The aim of this study was to analyze the reproduction and breeding status of 1655 Hanwoo (Korean cattle)cows raised in Gangwon East area (Gangneung, Taebaek, Donghae, Yangyang, Samcheok, Sokcho, andGoseong). The average age in months and the parity of Hanwoo was 43.6 and 1.7 respectively. Registrationstatus of the cows were 42.0% (pedigree), 30.2% advanced), 20.0% (fundamental), and 4.0% (non-registry).Korean proven bull's number (KPN) 517 and KPN 588 were preferred 25.8%, 16.2% respectively for artificialinsemination (AI) of the cows. Appearance rate of over 1st meat quality grade in the offsprings obtained fromAI of top 6 KPNs was 90% which was above national average (slaughters only 77.81%, total 63.12). Resultsindicated genetic influence the KPN for meat quality grade of their offspring. Strong correleation between AIfailure rate of mother cows and their offspring cows has been observed. KPN information, meat quality grade,and AI failure percentage would be quite useful factors to understand their relationship in further improvementof Hanwoo in Gangwon East area.
