There are well documented complications associated with the continuous use of antibiotics in the poultry industry. Over the past few decades, probiotics have emerged as viable alternatives to antibiotics; however, most of these candidate probiotic microorganisms have not been fully evaluated for their effectiveness as potential probiotics for poultry. Recent evaluation of a metagenome of broiler chickens in our laboratory revealed a prevalence of Lactobacillus reuteri (L. reuteri) and Actinobacteria class of bacteria in their gastrointestinal tract. In this study Lactobacillus reuteri and Streptomyces coelicolor (S. coelicolor) were selected as probiotic bacteria, encapsulated, and added into broiler feed at a …

The probiotic potential and antimicrobial activity of Lactiplantibacillus plantarum, Saccharomyces cerevisiae, and Bifidobacterium longum were investigated against Escherichia coli O157:H7, Salmonella typhimurium and Listeria monocytogenes. Selected strains were subjected to different acid levels (pH 2.5–6.0) and bile concentrations (1.0–3.0%). Strains were also evaluated for their antimicrobial activity by agar spot test. The potential probiotic strains tolerated pH 3.5 and above without statistically significant growth reduction. However, at pH 2.5, a significant (p < 0.05) growth reduction occurred after 1 h for L. plantarum (4.32 log CFU/mL) and B. longum (5.71 log CFU/mL). S. cerevisiae maintained steady cell counts for the entire treatment period without a statistically significant (p > 0.05) reduction (0.39 log CFU/mL). The results indicate at 3% bile concertation, 1.86 log CFU/mL reduction was observed for L. plantarum, while S. cerevisiae, and B. longum growth …

Probiotics are live microbial feed supplements that promote growth and health to the host by minimizing non-essential and pathogenic microorganisms in the host’s gastrointestinal tract (GIT). The campaign to minimize excessive use of antibiotics in poultry production has necessitated development of probiotics with broad application in multiple poultry species. Design of such probiotics requires understanding of the diversity or similarity in microbial profiles among avian species of economic importance. Therefore, the objective of this research was to establish and compare the microbial profiles of the GIT of Guinea fowl and chicken and to establish the microbial diversity or similarity between …
