8:15 a.m. - 4:30 p.m. George Foxcroft Reproduction Workshop

In recent years, selection for robustness has been a key component of most breeding programs. But what is a robust sow? A robust sow will be better able to meet their genetic potential and have a long and productive life in a variety of different challenges. It is true that “gilts are the foundation of the breeding herd”, however, to help her meet her potential we must support her development. In this session we will discuss several key management aspects necessary to unlock the genetic potential of the robust sow, such as, selection for soundness, novel phenotypic traits, as well as gestation and lactation management.

Organized in collaboration with the University of Alberta

1:00 - 5:00 p.m. Geeks to Geeks: Strategies, challenges, and opportunities for ASF early detection and surveillance

The African Swine Fever (ASF) pandemic has caused devastating losses to affected countries over the last 15 years. In its role as a collaborating center for the World Organization for Animal Health, and a reference center for the Food and Agriculture Organization of the United Nations, the University of Minnesota Center for Animal Health and Food Safety (CAHFS) leads several capacity-building and research activities in ASF-infected countries. Join the CAHFS team and a selection of guest speakers to discuss the latest news, experiences, and recent developments to enhance ASF preparedness and response.
