COMPARISON OF BIOCHEMICAL AND HEMATOLOGICAL PARAMETERS IN TWO DIFFERENT BREEDS OF HORSES (ARABIAN AND BARBE) IN ALGERIA

Specific reference values (in range) are needed for each animal species for the appropriate interpretation of the results obtained from serum biochemical and haematological tests. The aim of this study was to determine ranges of Haematological and Biochemical parameters of pure-bred Arabian and Barbe mares to evaluate the need for defining reference values for different breed groups.

20 clinically healthy mares from one farm (Chaouchaoua HARAS-Tiaret. Algeria) were divided into two groups. Groups 1 and 2 comprised 10 Arabian Mares and 10 Barbe Mares (age from 04 to 09 years). Glucose, urea, albumin, aspartate aminotransferase (AST), Gamma Transferase (GT), Creatinine phospho kinase (CPK), Sodium (Na), Potassium (K) concentrations were measured in the blood serum samples.

Haematological profile were determined, red blood cell parameters (MCV, MCH, MCHC), number of leucocytes and the percentage of their respective platelets kinds, There were significant Breed related differences for most of the biochemical and Haematological parameters, (Potassium)P= 0.006*,(urea)P= 0.000***, (GGT), (Albumin) P= 0.043*, P= 0.041*, except for: AST, CPK, RBC, Hb, Fibrinogen.

The results of the present study indicate that there is variation in the values of most of the biochemical and haematological indices of Arabian and Barbe mares in Algeria. ((Haematocrit %) P= 0.031 * (VCM um3) P= 0.022 * (MCHC g/dl) P= 0.027 * Leucocytes P= 0.01 *(poly éosi mm3) P= 0.000*** (poly baso mm3 ) P= 0.037 *(Lympho mm3 ) P= 0.001 ** (Platelets M/mm3 ) P= 0.012 *.

The breed influences some of the resting haematological and biochemical indices in adult Mares. Barbe Mares used for reproduction have higher performances capacity and show a more beneficial adaptation for the Algerian environment compared to Pure Arabian Mares used for reproduction.
