The objective of the study was to point out several significant changes in haematological values of male poultry occurring during sexual maturation and development of spermiogenesis using chickens as a model species. The investigations were carried out in a set of 50 clinically normal breeding cockerels of the paternal line RIR-05 and covered the age span of 10 through 35 weeks. Blood samples collected at 5-week intervals from vena basilica were tested for total erythrocyte count, packed cell volume, haemoglobin content, mean corpuscular haemoglobin concentration, mean corpuscular haemoglobin content, mean erythrocytic volume, and total leukocyte, basophil, eosinophil, neutrophil, lymphocyte and monocyte counts. The paper provides new comprehensive information on haematological changes occurring during sexual maturation of male breeding chickens up to the onset of reproductive activity.
