Abstract

This project comprised three studies aimed at determining the impacts that feeding non-starch polysaccharides (NSP) have on aspects of gastrointestinal tract (GIT) structure and function, production, and circulating measures of physiology and immune function. Experiment 1, ‘Virulence testing and serotyping of an enterotoxigenic E. coli (ETEC) isolate’, was directed at confirming the nature of the E. coli isolate used at Murdoch University in controlled infection studies. Experiment 2, ‘Determining the insoluble fibre requirement of weaner pigs when fed a diet containing either a low or high level of soluble fibre’, used the same E. coli isolate to infect pigs after weaning and examine the effects of soluble and insoluble fibre on post-weaning diarrhea (PWD), production, and physiological responses. Experiment 3, ‘Reducing the risk of E. coli by establishing a fibre recommendation after weaning’, was a commercial validation study conducted at CHM Westbrook based on the findings from Experiment 2.
