title: [Breeding strategies to increase fitness in poultry].
abstract: The performance of the meat type hybrids of today is much higher than at the beginning of the century. Antagonistic relations between the polygenic performance traits and fitness are the reason why modern hybrids need optimal management conditions, their susceptibility to stress increased and their immunocompetence decreased. There will be discussed, how modern genetics is counteracting by using new selection techniques.
