Effects of Season, Productive State, Age and Agro-ecology on Blood Biochemical Characteristics of Dromedary Camels (Camelus dromedarius) in Natural Browsing Environment

Background: Blood biochemistry and reference intervals assist in distinguishing between healthy and productive camels as well as providing information for nutritional conditions, evaluation and monitoring when they are allowed to browse naturally; nevertheless, these intervals are frequently collected from animals of varying ages. The nutritional condition and biochemical markers of dromedary camels in pastoral systems in southern Ethiopia were investigated in this study, which took season, animal status, age and environmental variables into consideration. Methods: A total of 36 camels were divided into three groups based on their age ( greater than 8 years, 5-8 years, or less than 5 years) and productive state (milking, pregnant and young) in two environments (two herds in arid and semi-arid areas). Blood samples were collected from animals’ neck jugular veins, centrifuged and frozen for analysis. The samples were centrifuged (3000 rpm for 10 min) immediately after their arrival at the laboratory. Serum concentrations of glucose, protein, urea, creatinine, triglycerides and cholesterol were measured using spectrophotometry. Result: This study shows that glucose (91.33+7.30 mg/dl), total protein (7.17+0.15 mg/dl) and triglyceride (75.28+5.38 mg/dl) concentrations were significantly higher (P less than 0.05) during the rainy season, whereas urea (32.06+1.18 mg/l) and creatinine levels were significantly higher during the dry season. The study reveals increased glucose, total protein and triglyceride concentrations in camels during the rainy season, while urea and creatinine levels were higher during the dry season. Arid camels had lower serum concentrations of total protein and urea. Milking and pregnant camels had lower total serum protein, triglyceride and cholesterol levels.
