Abstract

The current study was conducted to compare the growth performance and physico-chemical characteristics of Hanwoo bulls and steers of different slaughtering ages. Thirty-six Hanwoo (average age, 13-mon) were allocated into either a bull or steer group (18 animals/group). Each group was sub-divided into 26-, 28-, and 30-mon-old age groups (six animals/group). Surgical castration was performed in the steer group immediately after the experimental groups were assigned. Growth performance of the animals, as well as carcass characteristics and fatty acid composition of M. longissimus dorsi were determined. Cold carcass weights increased as carcass slaughtering age increased in both Hanwoo bulls and steers (p<0.05). Backfat thickness was thickest (p<0.05) in 28-mon-old Hanwoo bulls and 30-mon-old steer, and the M. longissimus dorsi area was widest (p< 0.05) in 28-mon-old Hanwoo bulls and steers. Marbling score, cooking loss, and water holding capacity (WHC) were higher (p<0.05) in 30-mon-old Hanwoo bulls and steers as slaughtering age increased. The shear force value was highest in 30-mon-old Hanwoo bulls and 26-mon-old Hanwoo steers compared to that in other groups. The unsaturated fatty acid composition in M. longissimus dorsi was significantly (p<0.05) higher in 28- and 30-mon-old Hanwoo bulls and steers than that in other groups. The results suggest that castration, even at late stages of Hanwoo development, improved beef carcass quality grade, and that no difference in beef quality grade had occurred (marbling score and WHC) in 28- and 30-mon-old slaughtering age Hanwoo steers.

본 연구는 한우의 거세유무 및 도축월령에 따른 비육능력 및 도체의 이화학적 특성 비교를 구명하기 위하여 생후 13개월령의 비육한우 36두(비거세한우 18두 - 3처리 ${\times}$6두; 거세한우 18두 - 3처리 ${\times}$두)를 공시하여 생후 26개월, 28개월, 및 30개월령까지 비육한 후, 도체특성, 도체의 이화학적 특성 및 지방산 조성을 조사하였다. 도체의 냉도체중은 도축월령이 길어짐에 따라 비거세우와 거세우 모두 증가하였다(p<0.05). 등지방 두께에서 비거세우군은 28개월령이, 거세우군은 30개월령이 가장 두껍게 나타났고(p<0.05), 배최장근 단면적에서 비거세우군과 거세우군 모두 28개월령 때가 가장 넓게 나타났다(p<0.05). 근내지방도, 가열감량 및 보수력은 양 처리군 모두 30 개월령 도축할 때 가장 높았고(p<0.05), 비육기간이 길어질수록 높아지는 경향이었다. 전단력의 경우 비거세우군은 30개월령일 때에, 거세우군에서는 28개월령에 높았다. 도체의 불포화 지방산(unsaturated fatty acid, UFA)은 양 처리군에서 28개월령과 30개월령이 유의적으로 높았다(p<0.05). 이상의 연구결과를 종합해 볼 때, 한우의 장기비육에 있어서 늦게라도 거세를 실시하면 뚜렷한 도체등급의 개선 효과가 있으며, 거세비육우의 도축월령은 육질적측면(마블링 스코어와 보수력)에서 생후 28개월과 30개월령 간에는 거의 차이가 없었다.
