  An experiment was conducted to study the haematological parameters in the males and females of three indigenous Sudanese chicken ecotypes. Sixty chickens from the three different ecotypes (30 males and 30 females) were tested at mature ages ranging from 1.5-2.0 years. Total Red Blood Cells count (RBC), Packed Cell Volume (PCV), Haemoglobin concentration (Hb), total White Blood Cells (WBC), Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH) and Mean Corpuscular Haemoglobin Concentration (MCHC) were assessed. Hb, WBC, MCH and PCV were not significantly (p>0.05) different among the three different ecotypes. RBC, MCV and MCH were significantly (p<0.05) different among the three ecotypes. The haematological values of Betwil ecotype: WBC, RBC, Hb, MCH, were significantly (p<0.05) different between males and females, however PCV, MCV, MCHC were not significantly (p>0.05) different between the two sexes. The haematological values of Bare Neck: WBC, RBC, Hb, MCH were significantly (p<0.05) different between males and females, however, PCV, MCV and MCHC were not significantly (p>0.05) different between the two sexes. The haematological values of Large Beladi ecotype: WBC, RBC, PCV, Hb, MCV and MCH were significantly (p<0.05) different between males and females, however, MCHC, were not significantly (p>0.05) different between male and female.

  White Leghorn cocks (Bovans) of 2 different ages (1-2 years) were used to study the effect of age and season on semen characteristics. An average of 8 males from each age were used and kept in individual cages in an open sided poultry house for 6 months. Average maximum and minimum daily temperature during summer and autumn seasons were 40.3, 24.4 and 39.3, 26.1, respectively. Semen was collected weekly by abdominal massage and evaluated for semen volume, motility, concentration and percentage of dead and abnormal spermatozoa. There was a significant difference (p<0.05) between the two age groups in semen volume 0.22±0.02 and 0.29±0.25 mL; mass motility scores were 3.56±0.06 and 3.17±0.08 and the percentage of abnormal sperm 4.67±0.14 and 5.62±0.16% for one and 2 years, respectively. No significant difference was found in sperm concentration or percentage of dead sperms. Summer season caused a significant drop in semen volume by 8.7% in one year old and sperm concentration in two years old by 19.7%. It is also, caused an increase in percent dead sperm by 40.86 and 41.89% in 1 and 2 years, respectively.
