Comparative effects of using a single strain probiotic and multi-strain probiotic on the productive performance and disease resistance in Oreochromis niloticus.
The study was carried out to evaluate the effect of dietary supplementation of three probiotic strains in isolation and a multi-strain formulation (mix) on the rearing of tilapia, based on the parameters of productive performance and resistance to infection. A total of 240 juveniles of Oreochromis niloticus (6.71 ± 0.93 g and 61.88 ± 1.44 mm) were fed for 90 days with fish food containing two varieties of Enterococcus faecium and one variety of Bacillus cereus following therapeutic concentrations reported in the literature, and one multi-strain formulation containing the three organisms. After the period of food supplementation, 45 specimens were injected intraperi-toneally with 300 μL of Streptococcus agalactiae at a lethal concentration of 1.7 × 107 CFU.g.
