Abstract. Aspirations to simultaneously increase the level of production and improve the quality of chicken meat create a necessity to jointly assess commercial lines of broiler chickens with respect to many different characteristics. Carrying out separate assessment for each examined characteristic most often leads to obtaining each time different results of comparisons. Because of this, there increases the role of an application of multidimensional comparative analysis, that is methods and techniques of comparing multi-characteristic objects. In the present work the multidimensional comparative analysis was applied to simultaneously compare eight commercial lines of broiler chickens according to seven characteristics. It was found that the best ranks were obtained for the Cobb 500 line. The lowest rank was assigned to the Ross 508 line.
