Prion octapeptide-repeat polymorphism in Polish Black-and-White cattle

Krzysztof WALAWSKI, Urszula CZARNIK

Abstract: The study was carried out in a Polish Black-and-White cattle population, represented by 167 AI sires, 200 young tested bulls, 190 bull-dams, and 606 randomly chosen cows from commercial herds. The fragment of the bovine prion protein gene (PRNP) coding the octapeptide-repeat sequence, was identified by PCR analysis. Two different gene variants of 349 bp and 373 bp in size, produced three genotypes: PR

Key words: Black-and-White cattle, octapeptide-repeat polymorphism, prion protein.
