Abstract

The purpose of this study was to investigate the carcass characteristics and the primal cut yields from carcasses according to the sex of Hanwoo. Experimental animals comprised of 80 cows, 29 bulls, and 71 steers. After slaughtering, they were evaluated to estimate the productivity of carcass components by market weight, and to predict the beef carcass yield. The average of fasting weight of cow, bull and steer were 634.75 kg, 721.86 kg, and 754.10 kg respectively. Market weight of Hanwoo at cold carcass weight, primal lean cut weight, sub-primal lean cut weight, bone weight and fat weight were 381.01~467.60 kg, 240.79~310.36 kg, 208.27~276.47 kg, 57.23~76.28 kg and 89.19~138.97 kg respectively. Body measurement traits had side length, hindquarter length, cervical vertebrae length, lumbar vertebrae length, sacral vertebrae length, 6th lumbar vertebrae~heel length, 5~6th thoracic vertebrae breadth, 4~5th lumbar vertebrae breadth, 5th sacral vertebrae breadth, 7~8th thoracic vertebrae girth and 7~8th thoracic vertebrae thick were highest length in steer. Carcass weight (CW) were significantly (p<0.05) affected by sex and live weight. The lean meat percentage, fat percentage and bone percentage based on the weight of cold carcasses were significantly different (p<0.05) between sex groups. The primal cuts rate for deungsim, moksim, abdari, udun, suldo, yangjee and satae were higher in bulls than those of the caws and steers. The carcass by-product weight rate in steer had lower oxtail and rib cartilage than cow and bull, while cow showed lower beef leg bones and jappyeo than bull steer (p<0.05). Body measurement traits was always important for primal cut weight estimates.

본 연구는 한우의 성별에 따른 도체 특성 및 부분육 생산량을 조사하여 도체로부터 고기의 생산수율을 조사하고자 실시하였다. 한우 180두(암소 80두, 수소 29두 및 거세우 71두)를 도축한 다음 가공단계 별 중량변화, 도체규격, 대분할 부위 생산량 및 수율, 소분할 부위 생산량 및 수율, 부산물 생산량 및 수율을 조사하였다. 한우의 절식체중은 안소 634 kg, 수소 721 kg, 거세우 754 kg이었으며, 가공단계 별 중량변화는 냉도체중 381.01~467.60 kg, 대분할육 240.79~310.36 kg, 소분할육 208.27~276.47 kg, 뼈 57.23~76.28 kg, 지방 89.19~138.97 kg을 나타내었다. 한우 도체규격은 거세우에서 전장, 후 사분체장, 경장, 요장, 선장, 퇴장, 흉폭, 요폭, 퇴폭, 흉위 및 흉후가 가장 길었다(p<0.05). 도체중량은 생체중의 성별에 영향을 받았으며, 정육율, 지방율 및 뼈수율은 성별에 따라 영향을 받았다. 대분할 정육율은 수소가 등심, 목심, 앞다리, 우둔, 설도, 양지, 사태에서 유의적으로 높은 수율을 나타내었다(p<0.05). 도체부산물 수율에서 거세우는 가장 낮은 꼬리반골 및 갈비뼈 생산 수율을 나타내었고(p<0.05), 암소의 사골 및 잡뼈 생산수율이 가장 낮았다(p<0.05). 도체규격과 부분육 생산수율 조사는 도체특성에 따라 부분육 생산량을 예측할 수 있는 자료로 활용할 수 있을 것으로 사료된다.
