Secretary Naig Comments on EPA’s Amended Waters of the United States Rule

Iowa Secretary of Agriculture Mike Naig released the following statement today after the Environmental Protection Agency (EPA) released an amended Waters of the United States rule: 

“The Supreme Court made it abundantly clear in Sackett v EPA that the Environmental Protection Agency and the Army Corps of Engineers overstepped their legal authority and therefore must re-work their overly broad, confusing and burdensome Waters of the United States rule. Unfortunately, while this latest amendment does include some positive movement, the amended rule continues to overreach resulting in uncertainty. I would encourage the Biden Administration to head back to the drawing board, listen to stakeholders from Iowa and across the country and finally fix the rule.”

Video: Methionine Requirements for Lactating Sows - Cierra Kozole


In this episode of The Swine Nutrition Blackbelt Podcast, Cierra Kozole, PhD candidate in Swine Nutrition at the University of Guelph, explains how methionine supports lactating sows beyond milk protein synthesis. She discusses updated requirement estimates, source comparisons, methylation demand, and why modern sow genetics may require more precise amino acid strategies. Listen now on all major platforms!

"Methionine supports protein synthesis while also serving critical functions through methylation pathways that influence multiple biological processes."

Meet the guest: Cierra Kozole / cierra-kozole-772b64253 is a PhD candidate in Swine Nutrition at the University of Guelph in Canada. Her doctoral research focuses on refining estimates of methionine requirements for primiparous lactating sows, including evaluating methionine sources, nutrient partitioning, methylation reactions, and the links among amino acid supply, milk production, and sow protein retention.
