초록

Background: The climate of Korean peninsula is characterized by four distinct seasons. In recent years, global warming has accelerated, and summers in Korea are typically hot and humid. However, the precise extent of climatic damage caused in Hanwoo farming has not yet been reported, by long raise periods. This study was conducted to investigate the effects of birth and slaughter season on economical carcass characteristics in Hanwoo cattle. Methods: Hanwoo steer carcass data was collected from the Korean Institute for Animal Products Quality Evaluation database for 2021-2022. Hanwoo birth and slaughter season was classified as spring (March-May), summer (June-August), fall (September-November), and winter (December-February). Results: The carcass mass and loin area were significantly higher in winter- and spring-born Hanwoo than in summer- and fall-born cattle. However, back fat thickness was significantly higher in winter- and spring-slaughtered steers than in summerslaughtered cattle. In addition, the marbling score was highest in summer-slaughtered steers, but meat yield grade differed between Hanwoo steers of different ages. Conclusions: Out results indicate that carcass mass and loin area were correlated with birth season, whereas back fat thickness and marbling score were related with slaughter season. These results will contribute to improving meat production quality in the Hanwoo industry.
