IMPACT OF ENZYMES AND FIBRE ON GUT HEALTH Xavière Rousseau, AB Vista Balchem Real Science-Lecture Series 08th June 2021
OUTLINES 1. Gut and health 2. Enzymes beyond nutritional matrix value 3. Fibre : what’s new and how to optimise their inclusion to ensure good gut health
GUT AND HEALTH FREE OF ILLNESS WITH HIGH ABILITY TO COUNTERACT ANY ENTERIC CHALLENGE (gut epithelium = physical and chemical protection from the antigenic components) EVERYTHING THAT ALLOW EFFECTIVE NUTRIENT DIGESTION – ABSORPTION - FERMENTATION GUT INTEGRITY GUT FUNCTIONALITY (absorption (immunostimulation – - pathogens- homeostatic inflammatory balance) response) 1. Ensure Effective digestion and absorption (digestion-absorption process) 2. Having an optimal and balanced microbiome + Limit pathogens growth (gut integrity) + beneficial fermentation 3. Good immune status (innate and acquired mucosal immune response) and low inflammatory response

PHYTASE APPLICATION IN GUT HEALTH Increase digestibility of protein => lowering putrefaction in the hindgut Cowieson et al, 2015 Releasing key nutrients : Zn, Cu, Fe that have beneficial effect on gut health Increase ALP activity by Zn release to produce more inositol • Reduction of enteric inflammation => Weaning diahrroea decrease • Need to consider very high level of phytase to produce relevant concentrations of inositol antioxydant effect => woody breast • Better blood oxygenation : woody breast and ascites incidence reduction

CONCLUSIONS Gut health is dependant on many factors => nutritional tools are available to get animals able to ensure optimal gut integrity and capacity to cope with any gut challenges 1. Enzymes are relevant tools by their effect in increasing nutrient digestibility of protein, amino acids, minerals, fibre but there is probably much more to extract than we thought. Targeting maximum inositol release can help to control diarrhoea in piglets and breast myopathies incidence : high dosage of phytase application 2. Controlling the AXOS arriving in the hindgut to get beneficial fermentation : NSPase 3. Having a better monitoring of fibre characteristics and understanding the requirement of the animals to adapt the fibre fraction would be a key as to help for a proper and quick adequate microbiome establishment All the 3 above are relevant tools , are interlinked and the strategy needs to be adjusted following the target
TAKE HOME MESSAGE Think also enzymes application beyond nutritional matrix & Look at fibre as the feed for gut microbiome
