Dr. Urbano Ruiz: Age Specific Nutrient Matrices | Ep. 215

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Urbano Ruiz, Professor at the University of São Paulo, explains how amino acid and phosphorus digestibility change as pigs grow. He shares research showing major differences across production phases and highlights the impact of fiber and physiology on nutrient use. Learn how age specific nutrient matrices can improve performance and sustainability. Listen now on all major platforms!

“Adopting different nutrient matrices for pigs according to age can be very important for swine production efficiency.”

Meet the guest: Dr. Urbano Ruiz is a Professor at Luiz de Queiroz College of Agriculture, University of São Paulo, Brazil. For over 15 years, his research has focused on swine nutrition, including nutrient digestibility, alternative ingredients, feed additives, and sustainable pig production. His work evaluates amino acids, phosphorus, fiber, and energy utilization across growth stages.
