| Summary: | <p>Probiotics are an alternative to increase broiler productivity and flock health. For this reason, the objective of the first study was to evaluate commercially available <i>Bacillus</i> spp. based probiotic products on their ability to reduce <i>Salmonella</i> Heidelberg, <i>in vitro</i>. Results showed that most products reduced the lower concentrations of <i>S. Heidelberg</i> and maintained a reduction for up to 8 h. The second study was conducted to determine if bacterial colonization occurred in a broiler chick after <i>in ovo</i> injection. Using bioluminescence, it was demonstrated that bacteria could migrate and colonize the embryo within 2 h after <i>in ovo</i> injection into the amniotic fluid. The results of these studies demonstrated that probiotics could reduce pathogenic microorganisms and can potentially have a positive impact on the chick before it even hatches and is placed in a broiler house. </p> |
