This study was carried out in southern Darfur, Sudan during dry-and green (wet) season and was designed to investigate the effects of season (dry-versus green season) on the blood constituents of the one-humped camel (Camelus dromedarius). Two hundred and ten blood samples collected from apparently healthy one-humped camels (Camelus dromedarius) of different age and sex groups were used in this study, out of which 110 blood samples were collected during the dry season, while 100 blood samples were collected during the green season. The data analysis revealed that the season had significant effects on some of the haematological indices and the blood metabolites and minerals concentrations. The red blood cells count, lymphocytes and basophils percentages increased significantly during the dry season, while the osmotic resistance, MCV, MCH and neutrophils percentage increased significantly during the green season. The serum levels of total protein, globulins and triglycerides increased significantly during the dry season, while the concentrations of plasma glucose and serum urea, creatinine, phosphorus (P) and calcium (Ca) increased significantly during the green season. The results obtained in the present study indicate that the nutritional status could induce significant changes in the physiological responses of the dromedary camel. The available forage during the green season improved the body condition, the blood metabolic and mineral profile in camels. The results indicate that despite camel's selectivity and unique adaptation to arid conditions; glucose, urea, P and Ca levels were lower during the dry season. Therefore, it could be beneficial to provide concentrate feed to camels kept under dry tropical conditions.
本研究于苏丹达尔富尔南部的旱季和雨季（湿季）开展，旨在调查季节（旱季与雨季）对单峰骆驼（骆驼属单峰驼）血液成分的影响。本研究使用了从不同年龄和性别的看似健康的单峰骆驼（骆驼属单峰驼）采集的210份血样，其中110份血样在旱季采集，100份血样在雨季采集。数据分析显示，季节对一些血液学指标、血液代谢物和矿物质浓度有显著影响。旱季红细胞计数、淋巴细胞和嗜碱性粒细胞百分比显著增加，而雨季渗透压抵抗力、平均红细胞体积、平均红细胞血红蛋白含量和中性粒细胞百分比显著增加。旱季血清总蛋白、球蛋白和甘油三酯水平显著升高，而雨季血浆葡萄糖和血清尿素、肌酐、磷（P）和钙（Ca）浓度显著升高。本研究获得的结果表明，营养状况可引起单峰骆驼生理反应的显著变化。雨季可获得的草料改善了骆驼的身体状况、血液代谢和矿物质状况。结果表明，尽管骆驼具有选择性且对干旱条件有独特的适应性，但旱季葡萄糖、尿素、P和Ca水平较低。因此，给饲养在干燥热带条件下的骆驼提供浓缩饲料可能是有益的。
