The association between microsatellite Bm6438 and milk performance traits in Polish Holstein-Friesian cattle

The objective of this study was to verify the hypothesis postulating the location of QTL linked marker for milk performance traits in the proximal section of chromosome BTA1 by analyzing the micro - satellite BM6438 alleles from heterozygous sires and the milk performance traits of the investigated cattle. The experiment covered 484 Polish Holstein-Friesian primiparous cows, the progeny of three unrelated sires, including 317 cows - the progeny of two sires with 256/268 genotype and 167 cows - the progeny of a sire
