Background: Using probiotics have become popular. They are considered an alternative to Antibiotic Growth Promoters (AGP). Probiotics are supplemented into animal feed for improving growth performance along with preventing and controlling enteric pathogens. The aim of this work was to study the impact of dietary supplementation of Mannan-oligosaccharide and β-Glucan (Agrimos®) on broiler challenged with Escherichia coli O 78 (E. coli O 78-marked with an antibiotic (320 μg ciprofloxacin/ml broth) on growth performance, serum biochemistry, immune organs-histopathology, E-coli colonization, and hepatic transcripts of Tumor necrosis factoralpha (TNF-α) and Nuclear factor-kappa B (NF-ϰB). A total of 125 one-day-old chicks were used for conducting the experiment. Five one-day-old chicks were slaughtered for measuring the initial weight of the lymphoid tissue. The remaining chicks (120) were allotted into four groups according to Mannan-oligosaccharide and β-Glucan supplementation, and E. coli infection. The data were analyzed using SPSS version 16. Results: Results indicated significant alteration of growth performance, serum biochemistry, and selected liver gene expression with pathological lesions, especially in the lymphoid organs due to E. coli infection. These alterations were mitigated by Mannan-oligosaccharide and β-Glucan supplementation. Conclusion: It could be concluded, Mannan-oligosaccharide and β-Glucan supplementation in broiler's diet improved the immune response of broilers and mitigated pathological lesion resulted from E. coli infection.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
