Abstract   

Twenty horses suffering from colic were studied for clinical observations and changes in serum electrolytes (Na, K, HCO3, Cl) and PCV. Colic was confirnied by the rectal palpation. The rectal temperature, heart rate and respiration rates showed a significant increase in colic group. En the serum electrolytes, i.e.. Na, and K difference was non-significant, while FICO3 and Cl showed significant decrease with control. Their values were 127.85. 4.25. 87.85 and 30.97 inEq/L respectively for this group. The average PCV recorded was 36.05% with non-significant difference between the colic and control horses.
