Beer and Bacon conversations: a new session at the Leman swine conference!

The organizing committee of the Allen D. Leman swine conference is proud to present a new session: Beer and Bacon conversations! The goal of this unique session is to invite industry leaders to share personal views and experiences with participants in a fun and relaxed environment.


This year, we are honored that Dr. Matthew Turner, veterinarian and head of pork live operations at JBS, accepted our invitation.

A graduate of North Carolina State University College of Veterinary Medicine, Dr. Turner joined JBS after being a staff swine veterinarian for Prestage Farms for more than 10 years. He was recognized by the American Association of Swine Veterinarian as the 2014 Swine Practitioner of the year and presented the Dr. Alex Hogg Memorial Lecture at the 2017 AASV annual meeting. Dr. Turner is currently an at large member of the Board of Directors of the Swine Health Information Center (SHIC).

The session will be held at the InterContinental hotel on Sunday, September 16th at 5:15pm. Dr. Marie Culhane will get the conversation started but participation from the audience is more than welcome!

Seating for this event is limited. Do mot miss out by registering today!

The swine group is presenting its research around the world: come see us at the 2018 IPVS!

The summer has just started and our faculty and graduate students have attended multiple conferences to share the latest and most advanced results of their research. Do not miss them at the 2018 IPVS!

Two UMN graduate students awarded at CRWAD

The first week-end of December was the Conference of Research Workers in Animal Diseases in Chicago. Several of the swine group graduate students were presenting their work and received an award.

NC1202 Student Award 3First, Frances Shepherd received the award for best oral presentation in the Enteric Diseases category for her presentation titled Variability and bioinformatic analysis of porcine rotavirus B and C illustrate potentially important immunological sites. Frances’ advisers are Dr. Douglas Marthaler and Dr. Michael Murtaugh.

AVEMP Student AwardsThen, Dr. Robert Valeris received the best poster award in the Veterinary Epidemiology and Preventative Medicine category for presenting Survival analysis of protocols for eradication of Mycoplasma hyopneumoniae in swine farms.

Join us in congratulating our students for their awards!


The U of MN well represented at the NA PRRS Symposium

The first week-end in December is usually the time of the North American PRRS symposium. This year did not upset the tradition but this time, the conference was in collaboration with the National Swine Improvement Federation.

The 2017 NA PRRS meeting was dedicated to Dr. Bob Morrison.

The meeting was dedicated to our friend and colleague Dr. Bob Morrison. A memorial fellowship organized by Dr. Montse Torremorell (U of MN) and Dr. Joan Lunney (USDA) provided travel support to future scientists who wish to follow in his footsteps.

Stephen Gerike from the Pork Checkoff shared information on the state of pork products used in restaurant. Bacon represents 20% of products used but is still growing (+4% since last year).

Stephen Gerike shared the updated cooking recommendations for pork product.

 Overall, 82% of restaurant customers eat the same or larger amount of pork which is a good trend for the industry. Mr. Gerike also shared the efforts done by Pork Checkoff to convince consumers to not overcook their pork. Reminder: 145F is safe. “Cook your pork like you cook your steak!”


The University of Minnesota was well represented during the conference. Dr. Montse Torremorell moderated the Saturday morning session on PRRS in the field. Drs. Cesar Corzo, Carles Vilalta and Juan Sanhueza shared the updates on the Morrison Swine Health Monitoring Program as well as regarding the studies that they are involved with. Take away messages:

  • MSHMP is now collecting information from 50% of the sows in the United States.
  • Based on this data, 58% of the farms breaking with PRRSV today will break again within a year.
  • PRRS summer outbreaks happen and vary based on location (see figure below).
  • Farms take a longer time to reach stability after a summer outbreak (median 41.5 weeks)
  • Processing fluids can be used as a monitoring method for PRRS.

Dr. Perle Boyer shared the launching of an online course designed in collaboration with Iowa State University regarding genetic resistance to PRRSV. The course will be open in Spring 2018 and is designed for swine health professionals, veterinarians and experts who want to know more about the Principles and application of genetics and genomics to improve animal health.
