Estimation of heritability and genetic parameters for carcass traits and primal cut production traits in Hanwoo

Currently, the Hanwoo cattle (Korean cattle) industry is improving by selecting superior sires and distributing semen to farms for artificial insemination.This method is highly effective at the national level and has significantly contributed to the development of the Hanwoo industry (Kim et al., 2010).The Hanwoo Improvement Main Center provides information on the major genetic abilities of certified sires (carcass weight, eye muscle area, backfat thickness, and intramuscular fat), as well as conformation traits and the genetic abilities of the top 10 primal cuts through its website and brochures.Consumers' meat consumption patterns are continuously changing, and the Hanwoo industry must produce products that meet consumer demand.Recently, the consumption of preferred meat cuts has intensified, resulting in a wider price gap between different meat cuts (Jeong et
