Abstract
This research work is designed to investigate the proximate and elemental composition of six selected plant species at three different phenological stages i.e. pre-reproductive, reproductive and post-reproductive. The plants Prunus dulcis, Rumex hastatus, Capparis spinosa, Sorbaria sorbifolia, Santolina chamaecyparissus and Calamagrostis pseudophragmites showed uneven increases and decreases in several micro-macronutrients across phenological phases. The number and concentration of nutrients have a great potential to keep cattle healthy and on a balanced diet. The proximate analysis showed that Capparis spinosa had the highest content of dry matter (94.62%) among the six species. Sorbaria sorbifolia was investigated with the highest concentration of Ash (17.35%) and Crude protein (18.16%). Maximum Crude fat was noticed in Rumex hastatus (14.92%). While, the highest crude fiber (32.62%), ADF (56.49%) and NDF (74.965) were observed in Calamagrostris pseudophragmites. In the case of elemental analysis, the highest concentration of the macro-nutrient Calcium with 79.74 mg/kg and Fe with 0.984 were noticed in Calamagrostris pseudophragmites, while Mg containing 7.987 mg/kg and Zn 0.314 mg/kg were detected in Prunus dulsis. In addition, Sorbaria sorbifolia showed the highest concentration of Potassium having 16.22 mg/kg and Cd 0.117 mg/kg. Last but not least Capparis spinosa showed a maximum concentration of Manganese of 2.77 mg/kg. The nutritional composition of the selected plants found within permissible limits and the concentration were in line with those reported in other regions of the world and Pakistan.
