A total of 24 pregnant she camels were randomly assigned into four equal experimental groups, control group not supplemented with either selenium (Se) and/or vitamin E, organic selenium group was supplemented in the diet with 3.6 mg Se/animal for 75 days, Vitamin E group was supplemented in the diet with 15 IU/kg DM of Vit. E. for 75 days, and selenium and vitamin E group was supplemented in the diet with (3.6 mg of Se/animal + 15 IU/kg DM of Vit. E for 75 days.  The supplementation was done at one month before calving at calving and one month after calving.
Blood samples were collected 4 weeks postpartum. Some blood biochemical parameters such as protein profile parameters and thyroid hormones. Oxidative stress parameters as Malondialdehyde (MDA), glutathione peroxidase (GP_X), and total antioxidant capacity (TAC) were measured. Results showed increase in protein profile parameters in all treated groups than control one. Reduce activity of MDA in all treated groups. Meanwhile, there was significant increase in both GP_X activity and TAC postpartum in all treated groups compared to the control.  A significantly increase in the concentrations of triiodothyronine hormone (T₃) in all treated groups compared to control ones.
