Abstract:

In order to understand the blood physiological and biochemical reactions after long-distance transport, 23 Akhal-teke horses (male horse 14, mare 9, aged 2 to 6 years old), were selected and transported from Russian to Alashankou of Xinjiang (5 d road transport). 7 and 35 d after reaching the destination, the jugular vein blood were collected for the determination of physiological and biochemical indicators and stress-related hormone levels. The remote control horses without transport (15 local Akhal-teke horses,male horse 10, mare 5, aged 6 to 10 years old) were used for comparative study. The results showed that on the 7th and 35th day after transport, the number and proportion of granulocytes (Gran), hematocrit (HCT), blood platelet (PLT) and alkaline phosphatase (ALKP) were significantly or extremely significantly higher than those of the local Akhal-teke horses (P<0.05; P<0.01), while the number and percentage of intermediate cells (Mid) and the level of blood glucose (GLU) were significantly or extremely significantly decreased (P<0.05; P<0.01); On the 35th day after transport, the mean red blood cell volume (MCV), phosphorus (PHOS) and total protein (TP) were significantly or extremely signifcantly increased (P<0.05; P<0.01), and the percentage of lymphocytes (LY) was significantly decreased (P<0.05); On the 7th day after transport, the levels of antidiuretic hormone (ADH), growth hormone (GH), UREA and insulin (INS) were significantly or extremely signifcantly decreased (P<0.05; P<0.01), and the total bilirubin (TBIL) and triiodothyronine (T3) were signigicantly increased (P<0.05), but there was no significant difference between the two groups (P>0.05) on the 35th day after transport. Based on the above results, after the long-distance transport, there had a corresponding transient stress response in Akhal-teke horses, which required some adjustment after the recovery period (35 d) to let most of the indicators were consistent with those without long-distance transport. So the horses could not be used until they were in a normal state, in order to avoid long-term irreversible lesions.

Key words: Akhal-teke horses; long distance transportation; physiological parameter; biochemical parameter; stress-related hormone
