Abstract:

This study was designed to compare the myocardial enzymes activity,liver metabolism,kidney metabolism and some other biochemical indicators related to body antioxidant capacity,energy metabolism and lipid metabolism between yaks at two different altitudes.49 blood samples of yaks were collected in Datong,Qinghai (higher altitude) and 29 blood samples of yaks were collected in Hongsongwa farm,Hebei (lower altitude).25 blood biochemical indicators were tested and the results of the two groups were compared with independent t-tests.The results showed that,compared with yaks at lower altitude,the activities of blood ALT,AST,CK-MB,α-HBDH and LDH,the levels of blood TBiL,DBiL,TP,GLB,CRE,UA,MDA,and GLU in yaks at higher altitude were extremely significantly higher (P<0.01),and the activity of ALP were significantly higher (P<0.05) as well.While the SOD activity,NO,ALB and TG levels,and A/G were extremely significantly decreased (P<0.01).The rest of the indicators showed no significant difference (P>0.05).In conclusion,there were certain differences in myocardial enzyme activity,metabolic function and antioxidant capacity of yaks at two different altitudes,and yaks at higher altitude had been on the plateau for a long time and gradually developed the adaptability to the plateau hypoxia environment.

Key words: yak; myocardial enzymes activity; liver metabolism; kidney metabolism; antioxidant capacity; altitude acclimatization
