伊犁马长途运输应激血液生理、生化及激素指标的动态变化规律

为了解伊犁马经长途运输过程中的血液生理生化指标的动态变化规律,本试验选用6匹雄性伊犁马,进行路程400 km,历时480 min的长途运输,并分别于上车运输前、中、后等8个时间点采集颈静脉血进行血液指标的检测.结果显示:与上车前相比,在运输4h时马血液中红细胞总数(RBC)、淋巴细胞比率(LYM％)显著下降(P＜0.0...

The Dynamic Changes of Blood Physiology,Biochemistry and Hormone Indexes of Ili Horse Under Long-distance Transport Stress

The purpose is to explore the dynamic changes of blood physiological and biochemical indexes during the long-distance transportation of Ili horse. In this experiment, 6 male Ili horses were selected for transportation of 400 km lasting for 480 min. And jugular venous blood was collected for blood index detection at 8 time points (including before transportation, during transportation, and after transportation). The results showed that the total number of red blood cells (RBC) and the ratio of lymphocytes (LYM%) in horse blood decreased significantly (P<0.05), while the granulocyte (GRAN) and granulocyte ratio (GRAN%) increased significantly (P<0.05) after the horses were transported for 4 hours. After 6 hours of transportation, Triiodothyronine (T3), Tetraiodothyronine (T4), Growth Hormone (GH), Cortisol (COR), Albumin (ALD), Cholesterol (CHOL) all increased significantly (P<0.05), and Hematocrit (HCT) and Urea (UREA) decreased significantly (P<0.01). Long-distance transportation can change the blood indexes of horse and make them first increase and then decrease. The change peak mainly occurs at the 6^th hour of transportation. The above indicators can be used as the key to determine whether the horse has transportation stress.
