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

Abstract

The current study was designed to investigate the potential of bioorgano (thymol and carvacrol) with and without the water quality improvement product Q Z Toss™ on growth and health performance of Nile tilapia (Oreochromis niloticus). Six fish groups were maintained on control diet supplemented with the bioorgano for one month. Both bioorgano dietary levels exhibited 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 bioorgano treated groups than other groups, and an increase in intestinal villi length regardless of bioorgano concentration used. while the posterior kidney showed activation of melanomacrophages centers (MMCs) which is linked to enhancement of fish immune response. Therefore, we can recommend the dietary inclusion of bioorgano in aqua-feed along with Q Z Toss™ application in rearing water as an efficient method to achieve feasible and sustainable fish production.
