Genomic analysis of Croatian Goats

Native goat breeds in Croatia are considered as an important component of regional biodiversity and are important for the preservation of cultural and traditional heritage. The loss of their genetic diversity could have significant economic, environmental, scientific and social consequences. The aim of this study was to analyse the genetic diversity and conservation status of two native Croatian goat breeds, the Croatian Coloured goat and the Istrian Goat, using genome-wide SNP data. The two breeds are geographically separated, the Istrian goat lives in the Istrian peninsula and the Croatian Coloured goat lives in the area of southern Velebit, Dinara, Kamešnica and Biokovo. Population structure and conversation status were analysed based on 11 Istrian goats and 33 Croatian Coloured goats, as well as an additional 19 breeds of goats and the wild relative Iranian bezoar. The mean observed heterozygosity for the Istrian goat and the Croatian coloured goat was 0.39 and 0.40, respectively. Nei genetic distance with Neighbour- Net graph and PCA were used to reveal population relationships. Istrian goat and Croatian Coloured goat showed that they are two separate breeds. Each of the Croatian native goat breed cluster with different European goat breed. The effective population size calculated with GONE was 5 and 119 and inbreeding level was 0.06 and 0.04, for Istrian and Croatian coloured goat respectively. Despite the lower population size, the two breeds still have relatively high genetic diversity and have potential for a conservation plan in the future.
