In this special edition of The Real P3, Dr. Casey Bradley brings together all four interviews from the NOVUS book launch event for Nutrition and Production Strategies for Today’s Sows. This episode highlights the collective expertise of leaders shaping the future of sow health, performance, and longevity.
From amino acid evolution to heat stress, micronutrition, and reproductive management, these conversations reflect how rapidly the modern sow has changed—and what producers, nutritionists, and veterinarians must understand to support her success.
We begin with Dr. Laura Greiner (Iowa State University), who explains how sow nutrition has transformed over the last 25 years. She walks us through the shift from simple lysine-based feeding to precision nutrition, technology-driven management, and understanding lactation amino acid transitions.
Next, Dr. Brad Lawrence (Novus International) challenges long-held assumptions about trace minerals. He dives into bio-utility versus bioavailability, new insights from biomarkers and gene expression, and how mineral source directly influences sow and offspring performance.
Our third conversation features Dr. Timothy Safranski (University of Missouri), one of the industry’s foremost reproductive physiologists. He breaks down the genetic and environmental pressures shaping reproduction today, especially how heat stress affects puberty, estrus, farrowing rate, boar fertility, and long-term herd outcomes.
We close with Dr. Antonio Palomo (Spain), offering a global perspective on the alarming rise in sow mortality. This segment includes an English voiceover summarizing his in-person Spanish interview. Dr. Palomo reveals why sow deaths are now largely metabolic rather than infectious, and why micronutrition—vitamins, minerals, oxidative stress reducers—may be the key to reversing this trend.
Whether you're a nutritionist, production manager, veterinarian, or student of swine systems, this combined episode captures the essential knowledge shaping the future of sow performance.
Special thanks to NOVUS International for their continued investment in research, global collaboration, and producer education.
You can watch the full four-part video series on YouTube, including the Spanish-language version of our conversation with Dr. Palomo.
