It’s important that all the players in an industry speak the same language, and the Reproduction/Perinatology Forum on Dec. 3 at the American Association of Equine Practitioners convention in Seattle, Wash., tried to help equine veterinarians do just that. The main topic of discussion was the updating of several reproduction-related terms and definitions in the AAEP position statements in the annual membership directory and resource guide.


Moderators Steven Brinsko, DVM, MS, PhD, Dipl.

  • Pregnant
  • Not pregnant
  • Aborted
  • Mated
  • Mating
  • Suitable for mating
  • Stillborn
  • Neonatal death
  • Foal died
