Remembering Bob Morrison

This month marks the 5th anniversary of Dr. Bob Morrison’s passing, and we at Morrison Swine Health Monitoring Project (MSHMP) and the UMN Swine Group want to commemorate him and his extensive and meaningful work. In the years since Bob’s death, many people have spoken and written about his professional contributions nationally and internationally to academia, research and the swine industry.

DVM students: apply to the Morrison Swine Innovator Prize!

Veterinary students: Are you shadowing a swine practitioner this summer or have you been involved in an interesting clinical case investigation? Did you work on your veterinary skills by designing a differential diagnosis list or working on a treatment plan? Did you investigate a problem by analyzing production records? Share your work at the Allen D. Leman Swine Conference to win the Morrison Swine Innovator Prize!

Attending the Leman Conference is a great opportunity for veterinary students who want to network with industry leaders. Submissions to enter in the selection to present at the DVM student session at the Leman Conference should be uploaded at by August 15th at the end of the day.

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-person during 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.

If you have any questions, please contact Dr. Zhitnitskiy at For more information about the Morrison Swine Innovator Prize visit

Swine Veterinary Education in the US: current challenges and opportunities

Antimicrobial use, PRRS, and the microbiome with McKnight Land-Grant Professor Noelle Noyes

Dr. Noelle Noyes received the 2022 McKnight Land-Grant Professorship for her work on Microbes for Sustainable Intensification of Livestock Production. As the human population expands, so does its demand for protein. Livestock farmers must meet this demand, but their land and water are shrinking rapidly, meaning they must produce more with less. Dr. Noyes confronts this challenge through scientific discovery of the livestock microbiome.

Noyes receives 2022 McKnight Land-Grant Professorship

In one of their latest studies in collaboration with Pipestone Systems and Dr. Peter Davies, the Noyes lab evaluates the impact of antimicrobial use on resistance patterns in PRRS-infected pigs. The publication is available in open access in the Applied and Environmental Microbiology journal.

Despite a recognized need for more longitudinal studies to assess the effects of antimicrobial use on resistance in food animals, they remain sparse in the literature, and most longitudinal studies of pigs have been observational. The current experimental study had the advantages of greater control of potential confounding, precise measurement of antimicrobial exposures which differed markedly between groups and tracking of pigs until market age. Overall, resistance patterns were remarkably stable between the treatment groups over time, and the differences observed could not be readily reconciled with the antimicrobial exposures, indicating the likely importance of other determinants of antimicrobial resistance at the population level.
