The genetic structure of Ventasso Horse (VH) was investigated using 12 microsatellites. The analyses were carried out on 117 VH individuals and the results were compared with those obtained analysing 11 other breeds reared in Italy. All microsatellites were polymorphic in VH and in the other breeds. A total of 124 alleles (from 6 to 19 alleles per microsatellite) were detected. Average heterozygosity was 0.743 in VH and ranged from 0.613 to 0.759 in the other breeds. The mean F-ST value had an average value of 0.0932. Genetic distances were calculated using Nei's standard genetic distance (Ds). The smallest Ds values were found between VH and Anglo-Arab, Thoroughbred, Maremmano and Lipizzan horse breeds. Phylogenetic trees constructed using neighbour-joining method showed two clear separate clusters: the first includes Bardigiano, Haflinger and Italian Heavy Draught Horse, the second contains the other 9 breeds.

Abstract

The genetic structure of Ventasso Horse (VH) was investigated using 12 microsatellites. The analyses were carried out on 117 VH individuals and the results were compared with those obtained analysing 11 other breeds reared in Italy. All microsatellites were polymorphic in VH and in the other breeds. A total of 124 alleles (from 6 to 19 alleles per microsatellite) were detected. Average heterozygosity was 0.743 in VH and ranged from 0.613 to 0.759 in the other breeds. The mean F-ST value had an average value of 0.0932. Genetic distances were calculated using Nei's standard genetic distance (Ds). The smallest Ds values were found between VH and Anglo-Arab, Thoroughbred, Maremmano and Lipizzan horse breeds. Phylogenetic trees constructed using neighbour-joining method showed two clear separate clusters: the first includes Bardigiano, Haflinger and Italian Heavy Draught Horse, the second contains the other 9 breeds.
