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: Sweetener Effects on Gut Health - Dr. Kwangwook Kim

In this episode of The Swine Nutrition Blackbelt Podcast, Dr. Kwangwook Kim, Assistant Professor at Michigan State University, discusses the use of non-nutritive sweeteners in nursery pig diets. He explains how sucralose and neotame influence feed intake, gut health, metabolism, and the frequency of diarrhea compared to antibiotics. The conversation highlights mechanisms beyond palatability, including hormone signaling and nutrient transport. Listen now on all major platforms!

“Receptors responsible for sweet taste are present not only in the mouth but also along the intestinal tract.”

Meet the guest: Dr. Kwangwook Kim / kwangwook-kim is an Assistant Professor at Michigan State University, specializing in swine nutrition and feed additives under disease challenge models. He earned his M.S. and Ph.D. in Animal Sciences from the University of California, Davis, where he focused on intestinal health and metabolic responses in pigs. His research evaluates alternatives to antibiotics, targeting gut health and performance in nursery pigs.
