Seasonal Variations in Hemato-Biochemical Parameters in Mature One Humped She-Camels in the North-Western Coast of Egypt

Abstract

The study was conducted on four adult non-pregnant and non-lactating, onehumped she-camels, from March 2002 to February 2003 to cover the four seasons of the year. The study aimed to monitoring monthly and seasonally changes in hematological parameters and plasma biochemical constituents. Season of the year significantly affected (P<0.01) all hematological parameters studied. Erythrocyte counts, packed cell volume, hemoglobin concentration and mean cell hemoglobin concentration were higher during the coolest and lower during the hottest seasons; an inverse trend was observed for mean cell volume. Significant seasonal changes in total leukocyte counts were observed, with values being higher in winter (16.87 x 10 3 /mm 3) and lower in summer (14.61 x 10 3 /mm 3). Neutrophils were the major type of leukocytes in camels with highest percentage during summer (53.8%) and lowest during winter (44.1%). However, lymphocytes increased during the cooler seasons (48.1 %) and decreased in the hottest ones (40.1 %). Significant (P<0.05) seasonal differences were observed for almost all plasma biochemical parameters studied. Plasma total proteins were higher in summer (7.33 g/dl) than in winter (6.59 g/dl). Albumin tended to increase during summer and autumn and decreased during spring and winter as well as globulin but with insignificant differences. Overall mean values of urea and creatinine were 30.97 and 0.9 mg/dl, respectively with values being higher in summer and autumn, with similar trend for total lipids. Cholesterol values tended to increase from the lowest value in spring (56.6 mg/dl) to reach higher levels in both autumn (75.3 mg/dl) and winter (65.6 mg/dl) seasons. Glucose concentration and liver transaminases were also discussed. In conclusion, changes which might occur in hematological parameters during different seasons of the year might have an important role in adjusting the different functions of the animal's body with less physiological efforts within the so called neutral zone to the existing environmental conditions.

Mystery Behind Camel Mortalities in Khyber Pakhtunkhwa (Lakki Marwat), Pakistan

“…There is a negative correlation between hematocrit values and atmospheric temperature. This statement is in agreement with the findings of Badawy et al (2008) that in the summer season, there is a reduction of circulating erythrocytes and an increased rate of destruction of RBCs which results in decreased PCV. Anemia was classified as microcytic normochromic based on erythrocytic indices because the mean corpuscular volume was significantly decreased while MCH and MCHC were in the normal range.…”

Haematological and Biochemical Profile of Extensive Kept Male Barela (Camelus dromedarius) Camel during Breeding and Non-Breeding Season

“…T he dromedaries are of unique importance especially in the tropical environment as they can survive and produce in harsh and hostile extreme conditions equally to other domestic livestock species (Kadim, 2013;Faye, 2014;Faraz et al, 2019). In order to adjust body functions with environment and physiological condition, the variations in physiological factors are seem to put solid effect on blood parameters (Badawy et al, 2008). The blood parameters both hematological and biochemical are health condition signals and their studies could provide ample clue about animal health and physiological condition generally (Momenah, 2014) in fact, may serve as a mirror (Faraz et al, 2018).…”
