The Sarcidano Horse, an autochthonous breed from Sardinia, is gaining attention in conservation efforts due to its semi-feral lifestyle and genetic isolation. This breed offers important insights into the genetics of equine populations that have remained largely untouched by modern breeding practices.
1. Study Overview
A recent study aimed to deepen the understanding of the Sarcidano Horse, specifically its coat color genetics. The focus was on two genes, MC1R and ASIP, which are responsible for determining the basic coat colors: bay, black, and chestnut.
70 horses were sampled for DNA analysis, and the study found the following:
-
The chestnut coat color was the most prevalent.
-
A smaller number of horses had black coats, with very few exhibiting bay coats.
-
There was no evidence of color dilution or spotting, suggesting that the population has remained genetically isolated, with little to no crossbreeding with domestic breeds.

2. Implications for Conservation
The lack of coat variations commonly associated with domesticated horses further supports the hypothesis that the Sarcidano Horse has not been affected by human selection. The breed’s genetic isolation and lack of crossbreeding are vital for its conservation, as they help preserve its unique genetic makeup.
Given the breed’s ancient origins and current genetic isolation, experts recommend a regional conservation plan. This plan would focus on:
-
Regular health and genetic monitoring of the population.
-
Collaboration with research centers and universities.
-
The collection and management of DNA, sperm, and embryos to support long-term conservation efforts.
3. Conclusion
The Sarcidano Horse represents an important genetic resource, offering valuable insights into the history and evolution of equine species. Continued efforts to preserve this breed, through both genetic research and conservation initiatives, are crucial to maintaining its genetic integrity and safeguarding it for future generations.
