The ontogenic development of pancreatic juice amylase was studied in 12 Surti buffalo calves from birth to early ruminant stage (15 wk). The pancreatic juice was collected by cannulating the pancreatic duct. The samples were obtained 30 min before feeding (BF) and 30 min after feeding (AF) both during morning and evening hours. The results revealed significant age effect on amylase, except BF at morning hours. The activity was found to gradually increase with age up to 15 wk. The pattern remained the same when activity was expressed in volume of pancreatic juice secreted. Overall diurnal variations were not significant, however, it was found to significantly increase on 0 d, 3 wk (P0.05) and decrease on 14 wk (P0.05) at evening hours. Overall postprandial levels were found to increase due to feeding up to the extent of 66.17 percent (+47.34 SU/dl) as compared to fasting values (71.54 plus or minus 2.31 SU/dl). Average amylase level (SU/dl) gradually increased from colostrum feeding (32.72 plus or minus 2.64) to MRP (55.70 plus or minus 3.61) and then at inclusion of concentrate and hay (109.41 plus or minus 7.33) and at feeding dry and green fodder (132.43 plus or minus 7.51). The results suggested that amylase level at the time of liquid diet feeding was lower and found to increase with the inclusion of solids in the diets
