Fibre fermentation and the possible role of butyrate in pig health

Fri, 08 Nov 2019 00:00:00 GMT

Speaker: Dr Helle Nygaard LAERKE (Aarhus Univ, Denmark)

Presentation:
Butyrate, either endogenous (produced by microbiota) or exogenous (supplied by the feed) is a key nutrient for gut metabolism: reducing intestinal inflammation, improving absorptive capacity, strengthening gut barrier resulting in better performance and better meat quality.

Swine: Managing Sows
Managing sows starts with improving their feed intake, particularly in lactation. Manipulating the feed composition to stimulate endogenous butyrate production, to improve quantity and quality of colostrum and milk will help to support prolificity and piglet performance.

The use of exogenous butyrate, and the stimulation of endogenous intestinal...

Salmonella is colonizing the ceca. Thus, butyrate needs to be protected to have an effect against Salmonella through a clear anti-virulence effect by downregulating virulence genes. A large part of antimicrobial use is for intestinal disorders and coated butyrate supplementation shows a reduction in Necrotic enteritis (Clostridium perfringens) occurrence.
Butyrate is a key molecule for strengthening gut integrity, reducing gut inflammation and improving tight junctions. Lots of gut bacteria are butyrate producers helping promoting a better gut health and as feed supplement could further reduce necrotic enteritis and other gut dysbiosis. Cecal butyrate producing bacteria can be stimulated with dietary xylan-oligosaccharides which further increases cross-feeding lactate to butyrate using bacteria.

Roundtable with Experts on phosphorus

Mon, 05 Feb 2018 00:00:00 GMT

Speakers: Prof Layi Adeola from Purdue Univ, USA; Prof Markus Rodehutscord, Univ of Hohenheim, Germany

We need to move toward a common methodology to measure phosphorus availability and determine P requirements: going away from non phytate P to Total Ileal Tract Digestibility of P.

From feedstuffs to enzyme supplementation: how to get more P available and to reduce the indigestible P through a better knowledge of substrates and enzyme activities.

Round table with Experts on phosphorus

Two worldwide experts on phosphorus share their ideas on how to determine P availability within feedstuffs and P requirements of poultry and swine.

Fibres in layer diets: properties and nutritional functions

Tue, 23 Jan 2018 00:00:00 GMT

Speaker: Knud Erik Bach Knudsen

Dietary fibres: key feedstuffs to optimize layer nutrition. From adverse to beneficial effects.

Fibres are important components of the layer diets, often more diluted than broiler ones. Having a better knowledge of the characteristics of those fibres will help to better value them. The fibre fraction is represented by carbohydrates and lignin which cannot be digested by the endogenous enzymes. The most important functional properties of fibres are related to solubility and viscous properties in the gut and the encapsulation of potentially available nutrients. Exogenous enzymes can be used to alleviate some of the negative effects of the fibre in relation to feed intake, digestibility and nutrient utilization.
