Abstract
- The goal of the current study was to determine how probiotic bacteria (Latiplantibacillus plantarumand Bacillus toyonensis) as water additives affected growth performance, immune response, antioxidant indices, water quality and intestinal bacterial counts of Nile tilapia. A total of 120 monosex fingerlings of Nile tilapia (mean weight of 17.4 ± 0.1 g) after two weeks of acclimatization were divided into four groups, each with 30 fish (3 replicates). The first group served as a control (T1), whereas the second, third and fourth groups were exposed to B. toyonensis(T2), L. plantarum(T3) and L. plantarumand B. toyonensis(T4) at doses of 1.0 ml/L water. L. plantarumand B. toyonensiscultures significantly affected the growth performance, immune responses, antioxidative status, and intestinal bacterial counts of Nile tilapia. Latiplantibacillus plantarum-exposed fish showed the best values of feed intake (FI) and feed conversion ratio during the overall experiment. Total coliform, Escherichia coliand Salmonellaspp. (TC) were decreased (P<0.001) by probiotic-treated water. Latiplantibacillusand/or Bacillusenhanced growth performance and diminished microorganisms' proliferation in the water and fish intestine. Supplementing the water with probiotic reduced triglyceride, low density lipoprotein (LDL), and very low density lipoprotein (VLDL), and improved immune indices (IgG, IgM, IgA, and lysozyme). Finally, adding the probiotics to water may improve the performance, antioxidant indices, immunity, and intestinal pathogen mitigation.
