Outline
This study aimed to explore the effects of gender， age， and altitude on the hematological and blood rheology parameters of Bamei cattle， providing a basis for further understanding of the physiological adaptation mechanisms of Bamei cattle in different environments. A total of 166 healthy Bamei cattle from different altitudes in Nyingchi were selected， and 21 hematological and 13 blood rheological parameters were measured. Descriptive statistics， correlation analysis between parameters， and variance analysis based on factors such as gender， age， and altitude were performed. The results indicated that all hematological parameters of Bamei cattle were within the reference range， showing that their blood physiological indicators were in a normal state. The further variance analysis showed that gender， age， and altitude significantly affected the blood physiological indicators. Female cattle had significantly higher red blood cell volume and platelet activity indicators than male cattle （P<0.05）. Juvenile cattle showed significantly higher lymphocyte counts and platelet numbers， as well as other immune and hematopoietic activity indicators， compared to adult cattle （P<0.05）， indicating that gender and age influence blood composition and rheological performance. The effect of altitude was particularly significant. As altitude increased， oxygen-carrying indicators such as red blood cell count （RBC）， hemoglobin （HGB）， and hematocrit （HCT） significantly increased （P<0.05）， demonstrating a typical high-altitude hematopoietic adaptation trend. At the same time， plasma viscosity， aggregation indices， and whole blood flow resistance all significantly increased （P<0.05）， suggesting that blood became more viscous and less fluid in the high-altitude environment. Further correlation analysis revealed significant positive correlations between various internal indicators of the hematological and blood rheology systems. For example， in the red blood cell system， HGB was highly correlated with HCT， and mean corpuscular volume （MCV） with mean corpuscular hemoglobin （MCH）， with correlation coefficients reaching 0.98. In blood rheology， plasma viscosity and fibrinogen were strongly correlated with erythrocyte viscosity， with a correlation coefficient of 1.00. These correlation results revealed the intrinsic interconnection and mutual influence between the blood physiological indicators of Bamei cattle. The results of this study indicate that Bamei cattle possess the ability to adapt to the hypoxic environment of the plateau through enhanced erythropoiesis and the regulation of blood rheological properties. This provides important physiological evidence for a deeper understanding of the hypoxic adaptation mechanisms in plateau livestock.
