Abstract：
Selecting highly nutritive fodder plants in arid regions can be a key to improving the livestock productivity. This work explores the variation in nutritive value of the leaves, stem, and shoots of five potential fodder plants of the Emirates of Fujairah, Erucaria hispanica, Haplophyllum tuberculatum, Convolvulus virgatus, Teucrium stocksianum, and Cleome Ibrachycarpa. influenced by two weather conditions, winter and spring. The plant samples underwent mineral composition, proximate, phytochemical, and heavy metals and two-way ANOVA. Weather data were accessed from National Center of Meteorology (NCM). Our findings reveal significant influences of collection time and species on nutritive content. Shoots collected in March exhibited higher ash (6.167%), crude protein (11.9%), crude fiber (14.89%), dry matter (45.86%), and total digestive nutrients (TDS) (48.35%), with lower tannin (5.11%) compared to January. Conversely, January-collected shoots had greater total sugar content (1.28 g/100 g). Plant organs played a crucial role, with leaves surpassing stems in Mg, P, Ca, K, Na, Mn, Zn, and Ni. Leaves also showed higher crude protein (23.33%), dry matter (92.26%), total ash (4.8%), and TDS (87.58%) compared to stems, while stems exhibited elevated crude fiber (17.45%) and tannin (4.53%). There is a need to assess the bioactive compounds found in these fodder species for the enhancement its effective use and maximize browsing of these species.
摘要：
在干旱地区选择高营养的饲料植物可能是提高畜牧业生产力的关键。这项工作探索了叶子的营养价值变化，茎,以及富查伊拉酋长的五种潜在饲料植物的芽，西班牙Erucaria,单叶结核，处女盘旋,龙骨，还有CleomeIbrachycarpa.受两种天气条件的影响，冬天和春天。植物样品经历了矿物成分，接近，植物化学，重金属和双向方差分析。从国家气象中心（NCM）访问了天气数据。我们的发现揭示了收集时间和物种对营养成分的显着影响。3月份收集的枝条显示出较高的灰分（6.167%），粗蛋白(11.9%)，粗纤维(14.89%)，干物质(45.86%),和总消化营养素(TDS)(48.35%)，与1月相比，单宁降低（5.11%）。相反，1月收集的芽的总糖含量更高（1.28g/100g）。植物器官起到了至关重要的作用,叶子超过Mg的茎，P,Ca,K,Na,Mn,Zn,和Ni。叶片也显示出较高的粗蛋白（23.33%），干物质（92.26%），总灰分（4.8%），与茎相比，TDS(87.58%)，茎表现出粗纤维(17.45%)和单宁(4.53%)升高。需要评估在这些饲料物种中发现的生物活性化合物，以增强其有效利用并最大程度地浏览这些物种。
