The Influence of Walking Stress on Some Blood Parameters in Desert Goats

Abstract

This study was conducted to investigate the changes on blood parameters due to walking stress and the response of blood parametres to walking stress in correlation with sex and season in 21 desert goats, which were allocated randomly into test group (6bucks, 6 does), control group (5 bucks, 4 does), and transported in two experiments (Experiment one in winter and experiment two in summer) in the year 2011, up to 12 km round trip for 7hrs, every experiment was replicated three times with one week interval. Blood samples was taken before transport, at 7hrs transport and 24 hrs rests, in the same time interval blood was collected from control group. Blood samples were assessed for; RBCs count, hemoglobin concentration, PCV, MCV, MCH, MCHC, serum glucose, total leukocytes and differentials count. Hb concentration, increased (P<0.05) at 7hrs transport in the experiment one, PCV, MCV values decrease (P,0.05) and serum glucose concentration increase (P<0.05) at 7hrs transport in the experiment two ,neutrophils percentage, N:L ratio were increase (p<0.05), lymphocytes percentage decrease (p<0.05) at 7hrs transport in both experiments, while eosinophils, monocytes percentages were increased (P<0.05) at 7hrs transport in the experiment one , and eosinophils percentage decrease(p<0.05) at 7hrs transport in the experiment two. However RBCS, MCH, MCHC values were not show any significant change in both experiment. Sex did not have any significant effect on the response of blood parameters to walking stress in this study, while in the case of the influences of seasons on the response of blood parameters to the walking stress show significant (P<0.05)effects included; decrease of Hb, MCH ,MCHC and lymphocytes percentage, an increase of neutrophils percentage and serum glucose concentration at 7hrs walking stress in summer, increase of eosinophils and monocytes percentages at 7hrs walking stress in winter. However RBC,PCV, IV MCV and total WBCs count were not influenced. It is conclude that walking stress of desert goats in this study induce increase in neutrophils, N:L ratio, decrease in lymphocytes, while sex did not influence the response of blood parameters to walking stress. On the other hand the influence of season on the response of blood parameters to twalking stress induced; eosinophlia, monocytosis, increase in Hb concentration, MCH and MCHC in winter, while induce eosinopenia, increase in glucose concentration in summer, and the changes in neutrophils and lymphocytes percentage in summer were more than those in winter.
