Background: indigenous breeds are important for poor farmers because of their natural selection against harsh environments and adaptation to regional conditions. However, inbreeding sheep populations has increased in Colombia due indiscriminate cross-breeding with foreign animals lack reproductive controls, subsequent loss productivity, which poses a great risk the conservation valuable genes. Objective: determine genetic diversity Colombian by using panel 10 microsatellite molecular markers. Methods: blood samples from 362 individuals 43 farms 11 provinces were genotyped analyzed Results: total 134 alleles found (13.4 alleles/locus on average) range observed expected heterozygosity 0.428 0.831 0.615 0.855, respectively, 0.742 polymorphic information content (PIC). The average Wright F-statistics (FIS) was 0.107, suggesting moderate levels inbreeding. showed low level differentiation among (FST = 0.054) STRUCTURE analysis complex patterns admixture breeds. Conclusion: overall, have high variability, is very future programs improvement.
