ABSTRACT The objective of the present study was to evaluate the effects of in ovo infusion of probiotic strains (Bacillus subtilis, Enterococcus faecium, and Pediococcus acidilactici ) on jejunal microbial population and mucin gene expression in broiler chicken. In a completely randomized design, 0.5 ml of mediums containing 107 cfu of different probiotic strains, was administered into amniotic fluid of the 480 Cobb fetus (day 18 of incubation), with four treatments, five replicates with twenty four eggs each. For mucin gene expression, samples from the jejunum were taken on day 21 of incubation and day 3 post-hatch. Microbial profile was determined for total lactobacillus and E. coli by sampling jejunal contents on days 1 and 3 of age. Expression of the...
