Case-control study of the association between various management factors and development of colic in horses. Texas Equine Colic Study Group.

The association between various management factors and development of colic was studied in 821 horses treated for colic and 821 control horses treated for noncolic emergencies by practicing veterinarians in Texas between Oct 1, 1991 and Dec 31, 1992. History of previous colic and history of previous abdominal surgery were found to be significantly associated with colic. Change in stabling conditions during the 2 weeks prior to the time of examination, recent change in diet, and recent change in level of activity significantly increased the risk for development of colic. Changes in activity level, diet, and stabling conditions were identified as potentially alterable risk factors for colic. Logistic regression was used to adjust for the effects of all variables found to be significantly associated with colic by means of univariate analysis, and only history of previous colic, history of previous abdominal surgery, and history of recent change in diet remained significantly associated with colic. Results of this study indicate that a proportion of colic cases might be prevented by minimizing changes in management practices.
