520 3 _aConsidering climate change, camels, as drought-resistant animal species, have become a crucial component of the pastoralists' economy, ecology, and culture. They exhibit an extraordinary capacity to adapt to harsh environments. Most camels rely on grazing on natural rangelands to meet their daily nutritional requirements. Climate and watering intervals influence the foraging behavior of camels, as well as forage quality and availability. This experiment was conducted to investigate the effects of adding a concentrate feed mixture (CFM) on camel performance, forage consumption and digestibility, and energy usage in arid-area rangelands during the dry season. Eighteen dry and non- productive she-camels aged 8–10 years and weighing an average body weight (BW) of 438 ± 5.7 kg, were used to investigate the effects of CFM addition on camel performance and forage utilization in arid-area rangelands throughout the drought season. The camels were distributed into three treatments, each with six, and the CFM was individually given in separated feeders before grazing at 0% (control), 50% (low), and 100% (high) of the metabolizable energy requirements used for maintenance.. The herd grazed daily from 08:00 to 18:00 in an area dominated by Ababasis articulate, low-quality forage containing more than 70% neutral detergent fiber. Adding a high level alleviated animal deterioration by reducing weight loss from −1049 to −192 g/day and significantly increasing dry and organic matter digestibility. A substantial drop in forage consumption, accompanied by a significant adverse effect on fiber digestibility (P<0.01), was observed with addition. The Global Positioning System results revealed that the high addition considerably reduced (P<0.01) the distance traveled from 25 to 13 km, leading to lower (P<0.01) walking and grazing activity and higher (P<0.01) standing and resting time. The results were consistent with energy expenditure data, reflected in a more incredible retained energy for high vs. low or control levels of the concentrate.
