This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
This week, Dr. Albert Canturri from the Torremorell lab is sharing results on a study looking at udder skin wipes and piglet nasal wipe to detect swine influenza.
Continue reading “Which wipes are better to detect flu: udder skin or nasal wipes?”
- Various wipe types can be used to sample IAV from the udder skin of lactating sows. Although differences between wipe types were not seen, wipes that were wet provided a better detection rate than dry wipes.
- Furthermore, wiping the nose of 5 piglets within a litter resulted in higher litter detection rates than sampling the udder directly. This indicates that within litter prevalence is a driver for IAV detection using wipes.
- Future steps are needed to assess differences in virus isolation among sampling procedures.
In this new publication from the Journal of Veterinary Medical Education, Dr. Perle Zhitnitskiy from the UMN swine group, in collaboration with Dr. Beth Ventura explores the impact that various educational initiatives have on first-year veterinary students attitudes towards swine production.
Continue reading “Vet Student Attitudes about Swine Change after Lecture and Farm Visit”
- First-year students undergo 1-hour lecture and one farm visit in their first year of the curriculum.
- Knowledge and attitudes towards pigs improved after the educational initiatives.
- Students became more segmented in their overall view of swine production.
- Provision of enrichment did not increase students’ satisfaction with the level of animal welfare on the farm.
Today, we are sharing a publication from Drs. Davies and Singer regarding antimicrobial use in wean-to-market pigs in the United States based on self-reported data from swine producers and veterinarians. This work is published in Zoonoses and Public Health in open access.
Continue reading “Antimicrobial use in wean to market pigs in the United States”
- Demonstrates the feasibility of obtaining data on antimicrobial use in the United States swine industry through sharing of proprietary records within industry.
- Provides the first substantial description of antimicrobial use in United States swine beyond annual sales and distribution data.
- Indicates that specific metrics of antibiotic use that focus on conditions within individual industries will be most useful to advance stewardship.
A review paper was recently published in the Transboundary and Emerging Diseases journal, result of a collaboration between the University of Minnesota and Alexandria University. In this publication, available in open access, researchers describe the survival rates of the virus on various surfaces and the impact of temperature and humidity.

Dr. Alyssa Betlach, member of the Maria Pieters Myco Lab, recently published a study on the natural transmission of Mycoplasma hyopneumoniae in Veterinary Microbiology. The study evaluated transmission rate in a naïve gilt population and compared various sample types to detect infection.
