Veterinary students: It’s not too late to apply for Morrison Swine Innovator Prize! Share your work at the Allen D. Leman Swine Conference; it’s a great opportunity for veterinary students who want to network with industry leaders.
The Allen D. Leman Swine Conference includes a session for veterinary students to demonstrate their problem-solving skills through the presentation of a case or experience where students challenged their clinical training and problem-solving capabilities necessary for day-to-day practice. Creativity and originality in the support and delivery are encouraged. The session will take place in-personduring the afternoon of Sunday, September 18 at the Allen D. Leman Swine Conference and will include presentations from 7 veterinary students. Invited students will receive a $1,000 stipend and free admission to the Leman Swine Conference.
Submissions to enter in the selection to present at the DVM student session at the Leman Conference should be uploaded at z.umn.edu/MSIP by August 15th at the end of the day.
If you have any questions, please contact Dr. Zhitnitskiy at firstname.lastname@example.org. For more information about the Morrison Swine Innovator Prize visit z.umn.edu/MSIP.
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.
First, 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.
Then, 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 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 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.
The recipients of the Pijoan and Leman fellowships were revealed last week and we are proud to announce that two great candidates were selected.
Dr. Eliana Silva Paladino is receiving the Carlos Pijoan fellowship. Eliana obtained her DVM and MS degrees in Brazil and is currently a PhD student advised by Dr. Julio Alvarez. Eliana’s PhD is focusing on the application of quantitative tools for the management of problems of relevance to the swine industry at both the farm and population (i.e., supra-farm) levels. She is currently focusing on developing systems to quantify the effect of endemic diseases such as swine influenza and the management strategies adopted for their control in affected farms. She is also working on the assessment of trends in submissions received at veterinary diagnostic laboratories over time to evaluate the impact of changes in disease distribution, diagnostic approaches and farm management in the U.S.
Dr. Jose Angulo is receiving the Allen Leman fellowship. Jose obtained his DVM degree in Mexico and is currently a PRRS specialist and managing veterinarian for Zoetis in charge of U.S. customers. Jose will be completing his Masters in Dr. Montse Torremorell’s lab and his work will focus on understanding PRRS infections in growing pigs and how to prevent them.
Title: Epidemiological investigation of a non-reportable endemic disease: Porcine reproductive and respiratory syndrome (PRRS) in the US
Presented by: Pablo Valdes-Donoso
Date:Friday, June 9, 2017 Time: 3:00 – 4:00 pm Place: 385-J, AS/VM Building
Abstract: Porcine reproductive and respiratory syndrome (PRRS), caused by a highly mutagenic and resistant RNA-virus, is an endemic disease that has been noted as one of the most important animal production diseases in the US because of its large economic damage on the swine industry. Nonetheless, there is no official control framework for this disease, so producers rely on voluntary regional control programs (RCPs) for its mitigation. Despite efforts to control PRRS, it persists in the environment, affecting a large number of farms every year. Using information shared by a specific RCP (RCP-N212), this dissertation focused on important aspects of PRRS dynamics within an RCP. Specifically, this dissertation encompassed five chapters. An introductory chapter is followed by the second chapter, which quantifies the extent to which RCPs contribute to PRRS control. After that, a prediction of network structure was made to forecast animal movements among farms within the RCP-N212. Then, longitudinal data collected from sow farms were used to measure the impacts of PRRS on production. Finally, a disaggregated disease diffusion model was used to depict PRRS dynamics within the RCP-N212, as well as to evaluate individual and collective strategies adopted by producers. This dissertation provides insight to the evaluation of regional control strategies that may be used as a framework for a formal PRRS control program.
