Small Pests, Bigger Threats: Flies and Gnats Spread Swine Rotaviruses and Sapovirus

Annoying. Bothersome. Irritating. Inconvenience. Pest. No matter how you describe Musca domestica, aka the house fly, and its friend the gnat, one thing's for sure - they are a nuisance and pose a threat to your swine herd.

Everyone knows the small stature of flies and gnats and their ability to fly allows them to easily enter and exit barns and vehicles while bringing with them viral, bacterial and parasitic pathogens. For the first time ever, a study led by Allison Knox of the Walcott Veterinary Clinic in Walcott, Iowa, shows the ability of house flies and gnats to transmit rotavirus and sapovirus in swine nurseries.

Evolution of Beef Cattle Farming

Video: Evolution of Beef Cattle Farming

The Clear Conversations podcast took to the road for a special episode recorded in Nashville during CattleCon, bringing listeners straight into the heart of the cattle industry. Host Tracy Sellers welcomed rancher Steve Wooten of Beatty Canyon Ranch in Colorado for a wide-ranging discussion that blended family history and sustainability, particularly as it relates to the future of beef production.

Sustainability emerged as a central theme of the conversation, a word that Wooten acknowledges can mean very different things depending on who you ask. For him, sustainability starts with the soil. Healthy soil produces healthy grass, which supports efficient cattle capable of producing year after year with minimal external inputs. It’s an approach that equally considers vegetation, animal efficiency, and long-term profitability.

That philosophy aligned naturally with Wooten’s involvement in the U.S. Roundtable for Sustainable Beef, where he served as a representative for the Colorado Cattlemen’s Association. The roundtable brings together the entire beef supply chain—from producers to retailers—along with universities, NGOs, and allied industries. Its goal is not regulation, Wooten emphasized, but collaboration, shared learning, and continuous improvement.
