Abstract:

Antibiotics have been used in poultry industry for decades to promote growth and protect animals from diseases, followed by various side effects. In efforts of searching for a better alternative, prebiotic is of extensive attention. The EPS-based prebiotics that may be used for chicken might been suggested as an effective strategy to decrease infection in chicken. It is only in the last few years that LAB EPS have taken attention with regard to prebiotic potential. For this reason, in experiment 1, 119 bacteria of lactobacilli isolated from the gastrointestinal tract of 24 chicken. For experiment 2, the isolates were tested for their exopolysaccharides production levels. In these isolates, exopolysaccharides production were assessed varies from 43-443 mg/L. In experiment 3, for molecular identification, 11 isolates that produced high EPS were selected. These lactobacilli isolates were acknowledged using 16S rRNA sequence analysis. As a result of the identification, isolates were identified as Lactobacillus salivarius (6 strains), L. reuteri (2 strains), L. aqilis (2 strains) and L. saerimneri (1 strain). These bacteria EPSs may be good alternatives to antibiotics in promoting growth resulting from a beneficial modulation of the intestinal microbiota, which leads to increased efficiency of intestinal digestion in the host animal.
