How does giving tulathromycin at birth impact the fecal microbiota?

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’s Science Page presents the second part of a project done by Zeineldin et al. from Dr. Jim Lowe’s program at the University of Illinois. The first part is available here.


  • Fluctuations in antimicrobial resistance genes (ARGs) associated with the developing gastrointestinal microbiota have not been elucidated
  • The swine fecal microbiota and their accompanying ARGs were diverse and established soon after birth
  • Results indicate that the perinatal TUL metaphylaxis has no measurable beneficial or detriment impacts on fecal microbiota structure and abundance of ARGs in pre-weaned piglets
