S3E226 - 12m - Jun 4, 2026 - Dr. Rosero and Dr. Borg: Going Beyond Feed Formulation to Maximize Profitability | Ep. 225
Drs. David Rosero and Bart Borg discuss the introduction of a new online financial model that estimates the economic value of nutritional strategies to maximize growth potential and profit per pig. Feed4Profit, developed by Iowa State University in collaboration with U.S. Soy, integrates multiple user inputs, including diet formulation, predicted growth performance, and future pricing for ingredients and pigs.
“Users can design feeding programs with different ingredients, model the performance response, and compare the forecasted income and feed costs over a 12-month period.” David Rosero, PhD, Iowa State University
“Seasonal changes in pig performance is one example of how nutritional strategies can impact profitability. This tool can help nutritionists analyze the financial impact of adjusting these feeding programs, while still meeting minimum nutritional requirements.” Bart Borg, PhD, Passel Farms
Meet the guests:

S3E225 - 15m - May 28, 2026 - Grady Privett: Sorghum Inclusion in Sow Lactation Diets | Ep. 224
In this episode of The Swine Nutrition Blackbelt Podcast, Grady Privett, a graduate student at Kansas State University, discusses research evaluating sorghum as a replacement for corn in lactation diets for sows. He discusses particle-size management, feed intake, energy value, and commercial-mill considerations when using sorghum in swine production systems. Learn how sorghum can support sow and litter performance in practical operations. Listen now on all major platforms!
"Sorghum can replace corn in lactation diets when particle size is controlled, and feed mills avoid whole berries in finished feed."
Meet the guest: Grady Privett is a graduate student in Animal Sciences at Kansas State University with experience in swine production, nutrition research, and commercial farm operations. His work focuses on nutritional strategies to improve sow and litter performance, including the inclusion of sorghum in lactation diets.
