Abstract

|
For the identification of the Jeju black cattle, Hanwoo and imported beef, we performed a multiplex polymerase chain reaction (PCR) associated with microsatellite (MS) and melanocortin 1 receptor (MC1R) gene. The MC1R gene plays an important role in regulation of the melanin synthesis within mammalian melanocytes. MC1R encoded by extension (E) locus was almost fixed with recessive red e allele in the Hanwoo. We estimated that the specific genotypes (E+/E+, E+/e) of MC1R gene were characteristic genotypes of Jeju black cattle. But the PCR products resulted from using the MC1R gene derived primers only are not sufficient to identify Jeju black cattle from other relatives. We performed two times of successive multiplex PCR to provide a more accurate result for the identification of Jeju black cattle. The results suggest that two types of successive multiplex PCR methods using MC1R gene and Microsatellite derived primer set will be more useful to identification of Jeju black cattle, Hanwoo and imported beef.
