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.
