中文摘要

The percent weight gain (PWG) and feed efficiency (FE) of Epinephelus coioides were calculated, and the lactobacilli and total microbiota in the posterior intestines, and non-specific immune parameters of grouper, and its susceptibility to Streptococcus sp. and an iridovirus were determined when the fish were fed diets containing Lactobacillus plantarum at 0 (control), 106, 108, or 1010 colony-forming units (cfu) kg?1 for 4 weeks. Results showed that grouper fed a diet containing L. plantarum at the levels of 106, 108, and 1010 cfu kg?1 had significantly increased PGW and FE especially at 108 cfu kg?1 group which were 404.6% and 1.26, respectively. L. plantarum significantly increased in the fish posterior intestines during the L. plantarum feeding period, but decreased rapidly from the intestine within 1 week after changing to the control diet (without L. plantarum). Fish fed a diet containing L. plantarum at 106 and 108 cfu kg?1 had significantly higher survival rates than those fed the control diet after challenge with Streptococcus sp., as well as those fed 108 cfu kg?1 after challenge with an iridovirus, causing increases in the survival rates of 23.3%, 20.0%, and 36.7%, respectively, compared to the control group. The alternative complement activity (ACH50) level of fish fed diets containing L. plantarum after 4 weeks was significantly higher than that of fish fed the control diet, and that of the 108 cfu kg?1 group was significantly higher than those of the 106 and 1010 cfu kg?1 groups, which increased by 83.4% compared to the control group. The lysozyme activity and glutathione peroxidase (GPx) activity of fish fed the L. plantarum-containing diets at 108 and 1010 cfu kg?1 significantly increased compared to those fed the 106 cfu kg?1L. plantarum diet and control diet, and had increased by 76.3% and 136.6%, and 57.1% and 113.3%, respectively, compared to those fed the control diet. The phagocytic activity (PA), phagocytic index (PI), and respiratory bursts of head kidney leucocytes of fish fed 106, 108, and 1010 cfu kg?1L. plantarum diets were significantly higher than those of fish fed the control diet after 4 weeks of feeding, and increased 2.2-, 2.2-, and 2.3-fold; 1.8-, 1.8-, and 2.0-fold; and 1.4-, 1.4-, and 1.4-fold, respectively, compared to the control group. We therefore recommend dietary L. plantarum administration at 108 cfu kg?1 to promote growth and enhance immunity and resistance against Streptococcus sp. and an iridovirus of E. coioides.
