Abstract

Growth, feed efficiency and condition factor of the olive flounder fed supplemented diets containing different levels of Obosan were significantly (P<0.05), especialluy at the optimum level of 0.6% Obosan. The hematological values (RBC count, hemoglobin, hematocrit, MCHC, MCV and MCH) were not significantly different among the flounder fed diets containing different levels of Obosan (P> 0.05). However, serum concentrations of total protein and glucose in the flounder, feds Obosan supplemented diets, were significantly higher, while the levels of total cholesterol, COT and GPT were lower than those of control fish (P<0.05)i the values for COT and GPT were only about half that of the control (P<0.05).

시판되는 넙치용 부상사료에 한방사료 첨가제인 어보산을 농도별 (0, 0.6및 1.2%)로 첨가한 후, 넙치의 성장, 사료효율, 비만도 및 혈액성분에 미치는 효과를 비교한 결과, 체중의 성장은 실험 8주 후부터 대조군과 첨가군간에서 유의한 차이가 나기 시작하여, 실험종료시 첨가군들이 대조군에 비해 7.8~9.1% 더 증가하였다 (P<0.05). 실험 전 기간을 통해 어보산 첨가군들의 일일성장률은 대조군보다 5.9~7.1% 더 좋은 결과를 보였고, 첨가군들의 사료효율도 대조군보다 13.2-14.2% 더 향상됨을 보였으며, 실험종료시 비만도도 첨가군들이 대조군에 비해 3.2~3.5% 정도의 유의한 증가를 보였다 (P<0.05). 특히 어보산 첨가군들 간의 성장 결과에서는 서로 유의한 차이가 나지 않음으로써, 어보산의 넙치 부상사료에 대한 적정 첨가농도는 0.6%로 판명되었다. 어보산 첨가농도별 넙치용 부상 사료로 사육한 넙치의 혈액성상을 분석한 결과, 각 실험군간 유의적 인 차이가 관찰되지 않았으나 (P>0.05), 혈청성분은 대조군과 어보산 첨가군들간 뚜렷한 차이를 보였는데, 어보산 첨가군들이 대조군에 비해 total protein과 glucose에서 높았고, total cholesterol, GOT와 GPT에서 낮은 값을 보였다 (P<0.05). 특히 혈청 GOT와 GPT에 있어 어보산 첨가군들은 대조군에 비해 매우 낮은 값을 보였다(P<0.05).
