Abstract
In order to study the effect of exercise on the physiological norms of the horses, six horses belonging to the I (K) Mounted Squadron N.C.C. of Kerala Agricultural University were divided at random into groups of three animals. First was subjected to an exercise regime in the first month while the other remained as control. Groups were switched over every month.
The parameters studied were body temperature, respiratory rate, heart beat, red blood cell count, packed cell volume, erythrocyte sedimentation rate, glucose and lactic acid, before exercise, after exercise and after one and half hours of rest. The results obtained are tabulated.

________________________________________________________________
Exercise significantly changes all the physiological parameters except body temperature which was kept fairly constant by horses. Ambient temperature and relative humidity were found to cause stress in the horses. Parameters like respiratory rate and heart beat were considerably increased after exercise to keep the body temperature fairly constant in horses.
In spite of one and half hours of rest the body temperature, respiratory rate, heart beat, red blood cell count, erythrocyte sedimentation rate and glucose content could not reach the normal level.
However the lactic acid level and packed cell volume could be brought back to the normal level after one and half hours of rest.
Age and stages of conditioning of horses were found to influence the level of physiological parameters and time needed to bring them back to the normal level.
