Abstract

A series of experiments were conducted to determine the basic physiological parameters, their diurnal changes and response to exercise in exotic horses reared in Sri Lanka. Thirty two healthy horses (9 Thoroughbreds and 23 Selle Fransiasis) of the Sri Lanka Police Mounted Division at Colombo, Kandy and Nuwara Eliya were used for the study. Heart Rate (HR), Respiratory Rate (RR) and Rectal Temperature (RT) of individual horses at resting stage (T0) at three locations were obtained at hourly intervals during 24-hour periods. Environmental Temperature (ET) and Relative Humidity (RH) were measured simultaneously. Individual RT, HR and RR were measured for 21 days, just after completing the following continuous exercise regime (T1 to T4) or traffic duty (T5): T1:0800-8010 hwalking (speed 100 m/min); T2:0812-0822 h-trotting (speed 250 m/min); T3:0824-0834 hcantering (speed 350 m/min); T4:0836-0900 h-parading(100 m/min) and T5: 0800-0930 htraffic duty. Horses were stabled after exercise/traffic duty and bathed from 1030-1100 h. RT, HR and RR were measured at 1000 h and 1100 h on stabling (T6) and bathing (T7). Data were analyzed using correlation, regression and GLM procedures. Overall mean±SD values of resting RT, RR and HR were 101.0±1.3 °F, 30.3±23.5 and 35.6±8.6 beats/min, respectively. Resting RT, RR and HR varied diurnally, signifying that ET>75 °F were thermally challenging. The RT, RR and HR increased (p<0.05) with increasing exercise intensity. Cantering and traffic duty had the most profound effects. Stabling and bathing lowered (p<0.05) RT, RR and HR, but not to pre-exercise levels. Close monitoring of physiological indices in horses is necessary during cantering and traffic duty at ET>75 °F.
