초록
The objective of this study was to differentiate the beef species between Hanwoo and Holstein from a total of 1,081 beef samples using PCR-RFLP of MC1R gene. When a PCR product of 403 bp specific band amplified from bovine MC1R gene sequence was digested with restriction enzyme MspA1I, Hanwoo type showed 2 bands, 220 bp and 183 bp size bands. Holstein type, however, showed three bands, 220 bp, 138 bp and 45 bp size band, respectively. The results of the differential test for beef species were as following; 7 samples (0.64%) were determined to Holstein type, of which 4 were submitted from administrative authorities, other 3 from self-collection planing, and none from civilian clients including school.
