Microbiota is necessary for the development of Immune system

Tue, 23 Oct 2018 00:00:00 GMT

Speaker: Prof Bernd KASPERS, Inst Vet Medicine, Univ Munich, Germany

The gut immune system (lymphocytes B and C, macrophages, dendritic cells…) is the largest immune tissue in the body and is the first to have to deal with pathogens and other ingested xenobiotics. A diverse and well-developed microbiota is necessary for the development of an efficient immune reaction avoiding inflammation response. But immune system is also involved in controlling intestinal microbiota.

Redox balance at the gut level: from dietary antioxidants to microbiota

Tue, 23 Oct 2018 00:00:00 GMT

Speaker: Prof Peter SURAI, Feed-Food Ltd, Scotland, UK

Redox balance in the gut is critical to guarantee gut homeostasis. Lots of Reactive Oxygen Species are produced at the gut level in relationship with its high metabolism and exposure to mycotoxins, oxidized fat, microbiota. Maintaining the optimal balance between pro-oxidant and anti-oxidant compounds is thus important to guarantee gut efficacy. Selenium-based anti-oxidants have demonstrated their importance to protect gut from oxidation.

Intestinal functionality: the dichotomy between nutrient and barrier function

Wed, 26 Sep 2018 00:00:00 GMT

Speaker: Prof Todd APPLEGATE, Poult Sci Dept, Univ Georgia, USA

The gut is adaptive and responds to ingredient matrix and bacterial environment. But these responses can alter endogenous maintenance as well as nutrient and energy digestibility. The gut response to pathogens depends on their amount, their virulence and of predisposing factors (e.g. cocci, mucin type, etc.). Gut immunological responses may vary nutrient “needs” with changes in tissue maintenance needs and nutrient use efficiencies.

Strengthening intestinal frontier: key for performance (introduction)

Tue, 25 Sep 2018 00:00:00 GMT

Speakers: Prof Mingan CHOCT, Univ New England, Australia; Pierre-André GERAERT

The intestinal wall is the last digestive frontier before the blood and has to face absorbing nutrients and avoiding entrance of unfavorable bacteria and dietary components. Worldwide experts explore levers to strengthen the intestinal frontier to support optimal performance.

Phytate can be significantly degraded in the intestine but dietary Ca and P supply may drastically affect this degradation. It is thus important to avoid excess in minerals to guarantee efficacy of endogenous and exogenous, mucosal and bacterial, phytase activities.

Amino Acids: key for the functioning of intestine

Tue, 25 Sep 2018 00:00:00 GMT

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.

Tue, 25 Sep 2018 00:00:00 GMT

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.

Probiotics: Effects on gut barrier and inflammation

Tue, 25 Sep 2018 00:00:00 GMT

Speaker: Dr Estelle DEVILLARD, Health by Nutrition R&D Team, Adisseo, France

At each level of digestive health (microbiota, mucosal barrier, immune tolerance, redox system), balance must be maintained. Probiotics can act at the four levels involved in digestive health. Their effects are strain specific. The mechanisms involved are under investigation, but at least involves the production of bioactive compounds.

Speaker: Dr Ferry Poernama, Feed Tech & Nutrition Director, Japfa Comfeed, Jakarta, Indonesia

Heat stress not only means hot temperatures but also high humidity and eventually heat spikes. Farm management with controlling the ambient temperature is key. Heat stress reduces performance but also challenges immunity, disease resistance and nutritional basis.

Specific dietary appetites in broilers with hyperthermia

Thu, 05 Apr 2018 00:00:00 GMT

Speaker: Prof Eugeni Roura, Queensland Univ, Brisbane, Australia

The 1st consequence of heat stress is a reduced feed intake. Modern broilers appeared more sensitive to protein than energy intake also under hot conditions. Stimulating the specific appetite for amino acids may be a good lever to improve performance under heat challenges.

Speaker: Prof Ravindran, Poultry Science Department, Massey Univ, New Zealand

Nutrient digestibility is often reduced under hot conditions, but nutrient utilization is even more depressed leading to less protein retention independently of reduced feed intake.
