초록

본 시험은 고에너지 수준의 사료를 급여한 돼지의 사양성적, 돈육의 도체 특성, 일반성분, 이화학적 특성 및 지방산 조성에 미치는 영향을 조사하기 위해 실시하였다. 80$\pm$3 kg의 삼원교잡종 120두를 공시하여 비육돈 사료 변화의 영양소 수준에 따라 저에너지 DE 3,290 kcal/kg, CP 14.5%, Lysine 0.70%, Ca 0.78로 배합한 사료를 38일간 급여하였고, 고에너지 DE 3,350 kcal/kg, CP 15.0%, Lysine 0.10%, Ca 0.78%로 배합한 사료를 27일간 급여하였다. 저에너지와 고에너지 사료를 급여한 돼지의 종료체중이 101 kg내외에 도달했을 때 도축하여 시험에 공시하였다. 고에너지 사료를 급여한 돼지가 일당 증체량이 높았고, 사료섭취량과 사료요구율은 낮았다(p<0.05). 도체특성과 일반성분은 차이를 보이지 않았다 이화학적 특성 중 고에너지 사료를 급여한 돈육의 가열 감량과 황색도는 저에너지 사료를 급여한 돈육에 비해 현저히 높게 나타내었다(p<0.05). 지방산 조성에서는 저에너지와 고예너지 사료를 급여한 돈육에서 차이를 보이지 않았다. 이상에서 고에너지 사료를 27일간 급여한 돼지는 저에너지 사료를 38일간 급여한 돼지에 비해 성장률이 향상되었고, 돼지의 도체 특성, 물리적 특성 및 지방산 조성에는 미치지 않았지만 돈육의 가열 감량과 황색도가 높았다.

In a trial involving 120 pigs, the growth performance of finishing pigs and proximate composition, physicochemical properites and fatty acid composition of loin muscle were investigated by feeding the high-energy density diet and low-energy density diet. The treatments included feeding 1) the low-energy density diet (3,290 cal/kg DE, 14.50% CP, 0.70% lysine and 0.78% Ca) for 38 days and 2) the hight-energy density diet (3,350 cal/kg ME, 15.0% CP, 0.70% lysine and 0.78% Ca) for 27 days. The average daily gains were significantly higher for pigs fed the high-energy density diet than those fed the low-energy density diet, but average daily feed intake and feed conversion rate were significantly lower than those fed the low-energy density diet (p<0.05). The cooking loss and yellowness of pork were significantly (p<0.05) lower for pigs fed the low-energy density diet than those fed the high-energy density diet. There were no significant differences in carcass characteristics, proximate composition and fatty acid composition of pork. In conclusion, the results of the experiment suggested that the high-energy density diet for pigs tended to improve the growth performance, but the cooking loss and yellowness of pork were higher for pigs fed the high-energy density diet than those fed the low-energy density diet.
