The gastrointestinal tract (GIT) microbiota of production animals are firmly established as key features that underpin animal health, development, and productivity. Early gut colonization is of particular importance affecting the GIT morphology, and local and systemic biochemistry, and immunology of the animal with critical impacts on nutrition, and neonatal resistance to pathogenic challenge. Although perturbations of an animal’s GIT microbiota can occur at any age with profound consequences, perturbations during early GIT development can be particularly severe and have significant and long-lasting sequelae.
With that in mind our group has set out to determine the earliest and most significant influences on the neonatal GIT microbiota and its corresponding relationships with health, immune development and efficacy, and nutritional efficiency. Our ultimate goal is to develop smart strategies based on basic science to optimize the GIT microbiome to benefit the health and performance of agricultural livestock species.
