More than 140 feed industry professionals met in in Paris on the 23rd and 24th of October to discuss latest research and nutritional solutions for poultry and swine production. With the challenges addressed including feed costs and raw material quality; as well as optimizing productivity taking into account intestinal health and improving sustainability.
Chairing the meeting Pierre-Andre Geraert explained, “at Adisseo we believe it is important to understand exactly the issues producers are facing, which is why we have asked world renowned scientists to present their research. For example, there is much talk about gut health but there are so many reasons for problems including, digestibility, immunity, gut integrity. It is important to get to the bottom of the issue so that the most suitable solution can be found for them.”
Opening the first session Marcio Ceccantini discussed the nature of the indigestible fraction of monogastric diets, before explaining how the feedase concept can be used to obtain optimum technical and economic performance. Dr Estelle Bonnin from INRA, delved further into the topic by describing the diversity of cell wall polysaccharides found in major feed ingredients, in particular non-starch polysaccharides (NSP). “We need to respond to the diversity of polysaccharides, by using multiple and highly specific enzyme preparations.” Specifically addressing phytate, Professor Markus Rodehutscord from the University of Hohenheim explained, “P and Ca supplements strongly reduce InsP6 degradation but phytase can compensate in a dose-dependent manner. Phytase has a strong effect on P and Ca availabilities and myo-inositol release. Investigating changes to the plasma metabolome profile will also help to better understand further benefits of phytase.”
Dr Pierre Cozannet went into more detail on enzyme substrate relationships, focusing on arabinoxylans. “Arabinoxylans are antinutritional for both poultry and swine, and can be degraded by carbohydrases, improving the nutritional value of the diet and animal performance. Optimising equations are now available to calculate the benefits of a feedase based on the arabinoxylan content of the diet.”
The ‘pro-prebiotic’ effect of enzymes was discussed by Dr. Lamya Rhayat. “We have seen that by releasing more useful nutrients, the microbiota shifts towards butyrate and acetate producers. This in turn reduces inflammatory responses in the gut and enhances immune defences.”
