Physiological and hematological parameters of sheep reared in the tropics and subtropics

ABSTRACT This study aimed to determine the physiological and hematological parameters of sheep in Brazil. Therefore, 5,081 observations were used from previous experiments with animals from different Brazilian regions with the time of day, gender, breed, age, physiological characteristics, hematological and climatic variables. The animals were classified according to their stress level, and only data of non-stressed animals were used to calculate the reference values. Respiratory rate was the parameter that most differed from the normal range, with values above the limits usually reported for the species, being higher in commercial wool sheep. For hematological variables, differences were observed between the present results and the previously reported values in the literature. A higher number of red blood cells (RBC), lower hemoglobin and mean corpuscular hemoglobin concentration (MCHC) were observed in young animals. A higher number of RBC and MCHC were noted in sheep crossed with local breeds. Considering that physiological and hematological parameters are indicators of the animal's pathological or physiological state, for a correct interpretation of the results, the use of reference values based on animals with similar racial characteristics and subjected to similar environmental conditions is recommended.

Hematological Indicators

The influence of the physiological state of rabbits (pregnancy and lactation) on the hematological parameters of blood during changes in the area of the plantar surface of the feet of the hind limbs in conditions of cage keeping was studied. In the body of pregnant females, with the appearance of signs of hyperkeratosis and alopecia in the studied area of the feet, an increase in hemoglobin level occurs, an increase in MCH (mean corpuscular hemoglobin), MCV (Mean Corpuscular Volume), MCHC (corpuscular hemoglobin concentration) occurs, followed by a decrease in the development of hemorrhagic changes. The level of red blood cells has slight fluctuations. In lactating females, with the occurrence of alopecia and hyperkeratosis, an increase in the level of erythrocytes and hematocrit occurs with a simultaneous decrease in hemoglobin, and against the background of the development of hemorrhages, these indicators decrease, a decline in the values of MCH, MCHS and an increase in MCV are recorded. Regardless of the physiological state of the animal and changes in the area of the feet, the erythrocyte sedimentation rate (ESR) value and the level of leukocytes fluctuate within the limits of physiological values, which indicates the absence of an inflammatory process in the body. he revealed hematological changes indicate the development of adaptive processes in the event of hyperkeratosis and alopecia in the area of the plantar surface of the feet at various physiological conditions of rabbits with subsequent decompensating against the background of hemorrhagic changes.

AbstractHematological parameters in healthy goats show several variations in relation to breed, age, reproductive status, environmental factors and management conditions. Therefore, there is the need to investigate these factors and how they affect the animal’s hematology. The aims of this study were to establish hematological reference values of five Italian goat breeds at different age classes (1–2, 3–4 and over 5 years) considered in autumn and to evaluate the effects of some factors (breed, age and environmental conditions). Ninety-six dried female Aspromontana goats, 102 Girgentana goats, 99 Messinese goats, 96 Maltese goats and 108 Argentata dell’Etna goats, clinically healthy, were used. Blood samples were collected from each animal and analyzed for Red Blood Cell (RBC), White Blood Cell (WBC), Hemoglobin concentration (Hb), Hematocrit (Hct), Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC) and Platelets (PLT). Statistical analysis showed the effect of breed (P<0.05) on all studied parameters and the effect of age (P<0.05) on: RBC and Hb in Messinese goats; Hct in Girgentana, Maltese and Argentata dell’Etna goats; MCV and MCHC in Argentata dell’Etna goats; WBC in Aspromontana goats; and PLT in Girgentana and Messinese goats. The findings of the present study may serve as reference values for hematology of Italian goat breeds studied in autumn which could help veterinarians to interpret laboratory data appropriately and to monitor animal health status in order to improve the management and conservation of these breeds.

Background: In Côte d’Ivoire, as in most developing countries, the reference values of hematological indices currently in use come from data collected from populations living in industrialized countries. The aim of this study was to determine variations in the child's blood count in Cote d'Ivoire. Materials and Methods: This descriptive cross-sectional study has focused on 310 children (172 girls and 138 boys) aged 5 to 11 years selected from three municipalities of Abidjan. Blood samples were taken from each child in order to assess the parameters of the blood count. Results: The results revealed that the means of the different hematological parameters (red blood cells, hemoglobin, hematocrit, white blood cells, neutrophils, eosinophils, monocyte, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration) were in accordance with the normal physiological reference values from the literature apart lymphocyte. The rate of lymphocytes (51.3 ± 0.5) was higher overall. All the parameters did not indicate significant differences between girls and boys (p > 0.05) except mean corpuscular volume, and mean corpuscular hemoglobin that were statistically different by sex (p < 0.05). The percentage of having a rate of haemoglobin lower than 11.5 decreased significantly (p˂0.005) when the age increased. In addition, the rate of hemoglobin and hematocrit increased slightly starting from the age of 8 years. There is a significant difference (p < 0.05) in hemoglobin level between girls and boys in the age group of 9 years. Leukopenia is observed in a minority of children in the age groups of 5, 6, 7, 8, and 10 years. Conclusion: Some hematological parameters were different from other data published in the literature, which suggested a local development of reference values for children.

