In this episode of The Poultry Nutrition Blackbelt Podcast, Dr. Elijah Kiarie from the University of Guelph discusses the nutritional challenges of β-mannans in soybean meal and the value of β-mannanase supplementation in poultry diets. He breaks down the metabolic, immune, and microbiome effects of fiber and how enzyme technologies are advancing feed efficiency. Listen now on all major platforms!

"β-mannanase supplementation helps neutralize β-mannans, improving nutrient absorption and reducing immune activation."

Meet the guest: Dr. Elijah Kiarie received his Ph.D. and postdoctoral training in monogastric nutrition from the University of Manitoba. He is a Professor at the University of Guelph and holds The McIntosh Family Professorship in Poultry Nutrition. His research bridges fundamental and applied science to advance poultry productivity through innovations in early-life nutrition, enzyme technologies, and sustainable feed strategies.
