| description | Istrian goat is an autochthonous Croatian breed which inhabited Istrian peninsula and was important in milk production and human nutrition, especially for poor people. For centuries Istrian goat was a recognizable heraldic symbol of Istria, but in her real form almost disappeared from the breeding area. The revitalization and reaffirmation of Istrian goat began with several dozen remaining breeding animals, after a decade-long breeding ban. Genetic characterization of the Istrian goat population is necessary for providing insight into the state of genetically preserved structure within population as well as positioning Istrian goats within phylogenetically related breeds. Microsatellite and mtDNA analysis of reproductive individuals of Istrian goat and related breeds, Croatian White goat and Saanen goat was carried out. In the population of Istrian goat, higher allelic variability (nA = 9.7; AR = 7.4) were found as well as significant genetic distance (FST = 0.068 - 0.086) in relation to other two breeds. Such results indicated that Istrian goat constitutes a separate genetic identity. The observed ten haplotype sequences of the D-loop mtDNA also confirm the significant genetic richness of the maternal hereditary component. The observed haplotypes in the population of Istrian goat belong to lineage A. A smaller number of haplotypes shows similarity to the group of “white” goats, indicating traces of earlier limited but targeted crossing of Istrian goats. The genetic profile analysis of Istrian goats indicates a high level of genetic variability and provides guidelines for a long-term conservation program. The preserved genetic and promising potential of milk production of Istrian goat makes a significant basis for her economic reaffirmation. Orientation of the breed towards milk production could be an efficient strategy for its effective preservation. |
