Nationwide events find
all horses at risk for EGUS.
Gastroscopy events at veterinary clinics and university campuses in 25 states identified stomach ulcers in a surprising number of horses:1
- 658 total horses participated.
- Horses from 1 to 41 years old were identified with stomach ulcers.
- 254 horses that were diagnosed with stomach ulcers had no previous history of ulcers.
- Horses with stomach ulcers were stabled in a wide range of environments, including box stalls, pipe stalls, a pasture alone and a pasture with other horses.
- Horses fed supplements like beet pulp, flaxseed and corn oil were still identified with stomach ulcers — regardless of the discipline (click the individual discipline links in the table below for more information).
