Mycoplasmas in swine: a new comprehensive book

Dr. Maria Pieters, head of the MycoLab at the University of Minnesota has edited, in collaboration with Drs. Dominiek Maes and Marina Sibila, a newly published book on swine Mycoplasmas. Mycoplasmas in Swine provides up-to-date scientific, clinical and practical information useful to scientists and veterinarians alike. Most emphasis has been placed on Mycoplasma hyopneumoniae, as this is economically the most important Mycoplasma sp. in swine. However, other pathogenic species like Mycoplasma hyorhinis, Mycoplasma hyosynoviae and Mycoplasma suis are discussed.

ASF and PED alter China swine production: a podcast

Podcasts are a perfect way to get caught up with new swine information! We are presenting you the latest episode from “At The Meeting… Honoring Dr. Bob Morrison” in collaboration with SwineCast.

‘At The Meeting’ Honoring Dr. Bob Morrison¬†focuses on how African Swine Fever (ASF) and Porcine Epidemic Diarrhea virus (PEDv) have driven changes in farm design and biosecurity in China, allowing China’s swine industry to regain an estimated 80 percent of its swine herd.

Which wipes are better to detect flu: udder skin or nasal wipes?

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.

Key points

  • 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.

Vet Student Attitudes about Swine Change after Lecture and Farm Visit

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.

Key Points

  • 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.

Survival of swine pathogens in compost formed from preprocessed carcasses

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, we are sharing a summary of a study published by Dr. Brent Pepin et al. from Pipestone Veterinary Services on the survival of swine pathogens in compost.

Key Points

  • Composting of preprocessed carcasses effectively eliminated infective PRRSV/PED under cold weather conditions
  • Compost biomass type (carbon source) may affect the short-term virus survival¬†
  • Environmental viral contamination (aerosolization and groundwater) from carcass preprocessing and windrow composting appears minimal under the conditions of the study
  • Compost reached temperatures that can adequately deactivate ASF
