Influence of probiotic (Streptococcus faecium M74) on weight gain (g/ind), feed conversion ratio (FCR), specific growth rate (SGR) and content of intestinal microflora in carp fry was investigated. The experimental group had higher average individual weight by 12.42%, better feed conversion by 17.37% and higher specific growth rate by 10.20% after 6 growth weeks. Carp intestinal microflora in both control and experimental groups had autochthonic microorganisms (Escherichia coli, Enterobacteriaceae, Streptococcus faecalis, Staphylococcus aureus, Bacillus sp., Clostridium sp.). Representation of Enterobacteriaceae, Streptococcuss faecalis, Staphylococcus aureus in relation to the control group was considerably reduced in the experimental group whereas Escherichia coli was completely eliminated after 14 days of probiotic feeding .
