Effect of pediococcus acidilactici and saccharomyces boulardii as probiotics on intestinal and caecal colonization of salmonella typhimurium and clostridium perfringens in broiler chickens

ABSTRACT

A significant reduction in intestinal and caecal colonization of Clostridium perfringens [C. perfringens] during 21 days post infection [PI] has occurred on using the probiotics Pediococcus acidilactici or Saccharomyces boiilardii. However; the former resulted in a higher reduction than the latter. The same results were also obtained with Saccharomyces boulardii at 7 and 14 days PI. Reduction in Salmonella typhimurium [S. typhinwrium] caecal colonization significantly happened during the entire period of the experiment [21 days] on using the two studied probiotics. Neither mortality nor disease lesions could be obtained in experimentally infected groups with the used doses of both S.typhimurium and C perfringens under the conditions of the experiment
