Sažetak
All over the Europe, the number of draft horses has been drastically decreased during last 100 years. As a required pre-step for making efficient management decisions, we analysed conservation status of Austrian (Noriker Horse Salzburg-S, Noriker Horse Carinthia-K), Croatian (Posavina Horse-P, Croatian Draught Horse-H) and German (South German Draught-G, Black Forest Horse-B, Schleswig Draught Horse-C, Rhenish Draught Horse-R, Mecklenburg Draught-M, Saxon Thuringa Draught-T, Altmaerkisch Draught-A) draught horses using genotypic information for 30 microsatellite loci in 434 horses. A posterior Bayesian analysis provided answers to three specific hypotheses. First, political division of Germany in 1945 caused small by notable separation of R from A, M and T populations. Second, geographical border (Alps) did not caused notable fragmentation between K and S populations. Third, the lack of precise pedigree information, time difference in subsides and meat price favouring larger horses have caused imprecise classification between H and P populations. Classical distance and multivariate analyses with graphical presentations showed that analysed populations form five groups, although further differentiation within groups were possible. The "Norik" group (G, K and S populations) and the "Renish" group (A, M, R, and T populations) were the most distinctive groups. The "Croatian" group (C and P populations) was in the middle while B and C populations were distinctive, forming separate two groups. Microsatellites were powerful in making correct assignments to the originally defined populations (more then 80%), especially between main five horse groups (almost 100%). The information obtained should aid in making efficient conservation strategies and policies
