배합사료에 크릴, 켈프, 마늘 또는 감귤 분말 첨가가 넙치 육성어의 성장, 혈액 성상 및 지방산 조성에 미치는 영향 = Growth Performance, Hematological Parameter and Fatty Acid Composition of Growing Olive Flounder (Paralichthys olivaceus) to Dietary Inclusion of Kelp Meal, Krill Meal, Garlic Powder or Citrus Meal

다국어 초록 (Multilingual Abstract)

This feeding experiment was conducted to investigate the effects of dietary inclusion of some additives on growth performance, hematological parameter and fatty acid composition of growing flounder. Triplicate groups of fish (average weight 120 g) were fed one of five diets containing 5% kelp meal (Ke), 10% krill meal (Kr), 1% garlic powder (Ga), 1% citrus meal (Ci) or control diet (Con) without supplementation for 15 weeks. After the feeding experiment, survival was not significantly different among the groups fed the different diets. Weight gain of fish fed the Ci diet was significantly higher than that of fish fed the Kr diet, but not significantly different from Con, Ke and Ga treatments. Feed efficiency and protein efficiency ratio of fish fed the Ga diet were significantly higher than those of fish fed the other diets. Total protein, glucose, GOT, GPT and total cholesterol contents in the plasma were not affected by the dietary additives. Composition of C20:4n-6 in the dorsal muscle of fish fed the Con diet was significantly higher than that of fish fed the other diets. The results of this study suggest that the dietary inclusion of garlic meal at 1% may improve feed utilization of growing flounder.
