The aim of the current study was to evaluate cardiac status, ascitessusceptibility, thyroid hormones, some hematological parameters andperformance of five commercial broiler strains.Chicks were selected from strains of Cobb, Hubbard, Ross 308, Arbor Acres, and Arian (Iranian commercial broiler strain). Management and nutritional conditions were the same for all strains. Ascites related factors, and growth performancewere measured. The highest and lowest, RV weight/live weight at 21 day of age were related to Arian and Ross 308 strains, respectively (p 0.05). Ascites mortalities in the Ross 308 was zero; however, it had no significant difference with other strains (p >0.05).It was concluded that, based on performance and physiological status, even though considered broiler strains did not differ significantly because of the same genetic programs probably, but according to the prices and market conditions each can be selected for breeding.
