Twenty four Buffalo calf were taken after colostrum feeding (6calf in each group) with the objective of Studies on the effect of different shade materials on the performance of buffalo calves. The whole year was divided in to three seasons according to the ambient temperature and relative humidity: viz winter, summer and rainy. There are four type of roofing material was used like Asbestos roof (T1), Pre painted CGI Sheet roof (T2), Thatch with polythene shading roof (T3), Galvanized iron sheet roof (T4)- four inch thick layer of paddy straw fixed to bamboo frame. The following parameter was studied. Temperature, Relative humidity (RH), Temperature Humidity Index (THI), Surface temperature (ST) of roof, , Body measurement (body height, body length, heart girth and pouch girth), Physiological Variables (rectal temp and respiratory rate) Haematological, biochemical and serum enzymatic estimation and some behaviour like, feeding, watering, rumination, near water tub, resting, standing, sleeping, resting , moving , grooming, licking, cross licking) were studied. newline
