Enzymes naturally occur in many biological systems to either facilitate the digestion of their target substrates or aid simple organisms to defend themselves. Unlike ruminants, poultry species such as chickens do not have the enzymes necessary for the hydrolysis of brous compounds, such as the non-starch polysaccharides (NSP).
Thus, it has become common practice to supplement poultry diets with NSP-degrading enzymes, such as xylanase, cellulase, and -glucanase, to degrade NSP present in raw materials, which in turn, increase the digestibility of nutrients.
The primary benefits of NSP degrading enzymes have been associated with increased nutrient digestibility and reduced viscosity. However, it is recently understood that NSP degrading enzymes, specially those with the capability of generating oligosaccharides in situ, has the potential of improving GIT microbial ecology.
It is within the scope of this webinar series that several world-renowned scientists and in-house experts of Kemin are invited to shed some light on this subject and explore the shift of focus for feed enzymes in this new post-AGP era.

Prof. Knud Erik Bach Knudsen
Professor in Basic Nutrition at Aarhus University, Department of Animal Science, Denmark
Knud Erik Bach Knudsen is a professor in Basic Nutrition at Aarhus University, Department of Animal Science, Denmark. For more than 35 years, Knud Erik Bach Knudsen has been working with different aspects of carbohydrates and phytochemicals. Working areas have been to develop new analytical methods for the characterisation of carbohydrates in feeds, foods, and digesta materials, analyses of carbohydrates in a wide variety of feedstuffs, studies on nutritional and physiological properties of carbohydrates particularly in pigs but also in other non-ruminant species, and investigations of the role of carbohydrates in prevention of digestive disturbances and establishment of parasites in pigs. In recent years Knud Erik Bach Knudsen has also been involved in several projects related to nutrition and health properties of carbohydrates and phytochemicals in the borderline between animals and humans.
After completing his Ph.D., Knud Erik Bach Knudsen worked at the Carlsberg Research Centre and The Royal Veterinary and Agricultural University, Copenhagen, before joining the Danish Institute of Agricultural Sciences; from 2007 Aarhus University. He has been author and co-author of more than 265 papers in peer-reviewed journals, mainly related to analytical, nutritional, physiological, and health aspects of carbohydrates and phytochemicals.
Oligosaccharides and The Implication on Productivity and Gut Homeostasis
Alexandra Wealleans, Ph.D.
Innovation Project Manager at Kemin Animal Nutrition and Health
Alex Wealleans is an animal scientist with Kemin Animal Nutrition and Health, where she leads research to improve the nutrition of pigs and poultry – and the ways that improved nutrition also improves their health and welfare. Her Ph.D. research focused on “pannage” pigs, whose diet of acorns and beech mast had interesting – and unexpected – impacts. Since then, she has focused on the use of feed additives, in particular enzymes, and always looks to relate the complicated scientific interactions between feed and the gut environment back to the industry’s wider mission and purpose: healthy, efficient animal production that allows people the world over to have access to nutritious, balanced diets.
