Determination of haematocrit using Mindray BC-2800Vet® automated haematology analyser and microhaematocrit method: A comparative study
A comparative cross sectional study was carried out between September and November 2014 to determine the haematocrit values obtained using automated haematology analyser and the microhaematocrit (manual) methods. A total of 197 cattle were sampled. Three (3) ml of blood was obtained from each animal into an EDTA sample bottle for analysis using both methods. The haematocrit data generated was statistically analysed by student's t-test and linear regression. The result showed a strong positive correlation (r=0.946) between the automated haematocrit and microhaematocrit values. The haematocrit values obtained by the automated haematology analyser were significantly higher than the haematocrit values obtained by microhaematocrit method (p=0.0051). The strong positive correlation probably implies that results obtained from both methods are comparable and reliable. A correction factor of the haematocrit value obtained by manual method can be obtained from the regression equation y = 1.043x + 0.5892 . This may be used to extrapolate the corrected haematocrit value for clinical and research purposes.Keywords: Cattle, Correlation, Haematocrit, Haematology analyser, Microhaematocri
Avaliação clínico-laboratorial de bovinos Nelore infectados experimentalmente com Trypanosoma vivax
Haematological values of Udah and Yankasa sheep in the northern Guinea savanna of Nigeria
Haematological values of healthy Yankasa and Udah sheep were determined to serve as baseline for clinical interpretation of haematological data from diseased local sheep. Values for Hb, PCV, RBC and WBC from the healthy flocks were similar, though lower than reported values for sheep in temperate zones except the WBC values which were higher. These parameters were lower in the infected flock and had a wider spread

Concentrations du glutathion érythrocytaire et ses corrélations avec l’hématocrite et les concentrations d’hémoglobine et d’acide ascorbique du plasma chez les bovins Wadara nigerians
Les concentrations moyennes de glutathion érythrocytaire chez les bovins zébus Wadara nigérians (n = 32) étaient de 43,9 ± 11,7 mg/dl de globules rouges ou 1,96 ± 0,57 mg/gHb. Les valeurs du glutathion érythrocytaire exprimées dans ces deux mesures ont montré une corrélation (r = 0,85) l'une envers l'autre. L'hématocrite et les concentrations d'hémoglobine sont corrélés (r = 0,59, 0,52) avec les valeurs du glutathion érythrocytaire. La répartition des fréquences a montré que 37,5 % et 90.6 % des valeurs étaient respectivement inférieures aux 40 et 60 mg/dl de globules rouges. La concentration moyenne de l'acide ascorbique du plasma était de 0,7 ± 0,2 mg/dl. De faibles corrélations non significatives (r = -0,01, -0,36) ont été observées entre les concentrations du glutathion érythrocytaire et de l'acide ascorbique du plasma. En conséquence, les valeurs du glutathion érythrocytaire étaient affectées de façon significative par celles de l'hématocrite et de l'hémoglobine, mais pas par celles de l'acide ascorbique du plasma.</jats:p
Concentrations du glutathion érythrocytaire des bovins zébus et Ndama nigérians
Une étude réalisée sur les concentrations de glutathion érythrocytaire des bovins zébus et Ndama nigérians a mis en évidence une variation allant de 40,8 à 135,1 mg/100 ml de globules rouges, avec une moyenne de 84,0 ± 25,4 mg/1o0 ml. On a observé une corrélation positive entre les concentrations de glutathion et l'hématocrite (r = 0,58, p0,05).</jats:p
