Haemogram and Serum Biochemical Values of Four Indigenous Species of Monkeys in South West Nigeria.

Haematological and serum biochemical values are useful guides and biomarkers in health and diseases for reaching a diagnosis, estimating disease prognosis and monitoring treatment progress, in mammals. Reference ranges for some parameters differ among species of mammals and between sexes within a species. There is dearth of information on standard reference value for blood parameters for Nigerian indigenous monkeys. Whole blood and serum samples obtained from 50 apparently healthy adult monkeys in both captivity and from the wild in southwest Nigeria were subjected to haematology and serum biochemistry to obtain preliminary reference values for haematological and serum biochemical analytes for Cercocebus sebaeus (Green monkey), Cercopithecus mona (Mona monkey), Erythrocebus patas (Patas monkey) and Papio anubis (Anubis baboon). Numerical data were summarized as mean and standard deviation and subjected to statistical analysis; Student t test and analysis of variance, to compare values of blood parameters obtained between species and gender. A p-value less than 0.05 was considered significant. The hematocrit of male animals were significantly higher than that of females (P=0.01) in all the 4 species studied but there was no significant difference in other blood parameters such as total white blood cell and the differential counts, platelet count, serum aspartate transferase, alanine transferase, alkaline phosphatase, total plasma protein, albumin, and globulin concentrations between the sexes. Generally, there was no significant difference between total white blood cell and the differential counts, hematocrit, red cell count, haemoglobin concentration, platelet count, serum aspartate transferase, alanine transferase, alkaline phosphatase, total plasma protein, albumin, and globulin concentrations among the monkey species.

Electrocardiographic and Blood Pressure Measurements in Captive African Lions (Panthera leo) Immobilized with Xylazine-Ketamine Combination.

Electrocardiographic and blood pressure measurements are extremely valuable diagnostic tools in the evaluationof the cardiovascular system of living animals. In this study, 6-lead electrocardiograms were recorded from five male captiveAfrican lions (Panthera leo). Also, blood pressure measurements were recorded and compared from three different sites;fore limb, hind limb and the tail, were recorded. Immobilization was done with a combination of Ketamine Hydrochloride(10mg/kg) and Xylazine (3mg/kg). Measurements were recorded as mean ± standard deviation. ECG readings were analysedusing descriptive statistics while blood pressure readings were compared using ANOVA at a 5% level of significance. Heartrate was 66±11.6 beats per minute. The heart rhythm was sinus in all the animals. Mean Electrical Axis (MEA) was between+810 and +930 degrees (Mean +89±5). Three animals had their MEA between +810 and +890 while two had MEA between+910 and +930. Fore limb measurements for Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DAP) and MeanArterial Pressure (MAP) were 177.6±6.8 mmHg, 157.2±5.9 mmHg and 168.6±5.2 mmHg respectively. Hind limbmeasurements for the SBP, DBP and MAP were 135.4±9.5 mmHg, 120.6±5.9 mmHg and 123.0±6.8 mmHg respectivelywhile the tail measurements for the SBP, DBP and MAP were 149.6±8.3 mmHg, 132.8±5.9 mmHg and 137.2±5.8 mmHgrespectively. There was weak correlation between forelimb vs hindlimb and forelimb vs tail comparisons of SBP, DBP andMAP. However, a strong positive correlation was found between hindlimb and tail comparisons of those parameters. Resultsfrom this study should serve as a guide in the cardiovascular monitoring of captive African Lions immobilized with axylazine-ketamine combination.

A Comparison of Surface Infrared with Rectal Thermometry in Dogs.

Accurate determination of temperature is crucial in the diagnosis of febrile conditions. Although fewer techniques have proven as useful and reliable a predictor of core body temperature as the rectal thermometry, the process of obtaining the rectal temperature could be stressful in dogs. The infrared thermometry is a noncontact device used for measuring body temperature, with advantages which include speed, convenience, and reduced stress to the animals and reduced occupational risks to the animal handler. Therefore, there is the need to assess the consistency and agreement between non-contact infrared thermometry and traditional rectal thermometry in body temperature estimation. This study compared and assessed the sensitivity of non-contact infrared thermometer used on the forehead and nasal regions respectively with that of a rectal thermometer in dogs for body temperature estimation. One hundred and thirty (130) dogs presented for veterinary attention at the Veterinary Teaching Hospital (VTH), University of Ibadan, Nigeria were enrolled in this study during August to September 2014, irrespective of sex, age, breed or health status. Temperatures of dogs presented at the clinic were obtained using both multiple non-contact infrared thermometric measures obtained in the nasal and frontal head regions; and by rectal temperature. A multivariate cross-matrix analysis was used to assess the difference in measurements between the rectal thermometry and non-contact infrared thermometry. Descriptive statistics was used to compare variation and trend regularity of the nasal and fore-head infrared thermometry. A logistic regression of the difference in measurements was computed at 95% confidence interval and P<0.05. The mean difference revealed that the rectal temperature was 5.330C higher than the non-contact infrared forehead-based temperature and 7.570C higher than nasal-based temperature measurements respectively. The Bland-Altman (B-A) plot showed that the 95% limits of agreement between the frontal and nasal obtained infrared laser thermometry methods. Temperature measure obtained using non-contact infrared thermometry (forehead and nasal region of the head) was poor in consistency and agreement compared to rectal thermometry. Usefulness of non-contact forehead infrared thermometry in routine clinical practice as a close estimate of core body temperature depends on accurate calibration and therefore not recommended.
