Winter arrives, coats thicken, and lice populations tend to explode—quietly cutting gains, damaging hides, and even causing anemia. We sit down with Thach Winslow DVM, a veteran beef cattle veterinarian and technical consultant, to map out a clear, workable plan for winter lice control that protects herd health and the bottom line.

We start by breaking down how lice survive summer heat in protected areas and why they surge as cattle “hair up.” Dr. Winslow explains the difference between chewing lice that irritate skin and sucking lice that draw blood and can debilitate animals, and he quantifies the real costs: lost weight, facility damage from rubbing, and downgraded hides. From there, we tackle strategy. You’ll hear why early treatment sets you up for a rebound, what the old two-pass system got right and wrong, and how modern options that target both adults and eggs can deliver season-long control—if you hit the window when winter truly settles in.

Application makes or breaks success. We share the exact placement from forehead to tailhead, why a stream nozzle beats a shower pattern, and how to get product onto the hide where lice live. Miss one animal and you risk reseeding your entire herd, so we cover simple checks to avoid costly do-overs. We also address real-world constraints: using temporary knockdowns when processing comes early, planning a return visit for the definitive treatment, and troubleshooting re-emergence without jumping to resistance.

If winter lice have ever blindsided your herd, this conversation gives you a plan to act with confidence. Treat late, treat right, and treat every head. If you find this helpful, follow the show, share it with a neighbor, and leave a quick review so more producers can dial in their winter health protocols.

Hunger rises fastest when good intentions collide with bad rules. We sit down with Brazil’s poultry leader, Ricardo Santin, to unpack how a country at the heart of global protein supplies is navigating animal diseases, as avian influenza; biosecurity; vaccination, and fair trade—without pricing families out of a meal. Ricardo shares data on Brazil’s production scale in chicken, pork, and eggs, then walks us through the real-world costs of blanket trade bans. The science is clear: properly handled and cooked meat doesn’t spread avian influenza, yet many markets still shut their doors, driving up prices for the poorest consumers.

We dig into One Health thinking—protecting animals, people, and the environment together—and why biosecurity remains the first line of defense. When diseases become endemic, vaccination matters, but markets have to recognize it. Ricardo makes the case for extending regionalization, zoning, and compartmentalization to vaccinated areas just as we do for outbreak zones. That shift protects flocks while keeping protein affordable, and it secures access to genetic material that low-income countries rely on to sustain their poultry sectors. Along the way, we explore the roles of WOAH, FAO, and national authorities in turning science-based standards into consistent, fair trade practices.

If you care about global food security, this conversation offers a pragmatic playbook: align policy with evidence, reward prevention, and design rules that keep safe food moving. We close with a simple principle that doubles as a challenge to policymakers and industry alike: There should be no borders for food. If this resonated, share it with a friend, leave a review, and subscribe so you never miss a candid look at where animal health meets our dinner tables.

Calves don’t read the playbook, so we wrote one that actually works on the ground. We brought in Dr. Jeremi Wurtz, a beef cattle technical consultant and veterinarian, to map out a clean, science-first path from the first sip of colostrum to a calm, productive post‑weaning period. The focus is simple: reduce stress, build immunity, and protect gains with choices that pay back in healthier calves and better margins.

We start where lifetime health really begins—colostrum. You’ll hear why poor passive transfer can multiply BRD risk and how that early immunity shapes everything that follows. From there, we get practical with low-stress weaning: fence-line or two-step approaches, gentle handling that keeps cattle thinking instead of reacting, and the small facility tweaks that make processing days smooth. Then we stack a smart vaccine plan on top, dialing in timing so calves get a priming dose before separation and a booster after they settle.

Nutrition and preconditioning take center stage as we talk bunk training, water access, and the role of ionophores like Rumensin in boosting average daily gain, feed efficiency, and coccidia control. If you’re developing heifers, you’ll learn how small efficiency gains bring more heifers into puberty earlier, improving conception rates and lifetime productivity. If you’re shipping steers to a feedlot, we outline how to hit intake fast and hold health steady to lower cost of gain. Finally, we dig into parasite control with real numbers.
