    Sex comparism of white Fulani cattle blood profile in Southwestern Nigeria
    (Animal Science Association of Nigeria, 2013) Ladokun, A. O.; Oyebode, O. A.; Abiona, J. A.; Ososanya, T. O.
    Sexual dimorphism has been established in the brain regions of farm animals and poultry, but for their blood, reports do not agree as to differences at the same age. While some reports show no differences except for pregnant and lactating females, others indicate Otherwise. This study was carried out to investigate the blood of white Fulani breed of cattle in southwestern Nigeria if there could be differences at same mature age (4yr). A total of 100 cattle were used consisting of 50 bulls and 50 cows. Full haematology was investigated using the Vet AutoHaemoanalyser machine. Some serum metabolites were also investigated including total Protein, Albumin and total cholesterol. Data obtained were subjected to one-way analysis of variance (ANOVA). The results show that white blood cell count (WBC) was significantly (P<0.05) higher in females (17.23±1.08) than in males (12.25±0.77). Mean Corpuscular haemoglobin concentration (MCHC) also showed sex differences with females having higher and significant (P<0.05) average value (33.8±0.19) than males (32.6±0.24). The results from Serum analysis show that bulls (with 37.8±0.54) have higher and significant (P<0.05) Albumin values than cows (34.9±0.29). Though the results obtained in this study fall within normal ranges for this species, it however does not indicate any specific sex effect for this breed.

    Haematological evaluation of pregnant ewes fed broiler-litter based diets
    (2010) Ososanya, T. O.
    Blood is a transport medium for the body which plays an active role in sustainability and survival of the organism. Haematological indices reflect the effect of dietary treatments on the animal especially the type and amount of feed ingested and available for the animal to meet its body requirements. A study was carried out for 10 weeks to assess changes in some haematological indices with advancing pregnancy in ewes fed Broiler Litter (BL) based rations. Blood samples were collected at each trimester of pregnancy and analyzed for Packed Cell Volume (PCV), Red Blood Cell (RBC), White Blood Cell (WBC) counts and Haemoglobin (Hb) concentration. Other parameters estimated were: Mean Corpuscular Value (MCV) and Mean Corpuscular Haemoglobin Concentration (MCHC). Results showed that in the first trimester, PCV and Hb. values were significantly higher (P<0.05) in animals fed at 0%, 25%, 50% and 75% BL inclusion levels. In the second trimester, RBC values decreased with increasing levels of BL in the diet while other parameters studied were not significantly different. The findings of this study showed that livestock farmers in the tropics can include broiler litter as feed supplement up to 25% without any adverse effect on the blood chemistry.
