Abstract: The purpose of this study was to investigate the effects of transportation on muscle injury and oxidative stress in Ili horses.Five 24-month old Ili mares with similar body weight were selected.The transportation test was carried out after 7 days of environmental adaptation,no food or water was allowed during transportation.The total transportation distance was about 400 km and the transportation time was 8 hours.The blood samples were collected from horse jugular vein at 0 (T1),4 (T2),8 (T3) of transportation and 12 h (T4) after unloading.The serum samples were determined for related physiological and chemical indicators.The results showed that compared with T1,the muscle damage biochemical markers myoglobin (MYO) and cardiac troponin T (cTnT) increased significantly at T2(P<0.05),and increased extremely sinificantly at T3 and T4 (P<0.01).Lactic dehydrogenase(LDH) increased significantly at T3(P<0.05);The biochemical markers of inflammation C-reactive protein (CRP),interleukin-6 (IL-6) increased extremely significantly at T2,T3 and T4 (P<0.01).Cortisol(COR) increased extremely significantly at T2 and T3 (P<0.01),and increased significantly at T4 (P<0.05).Total antioxidant capacity (T-AOC),glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) decreased extremely significantly at T2,T3 and T4 (P<0.01).Catalase (CAT) decreased significantly at T3 and T4 (P<0.05).Reactive oxygen species (ROS) increased significantly at T2 and T4 (P<0.05),and increased extremely significantly at T3 (P<0.01).Malondialdehyde (MDA) increased significantly at T3 and T4 (P<0.01).Therefore,transportation could cause muscle damage and oxidative stress in Ili horses,and the adverse effects could not be eliminated within 12 h.
