ABSTRACT The aim of this study was to investigate that annual change of haematological parameters in Angora goat. Thirteen goats (six female and seven male aged 1.5 years at the beginning of the experiment) were used in this study. For this purpose, to determine haematological parameters, blood samples were taken from jugular vein of each goat in every month for one year. Red blood cells (RBC), mean corpuscular volume (MCV), haematocrit (Hct), haemoglobin (Hb), mean corpuscular haemoglobin concentration (MCHC), mean corpuscular haemoglobin (MCH), red cell distribution width (RDW), white blood cell (WBC), lymphocytes (Lym), granulocyte (Gra), monocyte (Mon), thrombocytes (THR), mean platelet volume (MPV), plateletcrit (Pct) and platelet distribution width (PDW) were analysed by haematology analyser. The data obtained were analysed using two-way repeated measures analysis of variance (ANOVA). As a result of statistical analysis, gender x month interactions were statistically different (P < 0.01) for RBC, MCV, Hb, Mon, THR, MPV and Pct, while significant differences (P < 0.01) were found among the months for Hct, MCH, MCHC, RDW, WBC, Lym, Gra and PDW. As a result of this study, it was determined that seasonal changes, different physiological periods and environmental stress that occurred during experimental periods had significant effect on the annual pattern of erythrocyte, leukocyte and thrombocytes of Angora goats.
