What are the best diagnostic tools for tracking Mycoplasma hyopneumoniae in swine?

M. hyopneumoniae causes one of the swine industry’s most devastating diseases—a chronic, infectious pneumonia that can cause respiratory distress and lung lesions in pigs. It can also severely slow pig growth. In order for producers and veterinarians to best measure the success of their disease control and elimination efforts, they need to be able to detect the pathogen in live pigs. However, many diagnostic tools can be unreliable. Dr. Maria Pieters’ lab at the University of Minnesota College of Veterinary Medicine recently led a study to decipher the reliability of two tools, laryngeal swabs and deep tracheal catheters, in detecting the pathogen.

Best of Leman 2019 #3: Three systems views on PRRS decreasing incidence

This is a favorite on the blog. Once a month, we are sharing with you a presentation given at the Allen D. Leman swine conference, on topics that the swine group found interesting, innovative or that lead to great discussions.

We can find all of the presentations selected from the previous years’ conferences on the blog here.

A few days ago, we shared a report that PRRS incidence decreased in naive breed-to-wean farms. Interesting questions were brought forward by our readers so this month, we are sharing three practitioners’ experiences with PRRS in their systems: Dr. Tara Donova with the Hanor company, Dr. Jay Miller with The Maschhoffs, and Dr. Pete Thomas from Iowa Select Farms.

What do US producers and veterinarians think about antibiotic-free production?

This recent open-access publication in Frontiers expends beyond the realm of swine production and raises the question raising animals without using antibiotics. Dr. Singer from the University of Minnesota in collaboration with multiple other institutions surveyed US producers and veterinarians to gather their thoughts on the topic.
