초록
Analysis of meat quality grade based on the DNA identity test samples were done on 320 Hanwoo (Korean cattle) raised in Gyeonggi region of Korea. 62.29% of cows and 91.35% of steers showed high quality which was above 1st beef grade. However, differences were observed between Gyeonggi Hanwoo and total slaughtered Hanwoo in Gyeonggi in the year 2009, though the sampling was entirely based high quality meat. Meat samples of pedigree registered cattle showed high rate of above 1st meat grade compared to advanced and fundamentally registered cattle. Pedigree registry is associated with quality grade of beef like the sex of cattle. Appearance rate of above 1st beef grade in offsprings of the top 9 Korean Proven Bulls produced through mating to Gyeonggi Hanwoo was 43.27% which was found to be higher than the average grade in cows (47.3%)and was 13.08% higher than the average grade in steers (77.49%). Our results showed superior genetic characters of Korean Proven Bulls which favors and influence the meat quality grade of their offsprings. Furthermore, our results claim that sex of Hanwoo irrespective of pedigreed or Korean Proven Bulls affects and/or influence the meat quality. Conclusively, the results could therefore be used as a basic data for the improvement of beef quality. However, paternity test by DNA typing and huge sample needs to be analysed to authenticate the findings.
Abstract
Analysis of meat quality grade based on the DNA identity test samples were done on 320 Hanwoo (Korean cattle) raised in Gyeonggi region of Korea. 62.29% of cows and 91.35% of steers showed high quality which was above 1st beef grade. However, differences were observed between Gyeonggi Hanwoo and total slaughtered Hanwoo in Gyeonggi in the year 2009, though the sampling was entirely based high quality meat. Meat samples of pedigree registered cattle showed high rate of above 1st meat grade compared to advanced and fundamentally registered cattle. Pedigree registry is associated with quality grade of beef like the sex of cattle. Appearance rate of above 1st beef grade in offsprings of the top 9 Korean Proven Bulls produced through mating to Gyeonggi Hanwoo was 43.27% which was found to be higher than the average grade in cows (47.3%)and was 13.08% higher than the average grade in steers (77.49%). Our results showed superior genetic characters of Korean Proven Bulls which favors and influence the meat quality grade of their offsprings. Furthermore, our results claim that sex of Hanwoo irrespective of pedigreed or Korean Proven Bulls affects and/or influence the meat quality. Conclusively, the results could therefore be used as a basic data for the improvement of beef quality. However, paternity test by DNA typing and huge sample needs to be analysed to authenticate the findings.
