碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 94 / The purpose of this study is aimed to know the effect of Asiatic plantain, Houttuynia cordata and Mentha haplocalyx on the growth and non-specific immune response of cobia (Rachycentron canadum) by oral administration. Therefore, the growth performance and non-specific immune parameters such as weight gain (WG), feed conversion ratio (FCR), superoxide anion (O2-) production ratio, chemiluminescent response, superoxide dismutase activity (SOD), phagocytic rate, phagocytic indexes, lysozyme activity, albumin, globulin and albumin / globulin ratio (A/Gratio). The result in experiment 1 showed that the growth was not significantly affected by the dietary treatments but the superoxide anion, superoxide dismutase activity and phagocytosis were significantly (P＜0.05) enhanced in cobias fed diets with A. plantain and H. cordata after 6 weeks. Therefore, it is demonstrated that A. plantain and H. cordata are useful immunostimulants. The result in experiment 2 showed that the superoxide anion, superoxide dismutase activity, phagocytosis, chemiluminescent response and lysozyme activity were significantly (P＜0.05) enhanced in cobias fed the with diets containing A. plantain and H. cordata during 32 days. The albumin/globulin ratio gradually decreased in the serum after cobias fed the experimental diets containing A. plantain、H. cordata and M. haplocalyx along respectively. The result also showed that the cobias fed diets with A. plantain and H. cordata had higher non-specific immune response. And the cobias fed the with diets containing 1.0 % , 2.0 % A. plantain or H. cordata were significantly enhanced non-specific immune parameters from 4 to 24 days.
