Efficacy of Dietary Probiotic Supplementation with Inclusion of Q Z Toss™ on Nile Tilapia

The current study was designed to investigate the probiotic potential of the Biogen with and without the water quality improvement product Q Z Toss™ on growth and health performance of Nile tilapia (Oreochromis niloticus). Four fish groups were maintained on control diet supplemented with the biogen for one month. Both Biogen dietary levels exhibited significant increase in growth parameters as well as in white blood cell count with no negative impacts on renal functions. The histopathological examination revealed better renal epithelial status in Biogen treated groups than other groups, while gills showed significant improvement due to Q Z Toss™ treatment more than other untreated groups. Gills of all treated fish showed milder degrees of pathology in Q Z Toss™ treated groups represented by moderate hyperplasia in malpegian cell layers. Therefore, we can recommend the dietary inclusion of Biogen in aqua-feed along with Q Z Toss™ application in rearing water as an efficient method to achieve feasible and sustainable fish production.
