초록

본 연구에서는 단백질(51~5%) 및 지질(9~15%) 함량이 다른 배합사료(EP)와 생사료(MP)를 공급하면서 사육한 양식넙치의 육질을 비교해 보고자 하였다. 사육실험은평균체 중 106g의 넙치를 원형수조에 40마리씩 실험구별로 2반복으로 수용하면서, 단백질 및 지질 함량이 서로 다른 실험 배합사료(EP1, EP2, EP3)와 수입산 상품 배합사료(EP4) 및 MP를 16주간 공급하면서 사육하였다. 수분함량은 생사료(MP)를 공급한 넙치의 등근육에서 배합사료(EP)를 공급한 넙치의 등근육보다 유의적으로 높은 값을 나타내었다. 16:1n-7, 20:4n-6 및 20:5n-3의 함량은, 수입산 배합사료 EP4 및 MP를 공급한 넙치의 등근육에서 실험배합사료 EP1, EP2, EP3을 공급한 넙치 등근육보다 높게 나타났으나, 18:2n-6의 함량은 EP4 및 MP 공급구가 낮게 나타났다. 22:6n-3의 함량은 모든 실험구에서 높게 나타났으나 유의적인 차이를 보이지는 않았다. Taurine 함량은 MP를 공급한 넙치의 등근육에서 EP를 공합한 모든 넙치의 등근육보다 유의적으로 가장 높은 값을 나타내었다. Asparagine의 함량은 실험배합사료 EP1을 공급한 넙치의 등근육에서 EP2, E3, EP4 및 MP를 공급한 넙치 등근육보다 유의적으로 높은 값을 나타내었다. 각 사료를 공급한 넙치 등근육의 유리아미노산 중 lysine 및 serine의 함량도 유의적인 차이를 보였다. 핵산관련물질 중 넙치 등근육의 IMP 함량은 공급한 각 사료의 영향을 받아 유의적인 차이를 보였다. 물성측정 결과는 공급한 사료에 따라 큰 차이를 보이지 않았다.

This study was conducted to investigate the effect of extruded pellets (EP) containing different levels of protein (51%-55%) and lipid (9%-15%) on flesh quality of flounder (Paralichthys olivaceus) comparing with raw fish-based moist pellet (MP). Two replicate groups of 40 fish per each tank (initial mean weight 106 g) were fed one of three experimental EP (EP1, EP2 and EP3) containing different protein and lipid levels, a commercial EP (EP4) and MP for 16 weeks. Moisture content of fish fed MP was significantly higher than that of fish fed all EP. Significantly higher contents of 16:1n-7, 20:4n-6, 20:5n-3 and lower 18:2n-6 were observed in fish fed EP4 and MP compared with fish fed EP1, EP2, EP3. The 22:6n-3 content was not significantly different among all groups. Taurine content of fish fed MP was significantly higher than that of fish fed all EP. Asparagine content of fish fed EP1 was significantly higher than that of fish fed EP2, EP, EP4 and MP. Significant difference were observed in lysine and serine contents of fish fed experimental diets. In nucleotides and their related compounds, ATP and AMP content was not affected by diets. Significant difference were observed in IMP contents of fish fed experimental diets. Textural properties, no significant difference was observed among the fish groups fed different diets.
