초록

본 연구의 주목적은 돼지고기의 콜레스테롤 함량 감소에 관한 사료 내 ${\beta}CD$의 급여 효과를 조사하는 것이었다. 생체중 50 kg의 3원교잡종 거세 수퇘지 12마리를 이용하여서 4처리구 3반복으로 완전임의배치한 후, 시판체중인 110 kg 도달시까지 약 9주 동안 실험사료를 급여하였다. 일일 사료섭취량, 일일 증체량 및 사료효율은 ${\beta}CD$를 첨가하지 않은 대조구와 비교할 때, ${\beta}CD$ 1.5%, 3.0% 및 5.0% 첨가구의 각 처리구간 통계적인 유의차가 나타나지 않았다. 혈액 총지질, 중성지방 및 총콜레스테롤 함량은 대조구와 비교할 때 ${\beta}CD$ 첨가구가 유의적으로 낮아졌으며, 특히 ${\beta}CD$ 5.0% 첨가구에서 각각의 감소율은 21.80%, 55.58% 및 27.69%로서 가장 높게 나타났다(p<0.05). 돼지고기 삼겹살의 콜레스테롤 함량은 대조구와 비교할 때 ${\beta}CD$ 1.5%, 3.0% 및 5.0% 첨가구에서 각각 5.33mg, 12.70mg및 15.23 mg의 유의적인 감소를 나타났으며, 특히 이 값을 콜레스테롤의 감소율로서 나타냈을 때 각각 6.44%, 15.36%, 18.42%로서 유의적인 차이를 나타냈다(p<0.05). 이 결과는 돼지에서 ${\beta}CD$첨가급여가 콜레스테롤 대사를 조절할 수 있는 식이섬유로서 사용될 수 있음을 시사해준다.

The main objective of the present study was to determine the effect of dietary ${\beta}-cyclodextrin\;({\beta}CD)$ on reducing the cholesterol content of pork. Twelve swine of 50 kg body weight were randomly distributed into four groups of three heads each and fed experimental diets for 9 weeks until they reached a market weight of 110 kg. They were assigned to the four experimental diets containing 0% (control), 1.5%, 3.0% or 5.0% pure ${\beta}CD$. Daily feed intake, body weight gain and feed efficiency were not significantly different between any of the four group. The plasma total lipid, triacylglycerol and total cholesterol content of the swine in the three ${\beta}CD$-fed groups were significantly (p<0.05) decreased when compared to those in the control group, and were significantly (p<0.05) reduced by 21.80%,55.58% and 27.69%, respectively, in the swine fed on 5% ${\beta}CD$. The cholesterol content of pork belly (mg/100g) was significantly (p<0.05) decreased by 5.33 mg, 12.70 mg and 15.23 mg in the swine maintained on 1.5%, 3.0% and 5.0% ${\beta}CD$, respectively. The cholesterol content of pork belly, when expressed as the rate of reduced cholesterol, was significantly (p<0.05) decreased by 6.44%, 15.36% and 18.42% in groups of 1.5%, 3.0% and 5.0% ${\beta}CD$, respectively, when compared to that of the control group. These results suggest that dietary ${\beta}CD$ may be classified as dietary fiber which can modulate cholesterol metabolism in swine.
