A Deeper Dive
Here are three "Angus at Work" episodes focused on managing pests.
October 21, 2025
Considering recent headlines focused on the pests that plague — or could plague — our herds and us, now is an ideal time to reflect on these pests, whether they’re flying, parasitic or more insidious. Here are a handful of Angus at Work episodes that cover topics worth considering back at home.
For a large portion of the United States, the previous year has been one for the books. Plentiful rain and green grass — even in areas that usually can’t claim anything green except for the bar ditches — are cause for celebration.
However, with that moisture comes its own unique set of challenges. Those challenges often materialize as nuisances that can cause tail swishing, bunching, overstimulated and stressed cattle. But there is a reemerging insect on the horizon that threatens to take the concern for fly control to another level.
On this episode, Sonja Swiger with Texas A&M AgriLife Extension discusses the usual culprits, why flies are an issue, how to control flying insects and the lowdown on New World screwworm.
“The other fly species we already talked about. Yeah, they’re a nuisance, but they’re not going to kill the animal if it’s born in the springtime. Having calves in the summer and spring? Well, it is literally the death of them because this fly will come in and lay its eggs on the umbilical cord and will almost 100% kill that animal if it’s not tended to.” — Sonja Swiger
One concern that can keep any cattle producer hopping? Cattle health.
Whether preventing the issue before it has a chance to begin or monitoring the health of fed cattle across a larger operation, ensuring cattle are living up to their full potential takes time and resources that can be hard to come by.
This episode features two interesting interviews by Angus Beef Bulletin Editor Shauna Hermel at CattleCon25. First up is Eric Moore, director of technical services with Norbrook, who shares insight on efficient parasite control that won’t harm existing beneficial insects.
Then, Jason Nickell, director of insights and outcomes for Merck Animal Health and Ross Havens, marketing coordinator for Nichols Farms, share the science behind SenseHub Feedlot, as well as insight on how SenseHub performs in the real world.
“If we look at the interaction of animals and wildlife that we have, there’s always a source for something. You may not have brought an animal into your herd, but they’ve been exposed somewhere down the line from animals coming through. So if we want to prevent the damage to our facilities, prevent the hair loss, prevent the hide damage, prevent the weight loss or lack of gain, then we need to make sure we do that up front.” — Eric Moore
Here at the Angus Beef Bulletin, our staff works to provide you — our subscribers — the most up-to-date information regarding health, nutrition, marketing, genetics and management. When we had the opportunity to interview a Kansas veterinarian at Angus Convention 2024 about a company working to provide effective vaccinations for immediate animal health concerns, we knew we had to bring you the information. On this episode, Bob Gentry, key account manager with Medgene Labs discusses with Editor Shauna Hermel how Medgene’s “platform technology” allows vaccines to safely and easily adapt to multiple animal disease targets, why a quick response to newly emerged illnesses is critical, and which vaccinations are available from Medgene.
“We make our vaccine very similar to how human — or exactly in some cases — how human vaccine is made. We have the ability to take advantage of a production system that is not new, but new to the livestock vaccine arena. So we have vaccines that couldn’t be produced before, such as the bovine papilloma.” — Bob Gentry
