Effect of Dietary Supplementation of Biogen® (Commercial Probiotic) on Mono-Sex Nile tilapia Oreochromis niloticus under Different Stocking Densities

A.I. Mehrim

Abstract:
The present study was carried out to evaluate the effects of dietary supplementation of a commercial probiotic Biogen® on growth performance, carcass composition, blood hematological and biochemical parameters, histometric characteristics of fish dorsal muscles and economic efficiency of mono-sex Nile tilapia Oreochromis niloticus under different stocking densities. Therefore, fish with similar body weight (12.71±0.17 g) were distributed randomly into seven treatments at different stocking densities, being 10 fish m-3 which fed a basal diet without Biogen® (T1), 10 fish m-3 (T2), 20 fish m-3 (T3), 30 fish m-3 (T4), 40 fish m-3 (T5), 50 fish m-3 (T6) and 60 fish m-3 (T7), which were fed the basal diet but supplemented with 3 g Biogen® kg-1 diet for 14 weeks. The obtained results indicated that T4 was the best treatment which realized significantly (p≤0.05) increases of all growth performance parameters (final weight, AWG, ADG and SGR), hematological parameters (hemoglobin, RBCs count, PCV, blood platelets and WBCs count), plasma proteins (total protein, albumin, globulin and albumin/globulin ratio), improved FCR, blood indices (MCV, MCH and MCHC), differentiation of leukocytes, carcass composition, histometric characteristics of fish dorsal muscles and best economic efficiency. There were no adverse effects on water quality criteria among all experimental treatments. Consequently, from the obtained results, it could be concluded that the inclusion of the commercial probiotic Biogen® at a level of 3 g kg-1 diet at stocking density rate of 30 fish m-3 of mono-sex Nile tilapia O. niloticus is useful to get the best fish performance with friendly effects on the environment.
