Abstract
The study conducted to determine the effect of differences of age on hematological and biochemical values of collared dove pigeons (Streptopelia decaocto) in Mosul city, Iraq. 28 healthy collared dove of 4 different age groups (7 birds of each group) 1 month, 3month, 6 months old as immature and 12 months old as mature pigeons were collected from local areas of Mosul city during May to August 2018. Total red blood cells (TES), packed cell volume (PCV), hemoglobin concentration (Hb), differential of white blood cells, serum total protein, cholesterol, triglycerides, uric acid and glucose were determined. The results showed fluctuations in parameters with different age groups. Mature birds had a significant increase (P ≤ 0.05) in PCV, Hb, Basophils, Monocytes, Lymphocytes, total protein and uric acid compared to immature birds. In the mature birds, there was a decrease in both heterophils, H / L ratio, total cholesterol, triglycerides and glucose when compared to immature birds. The conclusion from this study there is differences in blood parameters in collared dove pigeons according to the age advanced.
Highlights
The collared dove pigeons are a bird species that has the ability to adapt and live in different parts of the world where the construction of nests on different and high areas (Moudhafer et al, 2006)
Table (1) showed that the Total erythrocyte count (TEC), packed cell volume (PCV) and hemoglobin concentration (Hb) were significantly (P ≤ 0.05) decreased in immature pigeons compared to the mature
TEC, PCV and Hb values increased with the advancement of age, being lowest in the immature and highest in the mature pigeons
Summary
The collared dove pigeons are a bird species that has the ability to adapt and live in different parts of the world where the construction of nests on different and high areas (Moudhafer et al, 2006). The examination of blood and serology of local birds provides diagnostic information to detect the state of health and natural knowledge of the conditions that can cause a change in these values (Hauptmanova et al, 2002). Hematological value of healthy birds are affected by factors including physiological and environmental conditions, age, fasting and dietary content (Seiser et al, 2000).
