Dewormers aren’t working the way they used to, and treating the whole herd may be part of the problem. Dr. Leonor Sicalo Gianechini, a parasitologist at the University of Georgia, explains how drug resistance develops and why targeting only the animals that need treatment, dosing by actual weight, and combining drug classes can keep dewormers effective longer. She also lays out a simple five-step plan that cattle, sheep, and goat producers in the Southeast can start using right away to cut parasite losses on their operations.

Marcelo Wallau shares the latest updates on pasture mealybug and its growing impact on forage production across Florida. He discusses ongoing research into insecticide effectiveness, forage susceptibility and biological control, along with current recommendations for identifying and managing infestations. As researchers work to better understand the pest, this episode highlights emerging strategies to improve long-term resilience.

In this episode of Cow Talks, host Marcelo Wallau sits down with Dr. Dean Pringle, the new chair of the University of Florida Department of Animal Sciences, to talk about his plans for the department, including a stakeholder-driven strategic plan. Dr. Pringle introduces the Animal Products Excellence Center (APEX), a revitalized meat science hub meant to connect genetics, nutrition, and management on the ranch to the Florida consumer.

In this episode of Cow Talks, host Marcelo Wallau is joined by Dr. Clyde Fraisse, professor of agrometeorology in UF's Agricultural and Biological Engineering Department, to break down the strong El Niño forming in the Pacific and what it could mean for Florida this fall, winter, and spring. They discuss the higher odds of above-average rainfall along with why this may be a good year to invest in cool-season forages.

Marcelo Wallau talks with a panel of industry agronomists and nutritionists about growing corn and sorghum silage in the Southeast. They cover this season's challenges, such as late frosts, dry weather, nematodes, and the tight timelines dairies work underm and what those mean for fiber digestibility. The group also discusses where sorghum fits in the rotation and why hybrid selection matters less than solid management and a good crew.

In this Cow Bites technical segment, host Marcelo Wallau sits down with Maria Elena Mailhos, variety trial coordinator for the UF/IFAS Forage Team, to walk through the results of the 2025–26 cool-season forage variety trials. Trial results, reports, and the three-year regional recommendations (developed with the University of Georgia and Auburn University) are available on the UF/IFAS Forage Team website: https://programs.ifas.ufl.edu/forage/official-variety-trials/ Questions? Reach the team at [email protected], or come see the varieties in the field at the annual cool-season forage field day in late February.

Crop insurance is an increasingly important tool for managing the production and price risks facing farmers and ranchers. In this episode, Dr. Hunter Biram of the University of Arkansas breaks down how federal crop insurance works and how it complements Farm Service Agency programs. The episode dives into discussion about what producers should know about coverage options. The conversation also explores Pasture, Rangeland, and Forage (PRF) insurance, livestock risk protection, basis risk, and how cattle producers can use these programs to manage production challenges.

Hannah Baker speaks with Dr. Marcelo Wallau about the latest pressures facing the U.S. beef cattle industry, from the announcement of increased beef imports to the reopening of the Mexican border and recent beef packing plant closures. They discuss how these developments are affecting cattle prices and decisions about herd rebuilding. Given the market turmoil, producers are left navigating a great deal of uncertainty, which this episode aims to clarify.

Pasture mealybug continues to spread across Florida, with new detections raising questions about how the pest is moving and why damage is appearing in some pastures but not others. In this update, Dr. Brent Sellers and Dr. Isaac Esquivel discuss the latest field observations, early detection, insecticide use, and strategies for managing affected pastures during the stockpiling season. They also share emerging findings and highlight the many questions researchers are still working to answer.

In this presentation, Dr. Mary Beth Hall explores how Florida's unique growing conditions shape forage quality and availability. She discusses the importance of balancing digestibility and effective fiber to support rumen function, while considering how forage type, maturity, processing and environmental conditions affect animal performance. The presentation also examines practical considerations for both dairy and beef cattle producers.

How can producers reduce winter feeding costs while maintaining forage quality? In this episode of Our Research in Perspective, UF graduate researcher Olivia Centanni shares findings from her master's research on fall forage stockpiling, rumen digestibility, and silage production in warm-season grasses. Learn which forage species perform best and why fertilization timing matters. Olivia also draws on her data findings, and how these management decisions can improve both cattle nutrition and profitability.

In this special joint episode with Grazing the Facts, host Dale Sandlin sits down with Marcelo for an in-depth conversation about the future of forage management in Florida.Marcelo shares his journey from growing up on a cattle ranch in southern Brazil to leading statewide forage extension and research programs in Florida. The discussion explores practical strategies for improving pasture productivity while also increasing forage diversity, and building resilient grazing systems in the face changing weather conditions across the state.The episode also highlights research supported by the Florida Cattle Enhancement Board, including forage variety trials and the importance of helping producers make science-based management decisions that improve both profitability and sustainability.

On July 17th 2026, UF IFAS Forages joined FDACS and the Everglades Research and Education center for an informative webinar on pasture mealybug science, management, and what we know so far.For more information, please visit: https://go.ufl.edu/pasturemealybugs

Recorded live at the 2026 Florida Cattlemen's Convention in Marco Island, this special episode features Dr. Marcelo Wallau's presentation on his firsthand experience growing up with New World screwworm in southern Brazil. He shares practical lessons on proactive management that can help Florida producers. He also provides an update on the recently detected pasture mealybug, discussing what researchers know so far about its spread and the ongoing efforts to develop effective management strategies. Whether you're a cattle producer, forage manager, or simply interested in invasive species, tune in for timely insights into Florida agriculture.

As New World screwworm continues spreading north through Mexico toward the U.S., entomologist Dr. Andrew Short joins Cow Talks during the Florida Cattlemen's Convention in Marco Island, FL, with Dale Sandlin and Marcelo Wallau to explain what the latest detections mean for Florida and the Southeast. The conversation covers how the pest spreads and why increased surveillance and rapid reporting are critical to protecting livestock. Dr. Short also discusses ongoing coordination among state and federal agencies and producer outreach to ensure the region is prepared should screwworm reach producers.    Relevant links: More on Dale and AGNet here: https://southeastagnet.com/author/dsandlin/ Listen to Grazing the Facts here: https://southeastagnet.com/grazing-the-facts-podcast/ New World Screwworm from FDACS here: https://www.fdacs.gov/Agriculture-Industry/Pests-and-Diseases/Animal-Pests-and-Diseases/New-World-Screwworm
