Defining and validating gut health criteria in young pigs, based on digestive physiology, microbiology and mucosal immunology investigations for testing alternative strategies to in-feed antibiotics

Objective

The EU expects health degradation of pigs at weaning in intensive production systems after the recent ban on in-feed antibiotics and metals. Many alternatives with claimed effectiveness have invaded the market prior to being fully evaluated. Our objective is to provide scientific basis for understanding the functional disturbances of the gut, which favour enteric infections. We propose to use the disturbed weaned pig as a model for defining the major criteria for gut health. We will measure the changes occurring in gut physiology and digestion, mussel integrity and function, bacterial populations, and intestinal immunity, using the most modern techniques. The ability of selected novel feed additives and rearing strategies to maintain or restore gut health will be assessed in large pig trials using the most pertinent defined health criteria. This will contribute to set up a uniform approach to testing alternatives at the EU level and will assist socio-economical partners in making well-informed decisions.
