Abstract


Our study evaluates the effects of the changing of conditions of exploitations of draft horses, over some blood parameters. In this purpose were monitored 6 adult draft horses. Until the start of the experiment the horses were kept in home hibernal manure (800 m altitude). In spring the horses were transferred in the logging area. The tested parameters were evaluated four times. First (1st), evaluation was made immediately before the transfer of horses. The second evaluation (2nd) was made as soon as the horses arrived at the logging area (1000 m altitude). The third evaluation (3rd) was made after a week of intense work in logging area. The fourth evaluation (4th) was made after three weeks of intense work. Every evaluation blood samples were collected. RBC count, WBC count and N/L ratio were performed. The RBC values were significantly increased (P < 0.05) in 2nd(12.29 %), 3rd(7.66 %) and 4th(6.66 %) evaluations compared to 1st evaluation. This polycythemia represents an adaptive response to transport, hard work stress and altitude hypoxia. The WBC values were significantly increased (P < 0.05) in 2nd(28.5 %), 3rd(16.66 %) and 4th(14.52 %) evaluations compared to 1st evaluation. This leukocytosis seems to be an adaptive response to transportation and hard work stress. The N/L ration were significantly increased (P < 0.05) in 2nd(57.59 %), 3rd(51.30 %) and 4th(24.52 %) evaluations compared to 1st evaluation. According to these results, the horse transportation and logging work seems to be very stressful factors.
