Abstract
The effects of the Bacillus probiotics powder, Bacillus subtilis 7 x 106 cfu g-1 and Bacillus cereus 2.5 x 107 cfu g-1 via dietary additional to control vibriosis disease in white shrimp culture for 14 days were evaluated. The results indicated that good recovery in shrimp fed with probiotic (T4) and the mortality reduced (86.7%), in comparison with the group without probiotics and with pathogen, Vibrio spp. (T3). In addition, it presented lower counts of Vibrio spp. than group fed without the probiotic causing a significantly reduced pathogen. Bacillus probiotics, B. subtilis and B. cereus had a better effect on hematological shown in the total haemocyte counts (THC) of the group with probiotic and with pathogen, Vibrio spp. (T4) had the highest THC every day throughout the experiment experiment followed by the group with probiotic and without pathogen (T2) respectively. Therefore, B. subtilis and B. cereus significantly enhanced the shrimps' ability to recover from Vibrio spp. infections and enhanced the quality of their cultures.
