中文摘要

Probiotics have widely applied as a dietary supplement in aquaculture. The objectives of this study were to elucidate the effects of dietary administration of Lactobacillus plantarum 7-40-supplemented diets at 103, 105, 107 cfu g-1 to Epinephelus coioides on (1) growth performances, (2) innate immune responses. In the growth performance test, the feed conversion ratio of fish fed 103, 105, and 107 cfu g-1 L. plantarum-supplemented diets were significantly higher than that of fish fed the control diet for 4 weeks. The mean body weight, relative gain weight, daily gain weight, specific growth rate of fish fed 105 and 107 cfu g-1 L. plantarum-supplemented diets were significantly higher than that of fish fed control diet after 4 weeks of feeding. In the innate immune responses, leucocytes and serum of fish fed control and L. plantarum-supplemented diets for 2 and 4 weeks were used for evaluating the immune response parameters, The results showed that phagocytic activity and phagocytic index, respiratory burst activity, glutathione peroxidase, lysozyme and alternative complement activity of fish fed L. plantarum-supplemented diets at 105 cfu g-1and 107 cfu g-1 were significantly higher than those of fish fed the control diets for 4 weeks. However, the superoxide dismutase of fish fed L. plantarum-supplemented diets was significantly lower than that of fish fed with control diet after 2 and 4 weeks of feeding. It was concluded that L. plantarum 7-40 viability could promote the growth performance and enhance innate immune responses.
