Vaccine innovation helps swine producers stay ahead of PCV2

Jan 23, 2023

Since emerging as a major pathogen 20 years ago, porcine circovirus type 2 (PCV2) has become a fact of life for swine producers. “Virtually every farm is infected,” says Dr. James “Jamie” Lehman, DVM, MS, swine technical services veterinarian for Merck Animal Health. “It’s just a challenge of managing your immunity both in the sow herd and among your piglets.”

A large part of Dr. Lehman’s job is working with producers and veterinarians to troubleshoot PCV2 health problems. He sees pigs with PCV2 infections exhibiting poor growth rates, lethargy and skin lesions.1 Understanding the dynamics of each herd helps Merck Animal Health recommend PCV2 vaccine protocols that create the most positive outcome.

“We support customers with diagnostic plans and herd visits as needed, getting to know the operation and help plan the investigation.” Dr. Lehman says. “Every case is different, depending on the age of pig affected.”

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.
