Weeds, Especially Challenging This Year in Both Pastures and Hay Fields!

By Victor Shelton

Weather has been the biggest variable again this year, and it’s made clear just how different conditions can be from one farm to the next. From my own place in southwest Indiana, we’ve had more rain than we’d like, while others nearby have been dealing with the opposite. No one set of observations covers every situation, so what I share each month comes from what I see at home, along with farm visits, conversations with producers and the questions and challenges you pass along. My goal is to offer ideas and principles you can adapt to your own conditions—rain or shine.

Weeds have been especially challenging this year across both pastures and hay fields. Prolonged periods of either excessive rainfall or drought have stressed desirable forage species, opening the door for opportunistic and often toxic weeds to expand. When cool-season grasses and legumes are weakened, weed species are quick to exploit the gaps.

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.
