“…Currently, the Criollo Caqueteño cattle have a low number of females with reproductive capacity [6][7][8]. With the development of next-generation sequencing (NGS) technologies, and single-nucleotide polymorphism (SNP) annotation, studies on population history, genetic diversity, and genome structure in domestic animals became possible [9][10][11][12][13]. This technology has been applied to cattle to study aspects such as the evolutionary history and genetic structure of different breed populations [14].…”

Evolutionary mechanisms have shaped the genomic architecture of Colombian Creole cattle breeds. The mating and selection processes have impacted several traits, promoting differences within and between populations. Studies of population structure and selection signatures in Colombian Creole breeds are scarce, and need more attention to better understand genetic differentiation, gene flow, and genetic distance. This study aimed to analyze the population structure and identify selection imprints in the Criollo Caqueteño (CAQ) population. It used 127 CAQ animals genotyped with Chip HD 777,000 SNPs. The population structure analyses used discriminant principal component analysis (DAPC), integrated haplotype scoring (iHS), and index-fixing (Fst) methodologies to detect selection signals. We can highlight SNP regions on the genes TMPRSS15, PGAM2, and EGFR, identified by the Fst method. Additionally, the iHS regions for cluster 1 identified candidate genes on BTA 3 (CMPK1 and FOXD2), BTA 11 (RCAN1), and BTA 22 (ARPP21). In group 2, we can highlight the genes on BTA 4 (SLC13A4, BRAF), BTA 9 (ULBP), BTA 14 (CSMD3) and BTA 19 (KRTAP9-2). These candidate genes have been associated with fertility traits, precocity, growth, and environmental and disease resistance, indicating a genetic potential in CAQ animals. All this promotes a better understanding of the diversity and genetic structure in the CAQ population. Based on that, our study can significantly assist the sustainable development and conservation of the breed in the Colombian Amazon.

“…There is no legal definition of an autochthonous/native/traditional breed in the country and no legal criteria are set for the recognition of an endangered breed. However, references to generally accepted autochthonous or traditional breeds can be found across the literature (Oravcová et al, 2006;Weis and Hrnčár, 2009;Šidlová et al, 2015;Kadlečík et al, 2017). While a common understanding of autochthonous breeds was also reported in Poland, Austria has a more precise definition, which includes breeds having a herdbook in Austria before 1938, or ample evidence that they have always been present and bred in a part of Austria, or stem from the Austro-Hungarian monarchy and have had relations to regions of Austria (Kompan, 2014).…”

To effectively conserve animal genetic resources, countries need to periodically review their conservation efforts and reflect on actual problems and challenges. This study provides a review of animal genetic resources conservation activities, as well as the related existing legislative measures, strategies and funding in Slovakia. We present the development of endangered and supported breeds, discuss the impact of subsidies and the importance of awareness raising, and provide a SWOT analysis of the current animal genetic resources conservation framework in the country. In Slovakia, conservation is primarily based on animal breeding in natural conditions (in situ) without any limitations to breed improvement, and cryoconservation of animal genetic resources is in its initial phase. Most of the funding for conservation measures is provided by the Rural Development Programme. In general, the animal genetic resources system in Slovakia is open in terms of including new breeds eligible for support and this paper shows that the provided subsidies helped to stabilize most of the supported populations. Promoting the presence, characteristics and advantages of local breeds in times of intensive import of exotic breeds into the country is crucial to motivate breeders to prefer local livestock breeds. While the future challenge for the government is to improve conservation and facilitate related activities, research should address not only diversity, pedigree studies and cryoconservation, but also focus on the characterization of animal genetic resources for food security and climate change.

“…With the development of nextgeneration sequencing technologies (NGS), the annotation of single-nucleotide polymorphisms (SNPs) has been routinely employed to infer population history, genetic diversity, genome-wide association, and genome structure in domestic animals (Gautier et al, 2007;Decker et al, 2014;Mastrangelo et al, 2014;Edea et al, 2015;Šidlová et al, 2015). Among livestock species, this technology has been successfully applied in cattle thanks to many factors such as evolutionary history, genetic structure, and economic conditions, which render cattle particularly suitable for the application of genome-assisted selection (Nicolazzi et al, 2014).…”

In Colombia, different dairy breeds were introduced from Europe and the United States, which underwent different crossing and selection processes that generated specific qualities or differences and which likely have their own genomic structure. To characterize genetic diversity, population structure, and admixture, we used genotypes from 23,182 autosomal single nucleotide polymorphisms (SNPs) of 130 animals representing four dairy cattle breed groups from Nariño. In addition, we merged genotypes from 43,043 autosomal SNPs, from 137 animals from the Decker database (Decker et al., 2014) (DRYAD doi:10.5061/dryad.th092). After the quality control process of pruning the merged dataset, we were left with 7,475 autosomal SNPs shared by both databases of Nariño (127 samples) and Decker (135 samples). Genetic diversity levels were moderate in all breeds (average observed heterozygosity = 0.40). Based on the fixation index values, we conclude that Brahman individuals were more differentiated than the taurine breeds (-0.374 to 0.076 for Brown Swiss). Pairs between taurine breeds showed low genetic differentiation (0.011-0.479). Principal component analysis revealed that in both the Nariño and Decker databases, the taurine formed the most compact cluster compared with other breeds known not to share the same ancestry, and Jersey, Brown Swiss, and Normand individuals exhibited high similarity with Holstein individuals. Hierarchical cluster analysis with Admixture revealed that Brahman, Jersey, Normand, and Holstein from the Decker databases most of which were clustered together with the dairy breeds of the Nariño highland tropics are not able to create different groups, thus having greater similarity with each other. This can be explained by the crosses made by farmers to increase milk production volume, always based on the Holstein breed with semen of bulls from America and Canada. Detrimental impacts due to intensive selection might cause some specific traits from the region to be fixed in the offspring, which can influence their adaptive capacity to the highland tropics.
