| Popis: | The aim of this study was to determine the basic haematological parameters in feral and racing pigeons and to compare these parameters according to age, sex and season in healthy feral pigeons as well as between Chlamydophila-serologically positive and negative feral pigeons. Red blood cells (RBC), packed cell volume (PCV), haemoglobin (Hb), mean cell volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), white blood count (WBC), thrombocyte count and differential WBC, were determined in 366 pigeons (Columba livia forma domestica) captured in the City of Zagreb between 1999 and 2002. Of these, 232 feral (179 adult and 53 juvenile, 104 male and 75 female) and 57 racing pigeons (25 male and 32 female) were clinically healthy and bacteriologically and serologically negative, but 77 birds had antibody titres against Chlamydophila sp. Significantly lower values of RBC, PCV, Hb, MCH, WBC and thrombocyte (P |
