The effects of age and gender on blood parameters in Arabian horses

Bu çalışmada, Türkiye’de yetiştirilen Arap atlarına ait hematolojik parametrelerin yaş ve cinsiyetle ilişkili farklılıklarının belirlenmesi amaçlanmıştır. Çalışma 12 kısrak, 10 aygır, 5-6 aylık 90 tay ve bir yaşlı 35 tay üzerinde gerçekleştirilmiştir. Ortalama alyuvar ve akyuvar sayıları kısrak ve aygırlarda normal, altı aylık ve bir yaşlı Arap taylarında düşük bulunmuştur. Hemoglobin ve hematokrit değerleri, kısrak ve aygırlar ile bir yaşlı taylarda normal sınırlara, altı aylık taylarda düşük olarak tespit edilmiştir. Bir yaşlı taylarda (P

The aim of the present study was to investigate the differences related to age ad gender in some blood parameters of Arabian horses bred in Turkey. In this study, 12 mares, 10 stallions, 90 foals (5 to 6 months old), and 35 yearlings were used. it was indicated that total erythrocyte count (RBC) and leukocyte count (WBC) was in normal ranges for mares and stallions while RBC and WBC values were lower for Arabian foals and yearlings. Haemoglobin (Hb) and haematocrit (PCV) were in normal ranges for mares, stallions and yearlings while it was lowest for foals. There was also a significant difference between males and females for PCV values of yearlings (P<0.05) and adult groups (P<0.01). Mean corpuscular haemoglobin (MCH) was highest in stallions (P<0.01) and lowest in female foals (P<0.05) within the gender groups. Mean corpuscular haemoglobin concentration (MCHC) was highest in male foals. Mean cell volume (MCV) was significantly lower in the young male (P<0.01) and female (P<0.001) foals compared to the older horses. Percentage of neutrophil was highest for Arabian mares(P<0.001). Percentage of lymphocyte was lowest for mares and male foals (P<0.001). Percentage of monocyte was highest for male foals and it was lowest for female yearlings (P<0.001) within gender groups. Eosinophil percentage was high in male yearlings (P<0.05). As a result of this study, it was found that blood values of Arabian horses changed due to age and gender.
