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

Abstract

The current study was designed to investigate the probiotic potential of the brewer’s yeast (Saccharomyces cerevisiae) 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 the control diet supplemented with the yeast for one month. Both yeast dietary levels exhibited a significant increase in growth parameters as well as in white blood cell count with no negative impacts on both hepatic and renal functions. The histopathological examination revealed better intestinal epithelial status in yeast treated groups than other groups, while gills showed significant improvement due to Q Z Toss™ treatment more than other untreated groups. Therefore, we can recommend the dietary inclusion of yeast in aqua-feed along with Q Z Toss™ application in rearing water as an efficient method to achieve feasible and sustainable fish production.raising growth and health performance of Nile tilapia (Oreochromis niloticus).
