Animal biodiversity in connection to food resources availability

- significant impact on the functioning of the surrounding food systems and livelihoods
- ensures numerous ecological functions and directly contributes to well-being, nutrition and food security
- in connection to livestock, it makes agricultural production systems more resistant to shocks and stresses, including those caused by environmental changes
- in recent decades, a significant decrease of livestock biodiversity has been demonstrated mainly concerning local populations
Is the biodiversity level of selected local cattle populations considered as important food resources in Slovakia sufficient for their sustainable use in the future?
- dual-purpose (Slovak Pinzgau, Slovak Spotted) and beef breeds (Charolais, Limousine)
SNP data & QC
- Illumina BovineSNP50 BeadChip, International Dairy and Beed chip
- QC – PLINK 1.9: autosomal SNPs and animals with minimum call rate 90% and minimum minor allele frequency 1% retained in dataset
- PLINK 1.9; FROH computed based on the scan of runs of homozygosity segment with different length in the genome of breeds
Effective population size
- SNeP; historical and recent NeLD derived from the functional relationship between linkage disequilibrium level in the genome of breeds and effective population size
Genetic differentiation and selection signatures related to immune response
- R package pcadapt; selection signatures derived based on principal component analysis
- The highest intensity of relatives mating in current generation of Slovak Pinzgau cattle reflects the rapid decline in population size during recent years
- Analysis of genome structure revealed specific haplotypes strongly associated with genetic nature of each breed studied
- The loss of biodiversity was most evident in genomic regions included in the genetic control of economically important traits.
