Integrated crop–livestock farming systems improve the self-sufficient feed ratio, and provide environmental benefits foragro-ecosystems. This study was conducted to evaluate the crop-livestock recycling indicators of Korean Hanwoo farms. 55 Koreanbeef farms were classified into five types. Organic Hanwoo farms were insufficient the area of forage crop cultivation required forHanwoo certification in Korea, with forage crop sufficiency index of 49.6%. The forage self sufficiency index of grazing eco-farmswas 108.5%, and self-certified (PGS) and conventional livestock farms was only 24.5 and 25.6%, respectively. The forage selfsufficiency index was 60.4, 52.9, and 111.9% for Hanwoo + grassland crop, Hanwoo + forage crop + rice, and Hanwoo + grasslandcombined farms, respectively. Livestock density was 10.3 LSU (livestock units)/ha for organic Korean cattle farms, which was lowerthan 25.6 LSU/ha for conventional farms. In addition, the livestock density of grassland eco-farms was the lowest at 3.4 LSU/ha.Livestock density was 12.2 LSU/ha in the southern region, which was lower than in the central-northern region. In conclusion, foragecrop sufficiency and livestock density are considered valid indicators for assessing the level of crop-livestock integrated agriculture.
