| Abstract | ||||
| A significant increase, occurred in blood selenium level, 3 hours after selenium I/M administration, and reached its highest level 24 hours later. Then began to decline gradually and reached to nearly its preinjection level one week after administration. Similar pattern occurred in blood selenium level in the first 2 hours after E-selenium I/M administration but its level raised gradually to its highest peak, one week after administration. Studding effect of selenium and E- selenium administration on selenium levels at long intervals when given by I/M route indirectly to pregnant buffaloes and directly to calves, revealed that its level behave similarly as when studied at short intervals. Although calves from selenium treated days were born with significantly very high blood selenium level, this level decline gradually with progression of age and approached that of control calves, 75 days of age. Gradual increase in its level occurred in selenium treated calves but decline to below that of control group, at a similar age. On the other hand, and dis similar, calves from E-selenium treated dams were born with relatively high blood selenium level, gradual) increase occurred in its level with pronounced elevation on its level at 75 days of age. Similar behavior occurred in E-selenium treated calves. | ||||
