Crioulo Lageano (CLAG) is a Brazilian taurine breed traditionally raised in the native fields of mountainous regions in the states of Santa Catarina and Paraná, located in the southern region from Brazil. The present study aimed to analyze the genetic diversity and structure of the breed to provide the basis for the development of strategies for its conservation. Samples from semen and DNA previously stored in the Brazilian Animal Gene Bank (BAGB), and samples collected from eight different farms registered in the Brazilian Association of Crioulo Lageano Cattle Breeders (ABCCL), were genotyped with different panels of SNP markers containing between 50 K and 777 K markers. Obtained estimates of average expected (HE = 0.373) and observed (HO = 0.382) heterozygosities suggest the presence of high levels of genetic variability in the breed. Molecular analysis of variance (AMOVA) revealed that only 2.11 % of the observed genetic variation could be attributed to differences between analyzed populations. Obtained pairwise FST estimates varied between 0.002 and 0.056, corroborating that the degree of differentiation between populations is low. Population structure analyses showed substructures between the studied populations, which could be related to the presence/absence of horns in the animals, in addition to other factors. The estimates obtained for the effective population size (Ne) considering bulls with semen stored in BGAB and the set of samples from the eight studied farms were 6 and 22, respectively, revealing that the Ne of the breed is far below that recommended by FAO for conservation of domestic animal populations. Population structure and admixture analyses comparing CLAG with six other taurine and zebu cattle breeds routinely raised in the region revealed evidence of possible unknown introgressions from animals of indicine origin. Obtained results provide solid insights into the diversity and genetic structure of the Brazilian CLGA breed and offer strategic information for the establishment of effective genetic management strategies for production herds, for the enrichment of the BAGB by collecting germoplasm and for the long-term conservation of this breed.
