Probiotics are defined as non-pathogenic, living natural intestinal microorganisms that produce beneficial effects on intestinal microflora, which have antagonistic action against pathogens in the intestines of the administered organisms. The first study on probiotics was conducted by Elie Metchnikoff in the late 19th century and reported the lactic acid bacteria isolated in fermented milks as a probiotic. The most common lactic acid bacteria used as probiotics are Lactobacillus, Streptococcus, Enterococcus, Leuconostoc, Pediococcus and Bifidobacterium. Probiotic bacteria shouldn’t be pathogenic for animals, toxin-producing and transferable antibiotic resistance gene carrier should be able to hold onto the intestinal cells, colonize and metabolize unaffected from low pH and bile salts and able to survive during production and storage. The increase in live weight, improvement of utilization of feed and decrease of gastrointestinal diseases are reported after probiotic administration in animals. The current knowledge about commercial probiotic products shows that they are reliable. Nevertheless, the selection of potential probiotic bacteria requires the compulsory safety criteria recommended by the European Union. As a result; although probiotics are not considered to take antibiotics in the treatment of an acute illness, they can be used as an alternative to antibiotics in protective treatment and encouraged to grow in animals. Their use will become more widespread in the future and maximum efficiency will be obtained from animals under different conditions.
