Impact of Collared Dove Pigeons (Streptopelia decaocto) Age on some Hematological and Biochemical Parameters in Mosul City

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.
