Studies were conducted on the effect the addition of a probiotic preparation containing Carnobacterium divergens or Enterococcus hirae bacteria isolated from the alimentary tract of common carp, Cyprinus carpio L. had on the growth and food conversion ratio in the rearing of two-year-old carp. The use of feeds with the addition of probiotic bacteria did not have any significant effect on the specific growth rate (SGR), food conversion ratio (FCR), or protein efficiency ratio (PER). The type of feed had no impact on the protein level in the fish bodies but the water content decreased. The highest changes were observed in the content of fat and mineral components in the fish bodies. The experimental results did not confirm any production advantages when Carnobacterium divergens or Enterococcus hirae bacteria were added to carp feeds
