Polymorphism of 11 micrasatellite DNA loci was analysed in Polish Red (PR), (Hereford and Holstein-Friesian (HF) cattle raised in Poland and genetic distance among these breeds was determined. At the 11 loci (TGLA227, BM2113, TGLA53, ETH10, SPS115, TGLA126, TGLA122, INRA23, ETH3, ETH225 and BM1824) analysed with automated DNA sizing technology, a total of 213 alleles were identified: 76 in PR, 76 in HF, and 61 in Hereford. All the microsatellite DNA markers showed high polymorphism. Polymorphism information content (PIC) calculated for each marker exceeded 0.5, except for the ETH3 locus in Hereford cattle (PIC=0.475), and heterozygosity (H) ranged from 54.1 % to as much as 85.2%. The coefficient of genetic distance was 0.354 between PR and Hereford, 0.414 between HF and Hereford, and 0.416 between PR and HF cattle.

On the basis of DNA microsatellite polymorphism at 26 loci tested within the European Concerted Action AIRE 2066 for the Analysis of Genetic Diversity to Preserve Future Breeding Options, a determination was made of the genetic structure of 147 Polish Red (PR) cattle, included in the National Rare Livestock Breeds Preservation Programme (NRLBPP). The examined PR cattle population was characterized by a high genetic variation (a total of 193 alleles identified, Ho = 0.695, He = 0.703,mean number of alleles per locus = 7.4). An analysis of the genetic distance (Dps), including information on the presence (or absence) in the genome of alleles specific for the breed, confirmed that 80% of PR animals included in the NRLBPP comprised a separate genetic group, differing from populations of other European cattle breeds. The results show the uniqueness of the gene pool of PR cattle included in the NRLBPP. Despite the crossing with other breeds widely applied in the past, the present PR material does, to a considerable degree, remain genetically distinct. Thus, it is anticipated that basing on the existing preserved population the reconstruction of a pure, or almost pure PR cattle can be achieved.

The prevention of transmissible spongiform encephalopathy (TSE) in humans and animals has become an important element of safe food production. Part of the studies connected with this problem concentrate on the search for potential markers of the susceptibility or resistance to bovine spongiform encephalopathy (BSE). The present report presents a characteristic of the bovine prion protein (PRNP) gene polymorphism within the population of european bison and two endemic cattle breeds – Polish Red (PR) and Polish Whitebacked (PWb), the latter two included in a genetic resources conservation programme.European bison appeared monomorphic as regards PRNP what was reflected by the presence of only one genotype – PRNP 6/6. In the northern (lowland) subpopulation of PR the frequency of PRNP 6/6 and PRNP 6/5 genotypes was 0.926 and 0.074, respectively. In the PR southern (sub-montaneous) subpopulation the share of PRNP 6/5 and PRNP 5/5 was 0.214 and 0.049. In the PWb cattle the frequency of PRNP 6/6 was 0.628, that of PRNP 6/5 – 0.321, and of PRNP 5/5 – 0.051.
