Antimicrobial use in wean to market pigs in the United States

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.

Impacts

  • 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.

Production losses from a recombinant PRRSv outbreak

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 bringing to you a summary from a publication by the SEGES Danish Pig Research Centre and the University of Copenhagen in Denmark. The study published in Porcine Health Management describes production losses associated with a recombinant PRRS strain in breeding herds.

Key Points

  • A new PRRS-1 recombinant between two vaccine strains variant was reported.
  • This variant was detected in a boar station and affected breeding and production herds.
  • Production losses associated with this variant in the production herds comprised a decrease in liveborns/litter and in weaned/litter, as well as an increase in stillborn/litter which was higher than observed in previous Danish PRRS outbreak reports.

A review of SARS-CoV2 and other coronaviruses survival in the environment

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.

Natural transmission and detection of Mycoplasma hyopneumoniae in a naïve gilt population

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.
