Abstract

This study was conducted to investigate the effects of different dietary dimethy-β -propiothetin (DMPT) levels on growth and body composition in Korean rockfish (Sebastes schlegeli) after a eight weeks feeding experiment. Body weight gain, feed efficiency and feed intake were significantly increased with dietary DMPT level. After eight weeks of feeding trial, moisture content decreased with supplemented DMPT level, while crude protein and lipid contents increased with dietary DMPT level. Amino acid content was elevated DMPT feeding groups compared to the control group. Amino acid composition was not significantly different in the dietary groups. Fatty acid content increased with dietary DMPT level.

수산물 중에 다량으로 분포하는 섭이촉진물질로 알려진 DMPT의 추출 이용을 위한 기초 자료를 얻 고자 DMPT를 3 mM, 5 mM, 10 mM로 첨가한 실험용 사료로 8 주간 사육한 조피볼락의 성장효과 및 어체 성분에 미치는 영향을 검토한 결과를 요약하면 다음과 같다. 1. DMPT를 첨가하지 않은 대조구의 체중증가율은 약 1.2 배였으나 10 mM을 첨가한 사료의 경우는 약 1.4배로 성장효과가 크게 증가하였고, 사료효율 및 사료 섭취량도 많아 DMPT가 사료 섭이를 촉진시키는 것으로 나타났다. 2. 일반성분 변화 를 보면 DMPT의 농도가 높을수록 수분 함량은 감소하고 조단백질과 조지방의 함량은 함께 증가하는 경향이었다. 3. 아미노산 함량의 변화에서는 대조구가 3286.3 mg%에 비하여 10 mM 첨가구에서는 3568.3 mg%로 높은 값을 나타내어 DMPT 첨가구가 높데 나타났으며, 구성아미노산 조성에 있어서는 서로 비슷한 경향이었다. 4. 지방산 함량의 변화를 살펴보면, 실험개시전과 대조구에 비하여 DMPT 첨 가구에서 높게 나타났으며, DMPT의 농도가 높을수록 지방산의 함량도 증가하여 지방의 함량 변화와 일치하였다.
