dc.description.abstractSUMMARY Background: Local breeds are national treasures and an aim of the saving of such breeds is not only to manufacture local products, preserve ancient knowledge and conserve natural landscape, but transfer historical and cultural values continuously.Objectives: The authors estimated genetic variability and population genetic parameters to support within-family selection of Cikta breed, based on herd-book data. Furthermore, maternal lineages (families) were also identified. Materials and Methods: Pedigree data of the Cikta breed from 2000-2014 were analysed. A reference population from 2011-2014 was chosen to get infor-mation about the current status of the population. The reference population covered a generation interval (approx. 4 years) at the end of the dataset.Results and Discussion: The number of maternal lineages (families) that can be found in the pedigree was 445. This number is of large interest because it is necessary to pick up at least one appropriate female offspring in all the families, applying a within-family selection. The average inbreeding coefficient of the total population was 1.00%, whereas it was 1.16% for the reference stock. Only 476 individuals were responsible for the total genetic variability in the total population which consisted of 3648 animals. There were nine ancestors with the largest contribution to the total genetic variability, however, none of them exceeded 10% of the genetic variability. Effective number of founders was 44 whereas effective number of ancestors was 42 for the total population. It was 39 and 36 for the reference stock, respectively. The longest generation interval estimated for the dam-to-son pathway.en_US
