Disinfection of Maternal Environments Is Associated with Piglet Microbiome Composition from Birth to Weaning

Abstract

We show that levels of disinfection in farrowing facilities can impact early microbial exposures and colonization by pioneer microbes in piglets. Although previous research has shown a similar effect by raising pigs outdoors or by exposing them to soil, these practices are unattainable in most swine production systems in the United States due to biosecurity practices.
