초록

이유자돈 시기 25∼70일령까지 글루코사민 유도체를 1일 1두당 3 mL급여한 돼지와 급여하지 않은 돼지의 도체등급 특성과 육질특성을 비교한 결과는 다음과 같다. 도체중과 등지방층 두께는 시험구와 대조구간 유의적인 차이를 보이지 않았으나, 시험구가 표준오차가 적어 균일도가 높은 것으로 조사되었다. 도체등급 판정결과 최종 A등급 출현율을 비교했을 경우에는 시험구 및 대조구에서 각각 48.7%, 29.2%로 시험구가 약 19.5% 높은 출현율을 보였다. 돼지고기의 육질을 비교한 결과 육색, 가열감량, 전단력, pH 보수성, 육즙분리율 등 대부분의 육질에서 유의적인 차이를 보이지 않았으나(p>0.05), 일반성분중 단백질과 회분은 시험구가 유의적으로 높은 경향을 보였다. 본 시험결과 이유후 육성돈 시기에 글루코사민 유도체의 급여는 육질에는 큰 차이가 없으나, 출하일령 단축과 도체등 급에서의 규격돈 생산에는 효과가 있는 것으로 나타났다.

The feeding group, composed of weaning pigs fed 3 mL of glucosamine derivatives, was compared for the carcass and quality characteristics with the unfeeding control group for 25∼70 days since they were born. The results were as follows; There were no significant differences in carcass weight and back-fat thickness between the feeding group and the unfeeding group although the feeding group had low ranges of standard error when compared to the control. Feeding group had higher incidence frequencies of A grade (42.7%) than the control (29.2%). The feeding group and unfeeding group had no significant differences in meat color, cooking loss, WBS, pH, WHC and purge loss. Results from this study showed that feeding GD had effect on the decrease the market weight and production of consist carcass weight, however, the feeding GD had no effect on pork quality during rearing times after weaning.
