Abstract
Insoluble non-starch polysaccharides (iNSP) can decrease enterotoxigenic E. coli (ETEC) shedding in the gastrointestinal tract (GIT) and reduce post-weaning diarrhoea (PWD), whilst higher levels of soluble NSP (sNSP) have been associated with increased PWD (Pluske et al. 2002). A number of mechanisms such as reduced retention time, inhibition of mucosal E. coli adhesion and proliferation of butyrate-producing bacteria have been suggested to explain the beneficial effects of more iNSP in the diet (Lindberg 2014). However associations between dietary iNSP levels, specific microbial species and effects on production and ETEC shedding after weaning have not been explored in detail. The hypothesis tested was that pigs fed iNSP would have a higher abundance of butyrate-producing bacteria that in turn is correlated to indices of production and ETEC shedding.
