Allelic frequency of PCR-RFLP type of the BoLA-DRB3 in Japanese Holstein herds and the relation to mastitis

Abstract excerpt

Holstein Cows (n = 702) from 26 dairy herds in the Tama area of Tokyo, Japan were examined for polymorphisms of the BoLA-DRB3 allele using a PCR-RFLP method. Twenty alleles were observed and allelic frequencies ranged from < 1% to 20.3%. Nine alleles (DRB3.2*24,*16,*8,*23,*22,*3,*11, *10 and *7 in order) constituted 90.0% of all alleles. Somatic cell counts (SCC) were used to classify healthy (group 1), mastitis (...
