Insights
Intra-abdominal pressure (IAP) significantly increases in horses during and after cribbing behavior. This study compared IAP in cribbing horses to non-cribbing horses, finding elevated pressures in the cribbing group.
Area of Science:
- Equine physiology
- Gastrointestinal health
- Animal behavior
Background:
- Cribbing is a common vice in horses.
- The physiological effects of cribbing on intra-abdominal pressure (IAP) are not well understood.
Purpose of the Study:
- To measure and compare intra-abdominal pressure (IAP) in horses that exhibit cribbing behavior versus those that do not.
Main Methods:
- A cohort study design was employed.
- Intra-abdominal pressure (IAP) was measured using a microsensor catheter in 8 cribbing and 8 non-cribbing horses.
- Pressures were recorded for 2 hours while horses were standing in stalls.
Main Results:
- Baseline IAP did not differ significantly between groups.
- IAP was significantly higher in cribbing horses during active cribbing behavior.
- Elevated IAP persisted in cribbing horses even after the behavior ceased.
Conclusions:
- Cribbing behavior in horses is associated with increased intra-abdominal pressure (IAP).
- This elevation in IAP occurs both during and after the act of cribbing.
Objective:
To measure intra-abdominal pressure (IAP) in horses that crib and compare it with IAP in horses that do not have this vice.
Study Design:
Cohort study.
Animals:
Healthy cribbing horses (cribbing cohort, n = 8) and 8 healthy noncribbing horses (noncribbing cohort).
Methods:
A microsensor catheter was introduced into the peritoneal cavity through the right paralumbar fossa, using local anesthesia, for measurement of IAP. These pressures were recorded in 1-minute intervals for 2 hours, while the horses were standing tied in a stall. IAPs of cribbing horses were compared to the noncribbing cohort.
Results:
Baseline IAPs were not significantly different between cribbing and noncribbing cohorts (P = .076); however, IAPs in the cribbing cohort were significantly increased when compared with the noncribbing cohort, during active cribbing behavior (P = .0016). Frequency of cribbing was not associated with increased IAP (P = .35). IAPs in the cribbing cohort remained significantly elevated compared with the noncribbing cohort, even after the behavior had ceased (P = .0002).
Conclusion:
Cribbing is associated with increased IAP in the horse, both during and after the behavior.

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
