Abstract: Six adult Marwari does were exposed to solar radiation during summer when minimum and maximum ambient temperature were 30.5 and 40.0 grade C respectively. Skin surface temperature and physiological responses (respiration rate, rectal temperature, heart rate) were studied. The respiratory activity increased more than twice and body temperature increased by 1 to 2 grade C depending on coat color of doe. The highest surface temperature observed was 57.4 grade C at rump and doe increased RT only by 1 grade C above preexposure RT of 38.5 grade C. At this temperature does started panting. As the ambient temperature increased, the effects on respiration were noticeable and pulmonary activity increased 2 to 3 folds and animals started panting. The diurnal changes and temperature gradients indicate that goats are able to tolerate thermal stress during summer day. During summer when both ambient temperature and solar radiation intensity increase, goats exhibit thermal distress and start panting. The changes in surface temperature at different skin sites varies in relation to solar exposure, skin coat cover and colour of hairs. The extremities remain at low temperature and help in heat dissipation through vasodilatation process. The panting limitedly help in heat loss process in goats. |
