Allele frequencies of the major milk proteins in the Finnish Ayrshire and detection of a new kappa-casein variant.
A total of 20990 Finnish Ayrshire cows were phenotyped for the major milk proteins by isoelectric focusing in polyacrylamide gels. The predominant alleles in the Finnish Ayrshire were alpha S1-casein B (0.999), alpha S2-casein A (0.991), beta-casein A1 (0.509) and alpha 2 (0.490), kappa-casein A (0.612) and beta-lactoglobulin B (0.716). The kappa-casein E allele (0.307) was also rather common in the Finnish Ayrshire. A new kappa-casein variant (kappa-casein F) was demonstrated in two Finnish Ayrshire cows, a dam and a daughter.
