Cím:	Effect of selected feed additives on growth performance and the intestinal microbiota of the Common carp (Cyprinus carpio) / Elshafia Ali Hamid Mohammed, Milán Fehér, Péter Bársony, Abdelhakam Esmaeil Mohamed Ahmed, Ayaz Mukarram Shaikh, Károly Pál

Megjegyzések:	The research aimed to examine the impact of various feed additives on the growth performance and intestinal microbiota of the common carp (Cyprinus carpio). Three different feed additives including Bactocell (live lactic acid bacterium Pediococcus acidilactici CNCM I-4622 MA 18/5M), Levucell (probiotic derived from the fungus Saccharomyces cerevisiae boulardii CNCM I-1079) and YANG prebiotic (Saccharomyces cerevisiae AQP1260, S. cerevisiae AQP 12988 and Cyberlindnera jandinii AQP 12549) were tested at the concentration of 1% (10 g/1 kg of basic diets) in addition to the control (basic feed only). Fish with average body weight (g) of 932?163 were fed with supplemented diet for 45 days in a recirculation system (RAS). The RAS contains 12 units (size=1000 liter each unit, 8 fish per unit). Water temperature, pH, total dissolved solids, dissolved oxygen, NO-2 , NO-3 , and NH+4 concentrations were maintained within optimal levels. After the end of the feeding experiment, fish feces samples were collected and the bacterial community structure found in the intestines of common carp was analyzed through a metagenomic approach using 16S rDNA sequencing. The results indicated that there was no significant effect (P<0.05) of the tested feed additives (Bactocell, Levucell and YANG) on growth performance (final body weight), feed conversion ratio (FCR) and specific growth rate (SGR). The results of the metagenomic data of carp fed with a diet supplemented with YANG showed 11 different groups of bacterial phyla detected with the top three phyla, namely Fusobacteria (55%), Firmicutes (36%), and Proteobacteria (6%). In contrast, fecal samples from carp fed with 1% Bactocell recorded 10 phyla. The top three phyla were Proteobacteria (70%), Fusobacteria (21%), and Firmicutes (5%). A sample of carp fed with Levucell recorded 9 phyla, the top three phyla were Fusobacteria (50%), Proteobacteria (35%), and Firmicutes (14%). Finally, samples from carp fed with the basal diet (the control) recorded 14 phyla. The top three phyla recorded were Fusobacteriota (68%), Proteobacteria (27%), and Bacteroidota (3%). The study found that the tested feed additives did not significantly affect the growth performance of common carp. However, they did lead to variations in the composition of the intestinal microbiota of the common carp.
