Abstract

Abstract:

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.

Key words: horse, long-distance transport, stress, blood index, law of dynamic change
