碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 95 / The prupose of this study use the HBSS extract of Bidens pilosa、Lonicera japonica and Cyathula officinalis to culture the leukocyte of Cobia (Rachycentron canadum) and oral administered various doses to know the effect on growth, and non-specific immune response of cobia. Therefore, the growth performance and non-specific immune parameters such as weighe gain (WG), feed conversion ratio (FCR), superoxide anion (O2-), superoxide dismutase activity (SOD), phagocytic rate, phagocytic indexs, lysozyme activity, albumin, globulin and albumin / globulin ratio (A/G ratio). The result in experiment 1 showed that the leukocyte of cobia with various doses of B. pilosa, L. japonica and C. officinalis HBSS extract had significantly (P < 0.05) enhanced on superoxide anion (O2-) production capacity, and 100mg/ml than others. After 10 weeks, the result in experiment 2 showed fed diets with B. pilosa and C. officinalis were significantly (P < 0.05) enhanced the superoxide anion production, superoxide dismutase activity, lysozyme activity, phagocytosis rate and phagocytosis index in low treatment. The result in experiment 3 showed the superoxide anion production, superoxide dismutase activity, lysozyme activity, phagocytosis rate and phagocytosis index and albumin level were significantly (P < 0.05) enhanced in cobias fed the with diets containing B. pilosa and C. officinalis during 32 days. The result also showed that the cobias fed diets with 30 g/k , 50 g/kg B. pilosa and C. officinalis be able to increased growth and non-specific immune response.
