Lactic-acid bacteria are inhabitants of the digestive tract of chickens grown under commercial conditions. The sterile guts of hatched chickens become colonized by microorganisms on the very 1st days of life; normal microflora are completely developed by the end of the 1st wk. Lactic acid bacteria titers reach maximum values in warm seasons of the year. Streptococcus faecalis and S. faecalis var. liquefaciens dominate in the 1st days of life; S. faecium appears later. By 4-8 days, lactobacilli prevail in the gut, their amount reaching 109 cells/g of contents. Lactobacilli are mainly represented by Lactobacillus acidophilus, L. salivarius and L. fermentum.
