduced (p <0.01) and mortality was slightly increased. It was observed that the brollers were fed cygro, and avatec generally give the lowest performance characteristics. None of the coccidial agents used in the ration didn\\\'t significantly effect the carcass weight and mortality. The effect of Interaction on the feed consumption in different stage of growth and feed/gain ratio from 0 to 4 weeks of age were not found consistently.
