Nutritional strategies to reduce the impact of Escherichia coli in newly weaned pigs

Abstract

Low crude protein, added insoluble fiber, and low acid-binding capacity diets, as well as pharmacological zinc oxide (when applicable) are important nutritional strategies that can be used to maintain the gastrointestinal health of weanling pigs exposed to Escherichia coli. Feed additives including probiotics, exogenous enzymes, egg yolk antibodies, spray-dried plasma, clays, medium-chain fatty acids, phytogens, and antibiotics may be other options to reduce the impact of E coli. Management strategies such as vaccine protocols, colostrum management, barn and water line sanitation, and weaning age should be combined with nutritional interventions to minimize diarrhea caused by E coli.
