Abstract:
One of the main objectives of the present thesis was the merging of pedigree data of the two Austrian Haflinger breeding associations, the ARGE Haflinger and the Haflinger Pferdezuchtverband Tirol. On the basis of the constructed genealogical tables for Haflinger stallions in Austria an analysis of the genealogical development of the seven Haflinger sire lines was performed. In 2015 the A-line was the largest sire line comprising 25 stallions, the S-line with only four stallions remained the smallest. The study showed that restocking of sires was performed unequally in all of the lines and lead to the loss of numerous branches and therefore to a decrease of the genealogic and genetic diversity. The inbreeding coefficient (Fall) in the current sire population for up to 24 generations was at an average of 13,36 %. Generation intervals in all of the seven sire lines are short compared to values from other horse breeds.
