Effects of digestive tract probiotics on immune enzyme activity and anti-WSSV ability of Litopenaeus vannamei
摘要
Abstract
A 20 days feeding experiment was conducted to study the effects of probiotics on immune enzyme activity (alkaline phosphatase AKP,a cidic phosphatase ACP, superoxide dismutase SOD,catalase CAT and lysozyme UL) and anti-WSSV ability of Litopenaeus vannamei. Diets were supplemented with Photobacterium damsela(live,≥1011 CFU/g or inactivated, 1 g/kg)or Bacillus firmus{ live,≥1011 CFU/g or inactivated, 1 g/kg). Controls were fed non-supplemented diet. In this experiment, feeding the bacteria species(inactivated P. Damsela;live Bacillus firmus) significantly increased serum ACP,AKP,SOD and CAT compared with controls ( P < 0. 05), at the same time, their cumulative morality were (49% ± 15% ) and (53% ± 12% ) respectively, which were significantly increased compared with controls (P <0.05). The present results suggested that the diets supplemented with B. Firmus (live) or P. Damsela (inactivated) could improve immune enzyme activity and anti-WSSV ability of shrimp, and the probiotics with the function of preventing disease could be used as one of effective ways of biological prevention and control to WSSV.关键词
