Approaches to identify biomarkers for intestinal health and the first tools...

Tue, 02 Jul 2019 00:00:00 GMT

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.

Gut microbiota as the gate to the organism: modulating and filtering nutrients

Fri, 28 Jun 2019 00:00:00 GMT

Speaker: Prof Marc-André SELOSSE (NMNH, France)

Presentation:
The gut microbiota can be considered as the door to the animal’s body influencing both the nutrients and the gut health and thus a potential buffer of the variability between ingredients

Variability: the nutritionist’s nightmare:

How to monitor its impact to improve feed formulation?

Feed is the largest contributor to the cost of animal protein production. It is therefore, the main cause of uncertainty and anxiety for nutritionists and feed formulators. Dealing with variability to prepare consistent feeds is the objective of nutritionists worldwide.

There are no bad raw materials… only wrongly evaluated and incorrectly used raw materials.

Butyrate: a key functional regulator for the intestinal mucosa

Wed, 24 Apr 2019 00:00:00 GMT

Speaker: Prof Hervé BLOTTIERE, MICALIS & INRA, Paris, France

We are an holobiont, an ecosystem of micro-organisms and host cells. The intestinal microbiota is a stable community in healthy humans producing a lot of metabolites among with butyrate is important.
The early exposure to poor bacterial diversity will compromise immune response and favors gut disorders and other diseases including cardiovascular and brain ones. Dietary fibres are essential dietary components that will help supporting a rich microbiota promoting a better global health.

Butyrate is an energy source for colonocytes, controls cell proliferation, stimulates mucus production, inhibits inflammatory responses, regulates intestinal macrophage function, inducing T-reg cells, inhibiting histone-deacetylase thus impacting overall metabolism. Butyrate has also been shown as AHR nuclear ligand new pathway, having thus strong effect on immune response in humans.

Dietary modulation of gut microbial short-chain fatty acid metabolism

Wed, 24 Apr 2019 00:00:00 GMT

Speaker: Dr Petra LOUIS, the Rowett Institute, Aberdeen, UK

Microbiota has multiple functions and effects on the host: barrier against pathogens, immune interactions, release and transform dietary phytochemicals, xenobiotics and host metabolites, produce short chain fatty acids that influence host health.
Non digestible carbohydrates or fibres are important substrates for this gut microbiota as well as resistant starch greatly influence the microbiota composition and metabolism. More than the individual bacteria types, the metabolic bacterial network is important through the cross-feeding between fibre-degrading, oligosaccharide users, lactate or acetate producers which will give substrate for butyrate producers. Some carbohydrates are more butyrogenic or propionigenic. Similar interactions exist in amino acids and proteins within the microbial community. Future will be based on modelling microbiota metabolism showing that interactions between microbes, environment (pH, …) and dietary substrates (indigestible fractions) are essential.
