Studying Some Chemical Compositions of Sphaerocoma aucheri in Sandy Ranges of Persian Gulf

Having knowledge about the quality of range plants for doing the effective management of ranges in order to evaluate the grazing capacity is essential and determining the forage quality is one of the important factors which is necessary for the correct management of ranges. In this paper, the forage quality of Sphaerocoma aucheri as one of the most important species of coastal ranges of Hormozgan was studies in 3 stages: growth, flowering and seeding and the other parts such as leaves, tip of branches and type of flower were studied. for analyzing this plants, at first, plants samples were collected in 3 stages and then the samples were transferred to the laboratory and these parameters were measured by the usual methods/AOAC as dry material/ DM, protein percentage/CP, unsolvable fibers in acidic detergent/ADF, ash, phosphorus/P, potassium/K, sodium/Na, and magnesium/Mg. The results show that there is a significant difference between most of considered meta-measures in various phonological stages and in different parts of a plant. The amount of CP, ash, P, and Na in leaves is more than flowers and also amount of DM, ADF and P in tip of branches is more than leaves.
