Hasak ve Hasmer Melez Koyun Irklarına Ait Bazı Hematolojik ve Biyokimyasal Parametreler

The  aim  of  this  study  was  to  determine  the  reference  values  of  haematological  and  biochemical  parameters  in  Hasak  and  Hasmer  crossbred  sheep,  covering  different  age  ranges.  In  this  context,  a  total  of  120  blood  samples  from  Hasak  (n=60)  and  Hasmer  (n=60)  breed  were  collected  from  clinically  healthy  young  (6  months)  and  adult  (1-­‐3  years  old)  sheep.  The  blood  samples  were  analysed  for  white  blood  cells  (WBC),  lymphocytes  (LYM),  monocytes  (MON),  granulocytes  (GRA),  red blood cells (RBC), haemoglobin (Hb), packed cell volume (PCV), mean corpuscular volume (MCV), mean corpuscular  haemoglobin  (MCH),  and  mean  corpuscular  haemoglobin  concentration  (MCHC).  In  the  serum,  alanine  aminotransferase  (ALT), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT)  enzyme activities,  urea,  creatinine,  albumin,  glucose,  total  protein,  and  total  cholesterol  levels  were  observed.  In  both  breeds,  the  LYM  count,  AST,  GGT  activities  and  glucose  level  were lower, while MCV, MCH and total cholesterol levels were higher in adult than  those in young sheep.  However,  depending  on  the  age,  no  statistically  significant  difference  was  observed  in  the  rest  of  the  haematological  and  biochemical  parameters.  Consequently,  the  data  obtained  from  this  study  could  be  accepted  as  reference  blood  values  for  Hasak  and  Hasmer  crossbred  sheep.
