초록
This study was conducted to investigate the effect of parity and region on the live body charateristics of Hanwoo cows. The data used were logissimus muscle area (LMAU), back fat thickness (BFTU), marbling score (MSU), and p8 point fat thickness (P8 FTU), by ultrasound from 1,239 heads of hi-lok branded Hanwoo cows. Based upon ultrasound characteristics of LMAU, BFTU, MSU and P8 FTU were significantly high in Hanwoo cows in Hwacheon area. Live body characteristics were increased with the parity, however estimated value tended to decreased after sixth parturition. Also, comparative of pre or after parturiti- on on the live body characteristics, pre parturition value showed little lower than after parturition
