Most regions in Iran are generally selenium (Se) deficient and all mineral premixes which used in farm animals contain Se in the form of sodium selenite. The objective of this study was to evaluate the effects of injected Se and vitamin E (vit E) on hematology, serum proteins, and performance of lambs during the period which the animals are at risk of Se and/or vit E deficiency. The study also aims to determine the relationship between selenium injection and the levels of other trace elements in blood serum of lambs. A total of 16 lambs of Baloochi breed (age, 70±7 days and weight, 15.2±1.4) were enrolled in the study. The animals were divided into two groups. In the test group, vit E and Se injected at a dose of 0.2 ml/kg BW (Vetoquinol, Selepherol®, Lure Cedex, France, α-tocopherol acetate 3.82 g/100 ml plus sodium selenite 0.023 g/100 ml) at the enrollment. Control lambs were received equal amounts of normal saline as placebo. Blood was sampled from the jugular vein at the beginning of the study (enrollment, before injection of vit E and selenium and saline) and at days 7, 14, 21, and 28 of experiment. The amounts of total serum protein, albumin, glucose, iron, copper, zinc, creatine kinase (CK), and aspartate aminotransferase (AST) and Se were measured. The concentration of globulin was calculated as the difference between total serum protein and albumin. For evaluation of growth and health, body weight of all the lambs was measured at day 0 of the experiment and the sampling times and days of treatment for each lamb were recorded. Treatment with Se and vit E decreased the activities of CK and ASTcompared to the controls (p<0.05). Age (sampling time) had significant effects on the values of Se, iron, zinc, AST, hemoglobin, total protein, glucose, weight, height, and length (p<0.05). Significant interactions between sampling time and group were seen for CK, AST, iron, glucose, weight, and length. No significant differences were seen for total weight gain (control, 3.48± 0.75 kg; test, 3.85±0.9 kg), and average daily gain (control, 0.12±0.03 kg; test, 0.14±0.03 kg) between trial groups.
