The present paper aims to present the aggressive behavior of broiler breeder males against females and its consequences. The research took place in a breeding poultry farm and the objectives were: to identify and describe the specific lesions found in females and to observe the behavior of the roosters in relation to the females in order to identify behavioral patterns. In the study, 15 corpses were examined and the specific lesions of aggression were described, analyzing the location, extent and acute or chronic nature of the wounds. Thus, it was found that the main areas where the lesions were found, are the head and torso and from the point of view of depth, superficial and deep lesions were identified. Another aspect observed was the clear differentiation of lesions caused by aggression from those caused by cannibalism. Following the behavior observation sessions, it was found that the courtship behaviour of the roosters was poor expressed or even missing, which led in forced mating, and resulted in the described lesions.
