Abstract
Experiments were performed to investigate the effect of ascorbic acid (AA) in reducing hemato-biochemical changes in pack
donkeys during the cold-dry (harmattan) season. Six experimental donkeys administered orally AA (200 mg/kg) and six control donkeys not
administered ascorbic acid were subjected to packing. Blood samples were collected from all donkeys for hematological and biochemical
analyses. In the control donkeys, packed cell volume (PCV), erythrocyte count and hemoglobin concentration (Hb) decreased significantly
(P<0.05) at the end of packing. In the experimental donkeys, there was no significant difference between the pre- and post-packing values of
PCV, erythrocyte count and Hb. In the control donkeys, the neutrophil and neutrophil:lymphocyte ratio increased significantly (P<0.05) post
packing, but in the experimental donkeys, the pre- and post-packing values were not significantly different. The eosinophil count increased
significantly (P<0.05) in experimental and control donkeys post packing. In conclusion, packing exerted significant adverse effects on
the hematological parameters ameliorated by AA administration. AA may modulate neutrophilia and induce a considerable alteration of
erythroid markers in donkeys subjected to packing during the harmattan season.
