Change of Blood Gas Index in Venous Blood in Different Stages of the Yili Horse 1000 m Trot Training

Blood gas index in venous blood of 12 Yili horses in different stages of 1000 mtrot training(motionless,after the warming up,after the game instantly,15 min,30min,60min)were detected by i-STAT blood gas analyzer,and the differences and correlation of the blood gas index were analyzed.The results showed that before and after exercise PvCO2,PvO2,HCO3,TCO2,SvO2 and Glu of the venous blood did not change significantly(P0.05).Blood pH,BE and Ca2+were lower immediately after the game,but after 15 min rest basic rebounded to motionless level.K+,Hct and Hb immediately after the game were significantly increased(P0.05),but after 15 min rest basic back down to motionless levels.Blood pH value was highly significant positive correlation with BE and HCO3(P0.01),and significantly positive correlation with the TCO2concentration(P0.05),Hct,Hb were highly significant negative correlation with pH,HCO3(P0.01),Hct,Hb were highly significant positive correlation with K+(P0.01).The analysis showed that BE,HCO3,TCO2,Hct and Hb on acid-base balance all had certain adjustment,Na+,K+and Ca2+on the body movement had certain adjustment.
