In cattle, we observe a decrease trend in the level of reproduction and animal health. This decline is associated with an increase in milk yield. This situation has a negative impact on the farm economy, animal welfare and safety of product. The traditional selection program is in these so-called functional traits ineffective and there is need to find a new ways of animal breeding. In this problematic traits marker assisted selection and the related genomic animal selection is proposed to be a good tool for animal breeding. The present work summarizes the problems of selected functional traits in cattle and provides an overview on genetic markers and possibilities for their use. Further attention is paid to the studied genes and their associations to functional features which have been published in the scientific literature. At the end, the first results are presented describing the genotype frequencies for the first four studied polymorphic regions in Czech Fleckvieh cattle.
