Accurately defining our nutrient loadings when formulating diets is essential for nutritionists. If we are not accounting for enough enough energy from hindgut fermentation, we may be over feeding energy during certain stages of production. In this episode with Dr. Ruurd Zijlstra, we discuss a study he conducted measuring the digestible and fermentable fractions of certain grains to hopefully more accurately predict the net energy of these feedstuffs. Take a few minutes and give this a quick listen!


Meet the guest: Dr. Ruurd Zijlstra is Professor at the Department of Agricultural, Food and Nutritional Science at University of Alberta, Edmonton, Canada. He was born and raised in The Netherlands where he completed a M.Sc.-degree at Wageningen University. In 1996, he completed a Ph.D. at the University of Illinois and was first for 8 years at Prairie Swine Centre in Saskatoon, Canada as Research Scientist – Nutrition. He has produced 161 scientific papers and 12 book chapters on nutrition topics. His current research program is focused on unique aspects of starch and fiber nutrition, nutritional quality of co-products in pigs, and feed quality evaluation techniques. He received the 2018 Nonruminant Nutrition Award of the American Society of Animal Science – American Feed Industry Association.
