How various non-AGP strategies can reduce the systemic effects of inflammation

Thu, 22 Aug 2019 00:00:00 GMT

Speaker: Dr Doug KORVER Univ of Alberta, Canada

Presentation:
Non-antibiotic strategies to control gut microbes, may directly or indirectly affect systemic inflammation. Thus, only using different and complementary alternative solutions with different mechanisms would appear efficient to help reduce medication and maintain productivity.

The bird and its ecosystem:
A global approach for an efficient production.
How to work with a complete and dynamic ecosystem is the challenge facing today’s nutritionist. Having a global and integrative view of how the intestinal microbiome and the animal’s body function together is the basis of sustainable nutrition.

Plenary Session 3 – Gut health – take on new approaches

The 22nd European Symposium on Poultry Nutrition organized in Gdansk, Poland last June, reached a new attendance record with more than 1800 participants.

Why do we need to understand microbial pathogenesis?

Tue, 02 Jul 2019 00:00:00 GMT

Speaker: Prof Mark STEVENS, the Roslin Institute & the Royal School of Vet Studies, Univ of Edinburgh, UK

Identification of microbiota associated with pathogen resistance may lead to rationally selected probiotics and feed additives. Editing, ablation and adoptive transfer of components of the immune system will be key tool to dissect avian responses required for protection.

Speakers: Prof Filip VAN IMMERSEEL, Faculty Vet Medicine, Ghent Univ, Belgium

New technologies are promising to develop biomarkers of gut health. The most important would be to have predictive biomarkers to anticipate gut health disturbance. Today, macroscopic (ballooning, tonicity, residues…) and microscopic (villi, tight junctions, …) observations help to better appreciate gut health condition but inflammation, immune parameters and microbiota are also important. Microbiota signature is associated with gut disorders, but microbial functional activity is even more predictor of such dysbiosis.

Amino Acids: key for the functioning of intestine

First pass of Amino Acids supplies the intestinal AA requirement. Males and females exhibit difference in AA requirement that should be better taken into account. Challenging conditions (dirty environment or sub-clinical Clostridium infection) significantly increase the demand for lots of amino acids among with Threonine and BCAA. Arg needs also increase under cocci challenge.

The intestinal frontier integrity: the tight junctions

Tue, 25 Sep 2018 00:00:00 GMT

Speaker: Dr Raquel MARTIN-VENEGAS, Fac Pharmacy, FFUB, Barcelona, Spain

The selectivity of the intestinal frontier is ensured by the good functioning of the tight functions. Their complex protein structure helps to ensure the intestinal frontier integrity and most of the absorption through the enterocytes and the transcellular pathway. Dietary solutions, such as OH-Met, pro- and pre-biotics can strengthen the tight junctions and thus the intestinal frontier.

Speaker: Dr Fabrice LAURENT, Avian Pathology Department, INRA, France

Parasites affect the intestinal integrity. Innate immunity is important, particularly for neonates and young animals, in controlling pathogens in the intestine. Immuno-stimulation of innate immunity is a promising strategy for controlling parasite development. Host microbiota composition is not only important for intestinal immune development but also to modulate host response during infection or immunomodulatory treatments. An optimal microbiota may thus help to resist to parasite challenge.

Gut integrity: a hard topic for nutritionists but challenging for animal performance and has to be taken into account in feed formulation. What are the practical biomarkers to evaluate the gut integrity, a true challenge for the future? What can we use to strengthen gut immunity, minimize endogenous losses, thus to optimize bird performance?

Speaker: Prof Filip VAN IMMERSEEL, Vet Medicine, Ghent Univ, Belgium

Mucosa-associated bacterial communities are important for gut health. Butyrate-producing bacteria seem essential. Feeding strategies (eg prebiotics such as AXOS, probiotics) can steer towards butyrogenic (mucosa-associated) taxa in the gut. Biomarkers of the host response are important tools for the development of future efficient gut health solution. Butyrate, even from dietary origin, seems to have potency to reduce effect of pathogens in the intestine.

The gut under hot climates: challenging microbiota

Thu, 05 Apr 2018 00:00:00 GMT

Speaker: Prof Richard Ducatelle, Ghent University, Belgium

The most metabolically active cells are the epithelial cells of the intestine, thus the most susceptible cells to oxidative stress. Heat stress is one of the stress factors challenging the intestine from the microbiota to the mucosa.

What about intestinal barrier or intestinal integrity?

Fri, 15 Dec 2017 00:00:00 GMT

Speakers: Prof Richard DUCATELLE, Prof Filip VAN IMMERSEEL

The intestinal lumen represents where the outside world is in closest contact with the blood. Integrity of the intestinal wall and strong tight junctions are key for healthy gut.

The size of the feed particles is also an important parameter affecting gut microbiota. Prof Richard Ducatelle and Filip van Immerseel debate on the importance of the gut and its microbiota on the performance of the animals. Knowing better the indigestible part is key to improve gut functioning.
