Hematological profile of Colombian creole donkey (Equus asinus)

Abstract

The diagnosis of diseases in animals depends to a large extent on clinical examinations and laboratory results, in which biological variations are reflected. The hematological values are very important for the evaluation of the normal physiological state of an animal. However, very few works have been carried out in this respect on creole asses. The objective of this investigation was to determine the mean values of a hemogram for creoles donkeys of the Colombian lowland. A cross - sectional descriptive study was performed with a non - probabilistic sample for convenience. Samples of 85 male donkeys between 4 and 15 years old were clinically healthy and fed with Brachiaria humidicula pastures. These parameters were obtained by means of a hematological analyzer (ABX Micros ESV 60). The values obtained were: leukocytes 7.6±1.6 x103/mm3, lymphocytes 39.69±10.87%, monocytes 5.89±1.63%, granulocytes 54.41±10.75%, eosinophils 7.08±2.77%, erythrocytes 4.48±0.85 x106/mm3, hemoglobin 8.62±1.3 g/dL, hematocrit 30.24 ± 5.1%, mean corpuscular volume 67.71±5.91 μm3, mean corpuscular hemoglobin 19.45±1.94 pg, mean corpuscular hemoglobin concentration 28.48±1.36 g/dL and platelets 354.20±136.24 x103/mm3. The results confirm that there are differences between the values in most hematological parameters of creole donkeys compared to those of other breeds and horses. These results may be useful in the veterinary clinical routine for the diagnosis, monitoring and control of diseases.
