Title: Gastric ulcer syndrome in exercising horses fed different types of hay
Author: Lybbert, Travis Craig
Abstract: Equine gastric ulcer syndrome (EGUS ) is highly prevalent in horses and most commonly found in racing and performance horses . This condition may negatively impact the health and athletic performance of affected horses (Vatistas et al . 1999 ) . Proton pump inhibitors are commonly used to treat EGUS , however , a less expensive method , such as a change of diet , may give similar results . Alfalfa hay may offer some buffering capabilities within the stomach (Nadeau et al . 2000 ) . The objective of this study was to further investigate any possible antiulcerogenic properties of alfalfa hay . Twenty -four Quarter Horse yearlings , 12 -16 months of age , were utilized in this study . The 77 -d experiment consisted of two 28 -d periods separated by a 21 -d wash -out period . Horses were endoscopically examined at the beginning and end of each period and blocked into two treatment groups . Treatment 1 included coastal bermuda grass (CB ) hay and Treatment 2 included alfalfa hay as the only forage source . Horses were fed in stalls , housed in small dry lots , and subjected to an exercise regimen using a mechanical horse -exerciser . A significant effect of diet , was observed on ulcer score (P < 0 .05 ) . CB hay ?fed yearlings experienced an increase in ulcer score severity compared to that of alfalfa hay ? fed yearlings . Significant healing did not occur during the wash -out period , but horses experienced a significant increase in ulcer score severity (P < 0 .05 ) . The outcome of this study suggests that alfalfa hay does have antiulcerogenic capability .
