Abstract A total of 90 native breed draft horses of both sexes were studied; 75 cases exhibited clinical signs of gastro-intestinal colic (47 females and 28 males). Of all, 15 apparently healthy horses were randomly selected and were considered as a control group. Moreover, nine apparently healthy donkeys were subjected to experimental study. Their ages ranged from 10-15 years old. The present study was planned to highlight on the most common types of gastro-intestinal colic in equines, to evaluate the usefulness of a wide range of individual clinical and clinico-pathological parameters specially blood gases and anion gap in formulating prognosis. Experimental induction of obstructive colic in donkeys was aimed to simulate the naturally occurring field cases. It could be concluded that Blood gases and anion gap determination were suggested as diagnostic and prognostic aid for the equine practitioners. Their significances were not only for diagnosis of acid-base disturbances, predicting the survival rates and site of affections in horses with colic, but also for formulating a plan for the convenient fluid therapy. Nevertheless of their values, they have not been found useful in determining the primary problem because of the extensive overlap of their ranges between cases with different causes and should be used to augment other clinical findings to be most useful in accurately predicting the prognosis for horse with colic. Based on the previously mentioned results, it is recommended that horses with colic should be subjected to blood gas analysis and anion gap calculation adjunct to clinical examination in order to facilitate making the correct decision. |
