Abstract:

This study was designed to investigate the effects of long-distance transport stress on blood parameters of donkey.The study was conducted with 12 heads of Dezhou donkeys with weight of (140.8±5.2) kg,the transportation distance was about 950 km,the departure temperature was -20℃,and the destination temperature was -10℃,which lasted for 21 h,including 10 parking observations (≤ 20 min).15 mL of jugular venous blood was collected before loading,0 h after transportation and 3,5,7,9 and 15 d after transportation,and blood hormone indexes,blood routine indexes and blood biochemical indexes were detected,and the weights before transport,0 h after transport and 10,20 and 30 d after transport were recorded.The results showed that the concentrations of adrenocorticotropic hormone (ACTH),heat shock protein 90 (HSP90) and cortisol in the serum at 0 h after landing were significantly higher than those before transportation (P<0.05),and gradually decreased within 3,5,7,9 and 15 d after transportation,and ACTH and HSP90 recovered to pre-carriage levels.The number of neutrophils (Neu),the total number of red blood cells (RBC) and the hemoglobin concentration (HGB) increased significantly after 3,5,7,9 and 15 d (P<0.05),the total number of white blood cells (WBC) increased but not significantly different from that before transportation (P>0.05),the total number of lymphocyte (LYM) was significantly lower than before transport (P<0.05).There were no significant changes in serum total protein (TP),serum albumin (ALB),creatinine (CREA) and lactate dehydrogenase (LDH) before and after transport (P>0.05).Aspartate aminotransferase (AST),creatine kinase (CK) and urea (UREA) were significantly higher than before transport (P<0.05).The body weight decreased significantly (P<0.05),and recovered to the pre-transport level within 10 d after transportation.The above results indicated that long-distance transport induced stress response to sputum,liver damage and elevated levels of metabolism,but the immune system was not significantly damaged.Within 15 d after landing,the body gradually recovered from the stress response to the pre-shipment state.
