From 2003 to 2004, 770 horses were followed up for the incidence of colic cases. A descriptive analysis of clinical data, incidence of colic cases and rate of horses affected was established. Chi-squared test was used to evaluate the association among colic syndrome and variables related to horses characteristics and management. Colic syndrome incidence varied among military units as follows: 0.12 cases/horse-year at AMAN, 0.21 at EEC and 0.95 at REsC, affecting 15% of horses in AMAN, 30% in EEC and 69% in REsC. The highest incidence was of gastric episodes (76.5%). Recurrence cases were 62.5% in REsC, 36.7% in AMAN and 29.0% in EEC. Colic syndrome occurred associated with variables: military unit, management, amount of intake grains and supplemented mineral-vitamin. High incidence, recurrence and horses rate with colic were differentiated among the three units. Although the horses of military units had common characteristic , they formed a heterogeneous group in respect to colic syndrome occurrence, probably due to different management conditions.
