ABSTRACT
In the Korean meat market, the native cattle, Hanwoo beef, are preferred over imported beef and domestic Holstein beef despite its relatively high price. In order to hold the beef industry accountable and support consumers' right to know, correct beef-origin labeling is required. For this purpose, we developed 90 single-nucleotide polymorphism markers to discriminate between Hanwoo and other breeds including Holstein using 1602 cattle DNAs. The probability of discrimination was found to be 100% in a subsequent validation set consisting of 632 DNAs. Our study suggests that improved beef-origin discrimination can be achieved by using a combined genetic model that takes into account small genetic differences among a large number of markers. These markers could be useful for discriminating between Hanwoo and imported breeds including domestic Holsteins, and would contribute to the prevention of falsified beef origin.
