中国西门塔尔牛血液生理生化指标分析OA

This study utilized fully automated hematology and biochemical analyzers to measure and analyze 21 hematological in-dices and 16 biochemical indices in 40 eighteen-month-old Chinese simental cattle(20 males and 20 females)collected from Yun-nan province.The results showed that compared to female cattle,in hematological parameters,male cattle exhibited very highly sig-nificant elevations in red blood cell count,hemoglobin,and hematocrit(P<0.01),while female cattle displayed a significantly higher eosinophil count(P<0.05).17 other hematological indices,such as white blood cell count etc.,showed no significant sex-based differences(P>0.05)between male and female cattle.Regarding biochemical parameters,male cattle demonstrated very significantly higher levels of creatinine and albumin-to-globulin ratio(P<0.01),while female cattle exhibited a very significantly elevated urea-to-creatinine ratio(P<0.01).Additionally,male cattle showed higher alanine aminotransferase levels and calcium levels(P<0.05),while female cattle had higher total protein and globulin concentrations(P<0.05).9 biochemical indices,such as urea etc.,showed no significant sex-related variations(P>0.05).Compared with eight other cattle breeds,female Chinese simental cattle had the highest eosinophil count,meanwhile male Chinese simental cattle had the highest red blood cell counts.Both male and female Chinese simental cattle had the highest hemoglobin and hematocrit levels,suggesting their advanced oxygen-binding,storage,transport,and release capacities.Biochemically,Chinese simental cattle exhibited the highest glucose,aspartate amino-transferase,creatinine,and globulin levels,whereas male Chinese simental cattle had the highest albumin-to-globulin ratio.In con-clusion,Chinese simental cattle demonstrated strong oxygen transport capacity and immune characteristics.
