Abstract
Normal reference ranges for hematology, blood chemistry, platelet indices and coagulation parameters were determined in male and female Erlanger's gazelles (Gazella erlangeri). Data investigated included complete blood count, Platelet count (PLT), plateletcrit, mean platelet volume, platelet distribution width and a wide range of biochemical and chemical parameters including serum proteins, enzymes and other clinically important metabolites and inorganic constituents. Normal ranges of coagulation parameters were also investigated, namely; Prothrombin Time (PT), Activated Partial Thromboplastin Time (APTT), fibrinogen, procovertin, antihemophilic factor A coagulation activity, plasma thromboplastin component, Stuart factor and plasma thromboplastin antecedent concentration. Statistical analysis showed significantly higher (p<0.05) total leucocyte and lymphocyte counts in female as compared to male gazelles. All other haematological parameters were similar in males and females. No significant intersex differences were found in mean platelet counts, platelet indices and coagulation parameters. As in other desert gazelles, decreased PT and APTT and increased PLT, fibrinogen and antihemophilic factor coagulation activity were recorded in Erlanger's gazelle as compared to humans. Serum chemical analysis revealed significantly higher (p<0.05) concentrations of glucose, urea, BUN and total bilirubin and significantly lower total protein and CL concentration (p<0.05) in female versus male gazelles. Other chemical parameters were similar in the two sexes. All the data recorded in this study are reported for the lit time in Erlanger's gazelles.
