Abstract:
The study was established in local farm sheep in Muwafaqia / Wasit - Iraq, from
1/10/2018 until 15/1/2019, to evaluate the effect of adding selenium with or without Vitamin
E on some of the physiological characteristics of Awassi male lambs. Sixteen lambs were
selected after weaning with an average weight of (24.30) kg and aged (3-4) months. All lambs
fed 2% of body weight with a concentrated diet and randomly divided into (4) groups. Control
group (no additives), Selenium group (0.4 mg selenium), Vitamin group (100 mg vitamin E)
and combination of selenium + vitamin E group (0.4 mg selenium + 100 mg vitamin E) per kg
dietary dry matter for 90 days. At the end of the experiment, blood parameters (white blood
cell (WBC), red blood cell (RBC), packed cell volume (PCV), hemoglobin (HB), mean
concentration hemoglobin (MCH), and mean concentration hemoglobin count (MCHC) and
stress parameters were measured. The result showed selenium + vitamin E and selenium
treatments significantly increased (p <0.05) in PCV as compared with vitamin treatment and
the control group. While treatment of vitamin significantly increased (p <0.05) in hemoglobin
concentration compared to treatment of combination selenium + vitamin E. Stress parameters
such as respiratory rate and heartbeat decreased significantly (p <0.05) in treatment of
combination selenium + vitamin E compared to other treatments. There were no significant
differences between the study treatments in the WBC count.
