Abstract

The purpose of this experiment was to study the adaptive changes of erythropoietin (EPO) gene expression and blood physiological and biochemical indexes in the blood of Hu sheep after entering high-altitude area in Qinghai. Ninety 8-month-old Hu sheep reserve ewes with 8-month-old and similar body weight [(32.11±1.86) kg] in mid-altitude area (Gansu province, 1 500 m) and high-altitude area (Qinghai province, 3 200 m) were selected, respectively. The Hu sheep in that two places were randomly divided into 3 groups with 30 sheep in each group, respectively. The EPO gene expression and blood physiological and biochemical indexes of Hu sheep in different altitude areas were measured. The result showed that the relative expression level of EPO gene in blood of Hu sheep in the high-altitude area was higher than that of Hu sheep in the mid-altitude area (P<0.05); the blood red blood cell count (RBC), hemoglobin concentration (HGB), hematocrit (HCT) and mean corpuscular volume (MCV) of Hu sheep in the high-altitude area were respectively increased by 36.23%, 45.94%, 58.34% and 23.65% (P<0.05), and the white blood cell count (WBC), mean erythrocyte hemoglobin concentration (MCHC), platelet count (PLT) and mean platelet volume (MPV) were respectively reduced by 27.33%, 11.68%, 18.27% and 6.20% (P<0.05) compared with the mid-altitude area. The activities of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and the content of glucose (Glu) of Hu sheep in the high-altitude area were respectively increased by 10.71%, 16.80% and 62.72% (P<0.05), and the serum total cholesterol (TC) content was reduced by 33.22% compared with the middle-altitude area (P<0.05); the activities of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), total antioxidant capacity (T-AOC) and the content of malondialdehyde (MDA) in serum of Hu sheep in the high-altitude area were 5.99, 2.35, 4.10, 1.49 times higher than those of Hu sheep in the mid-altitude area (P<0.05), respectively. In summary, Hu sheep raised in the high-altitude area of Qinghai show adaptive changes in the blood EPO gene expression, blood physiological and biochemical indexes, indicating that Hu sheep have the potential to adapt to high-altitude environment.
