More specifically the ask was about presenting on biosecurity practices that we do, should do or should stop doing to control endemic diseases in pigs. This was not an easy task since the interplay between biosecurity and disease occurrence is complex. 

Here are a few messages I shared.

Dr. Perle Zhitnitskiy recognized with the Zoetis Distinguished Teaching Award

Dr. Zhitnitskiy of the UMN Swine Group is at the forefront of integrating new technology into her classroom, a trait that recently earned her the Zoetis Distinguished Teaching Award, the most prestigious teaching honor bestowed by the CVM. Each year, the winners are chosen by faculty and veterinary students.