ABSTRACT Objective: The objective was to determine the basic hematological parameters of remunerated blood donors in Benin City and to compare them with those of voluntary donors. Materials and Methods: This is a prospective study conducted in a tertiary health facility in Benin City. Pretransfusion samples were obtained from blood bags after gentle mixing and analyzed for hematological parameters. Samples were analyzed using the hematology autoanalyzer MODEL SYSMEX KN21. Result: A total of 215 samples were obtained comprising 160 remunerated (paid) and 55 voluntary donor samples. In the paid donors, the mean hemoglobin concentration (Hb) and hematocrit (HCT) 7.7±2.9 and 28.8±8.5 respectively. This was significantly lower than those of voluntary donors who had 13.9±1.2 and 42.2±3.3 with P < 0.001. The mean values of the red cell counts (RBC), white cell counts (WBC), mean cell volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were significantly lower in paid donors as P-values were <0.001. MCV was significantly low but not compared to the other parameters as P=0.04. There was no significant difference in the platelet count. Conclusion: Paid donors in Benin City have significantly lower hematological parameters than controls.

Anemia is a common feature of chronic kidney disease (CKD). The current management of patients with anemia in CKD is controversial. These make anemia is one of the leading causes poor outcome in CKD patients. Our study focus to assess the effect of statin on hemoglobin level with an experimental model of CKD. We perform the animal model of CKD by subtotal nephrectomy procedure. A total of 20 male swiss was used in these study. All the animal divided into 4 groups: sham group (S), nephrectomy (Nx), simvastatin group 5 mg/kgBB (SV5), and simvastatin group 10 mg/kgBB (SV10). Hematological parameters (hemoglobin (Hb), white blood cells (WBC), red blood cell (RBC), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC)), and serum creatinine are measured at the end of the study. The hemoglobin levels in the Ux group decreased significantly compared with the S group (11.02 ± 0.46 vs 14.3 ± 0.15, p<0.0001). While in the SV group, statin administration led to an increase in hemoglobin levels compared with the Ux group but not statistically significant (SV5: 13.26±0.34; Sv10: 12.68±0.26). These results suggest that administration of statins in CKD may improve the condition of anemia by an unknown mechanism, while still requiring other treatment options to maximize the effect of therapy.

Introduction: numerous biological parameters are physiologically modified during normal pregnancy, in particular hematology. The knowledge of these modifications of the maternal body by biologists and clinicians allows the screening of possible anomalies. In Morocco, the reference values of the complete blood count test for pregnant woman are missing, as are those specific to different trimesters of pregnancy. The aim of this study is to look for the reference values for healthy pregnant women of the Northwest region of Morocco, to compare them to those of non-pregnant women (control) and to those of the literature. Methods: blood samples were taken voluntarily from 3898 healthy pregnant women from 18 to 46 years old who presented themselves at the center of health Kalaa and at the service of gynecology obstetrics of the Provincial Hospital Center of M'diq (Morocco), for prenatal care. To establish the reference intervals of the CBC for non-pregnant women, a control group was constituted by 7035 healthy women from 18 to 50 years old selected according to the Moroccan law of blood donation. The CBC was measured on a Sysmex KX21N® analyzer. For each sample a systematic blood smear was done to determine the leukocyte differential. Results: a statistically significant difference between the pregnant women and control group was noted (p < 0.05) for all the hematological parameters: red blood cells, hematocrit, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, leukocytes, neutrophils, basophils, eosinophils, lymphocytes, monocytes, platelets and mean platelet volume. So, the comparison of the averages established between the first, second and third trimester of pregnancy showed the existence of a significant variation with regard to all the parameters of the CBC test looked for (p < 0.001). Conclusion: the present study provides additional baseline data for basic hematological parameters in healthy pregnant Moroccan women and concluded that pregnancy in women has the tendency to alter some hematological indices. For these reasons, there is an interest to take these modifications into account for optimal maternal and fetal medical care.

Hematology and blood chemistry reference values in wildlife animals are considered a key element to evaluate their health and welfare status. The incidence of birds rescued is increasing, thus, rehabilitation centers worldwide need valid reference values to improve medical care for wild individuals. The objective of this study was to obtain the reference values of the adult black-faced ibis (Theristicus melanopis). Blood was taken from adult rehabilitated birds and analyzed to obtain red and white line values such as hematocrit, hemoglobin, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), heterophils, lymphocytes, monocytes, eosinophils and basophils. Values for blood glucose, proteins, albumin, globulin, calcium, phosphorus, blood urea nitrogen (BUN), creatinine, alkaline phosphatase, aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH), creatine phosphokinase (CPK) and albumin:globulin (A/G) ratio were also obtained. The results were similar to others reported for species of the Threskiornithidae family (bald, glossy and Puna ibises), but showed higher values for white blood cells (WBC), heterophils, monocytes and heterophil-lymphocyte (H/L) ratio, but lower values for basophils and eosinophils. Moreover, higher values in albumin, BUN and CPK were observed. This is the first report of the hematology references values for the black-faced ibis showing differences to other closely related species. The results may be of use in rescue and rehabilitation centers for animal welfare and health assessments of the black-faced ibis.

Set Up

Mercury toxicity in tilapia, Oreochromis niloticus, (Linnaeus, 1758) was investigated by the hematological parameters after long-term (14 days) exposure to various Hg concentrations (0.02, 0.002, 0.0002mg/L Hg). Test groups were set up with three replicates for each concentration, plus the control group. Blood samples were collected from six individuals for each concentration at 0, 3, 7, 10 and 14 days of exposure. The hematological parameters analyzed were: total red blood cell count (RBC), hemoglobin concentration (Hb), hematocrit (Ht), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), total white blood cell count (WBC) and differential leukocyte counts and total thrombocyte count (Tr). There were no significant differences among the mean hematological values at the different Hg concentrations indicating that Hg at the concentrations studied was not toxic to tilapia.
