Abstract: This study has been conducted in order to study the possible correlations between the nutritional value of plants selected by camels during the dry and green season and the corresponding blood and milk composition of the dromedary camels. The study has been conducted on 50 indigenous Arabian camels of different age and kept under natural range in Southern Darfur. The dromedary camels selected plants with significantly (p<0.05) higher crude protein content during the dry season and kept the serum albumin concentration and milk protein content at the same levels as those observed during the green season. However, the significantly (p<0.05) higher lipogenic content (ether extract + crude fiber) of the plant selected during the dry season resulted in significantly (p<0.05) higher serum triacylglycerides concentration and significantly (p<0.05) higher milk fat content compared to that of the green season. Although, the camels selected plants with significantly (p<0.05) higher nitrogen free extract content during the dry season, the plasma glucose level and the milk lactose content were significantly (p<0.05) reduced compared to that of the green season. The significantly (p<0.05) lower ach content of the plants selected during the dry season resulted in significantly lower serum calcium + phosphorus concentration, but did not reflect on the ash content of the milk. The results indicate that despite camels selectivity and unique adaptation to arid conditions, the milk lactose-and fat content were affected by the nutritional scarcity during the dry season. Therefore, it could be beneficial to provide energy-rich feed supplemented with calcium and phosphorus to camels kept under dry tropical conditions.
