Analysis of Illumina BovineSNP50 BeadChip data in different Italian cattle breeds to identify useful markers for breed authentication of dairy and be…

The identification of the breed of origin of cattle derived products has recently assumed particular relevance since the increasing interest in marketing mono-breed labelled cheese and beef. These products are usually sold at a higher price creating financial incentives to substituting them with lower value products coming from undifferentiated or common breeds or crossbred animals. Frauds can damage these valuable niche markets that, indirectly, may help to preserve genetic diversity through the economic incentive on raising local breeds, derived by the high value products, that are usually less productive. DNA analysis can help to identify fraudulent behaviour as we already demonstrated f…

Conservation status and historical relatedness of Italian cattle breeds

2018

Background In the last 50 years, the diversity of cattle breeds has experienced a severe contraction. However, in spite of the growing diffusion of cosmopolite specialized breeds, several local cattle breeds are still farmed in Italy. Genetic characterization of breeds represents an essential step to guide decisions in the management of farm animal genetic resources. The aim of this work was to provide a high-resolution representation of the genome-wide diversity and population structure of Italian local cattle breeds using a medium-density single nucleotide polymorphism (SNP) array. Results After quality control filtering, the dataset included 31,013 SNPs for 800 samples from 32 breeds. Ou…

A genome-wide perspective on the population structure of Italian cattle breeds

2018

Despite the growing diffusion of cosmopolite specialized breeds, several autochthonous cattle breeds and populations are still bred in Italy. The aim of this study was to provide a high-resolution picture of the genome-wide diversity and population structure of Italian local cattle breeds using medium-density genome-wide SNP markers. After data editing, the dataset included 800 samples from 32 breeds that were genotyped for 31 013 SNPs. For several breeds we observed a low level of polymorphism and genetic diversity, that together with the small effective population sizes confirmed threat of extinction. According to the runs of homozygosity analysis, evidence of recent inbreeding was strong…
