Özet
A significant amount of herbaceous species provide to be an increasing of total organic matter depending on shrub intensity in the maquis vegetation. Therefore, the yearlong mineral contents of these herbaceous species and their importance in terms of goat feeding were investigated at this vegetation. The trial was performed in two different sites, including protected and grazed, for a period of 14 months in canakkale (October 2006 and November 2007), and therefore the plant samples were collected by mowing the dimensions of 0.5 m x 0.5 m ten frames in the middle of each month. The change of total 18 elements, including macro (N, P, K, Ca, Mg, S), micro (Fe, Mn, Cu, B, Na, Zn), and other elements (Se, Co, Ni, Cr, Cd, Pb), was investigated in the collected samples. According to the results of the study, the change of all elements except for Se was significant in both protected and grazed areas. In general, N, K, Mg, and S ratios of the plants increased from April, and they decreased in summer, autumn, and winter. P from the protected area at the beginning of the summer and from the grazed area in the spring increased. The change of Ca followed an opposite path. Iron rates were high in the winter and low in the summer; Mn and Cu were relatively high in the spring and very low in the summer; B and Na were excess in the spring and summer and few in the autumn and winter; Zn was high in the winter and low in the other months; Co, Ni, Cd, and Pb were high especially in the winter and lower in the summer; Cr was high in February and low in the other months. Se increased especially in spring. As the means of both areas, N, P, K, Ca, Mg, and S amounts of the plants were 12.45, 1.98, 10.78, 10.36, 2.07, and 1.45 g/kg, respectively, whereas Fe, Mn, Cu, B, Na, and Zn amounts were 676.2, 143.0, 6.3, 23.4, 1497.5 and 27.3 mg/kg, respectively. In evaluation based on the goats which were fed with 1 kg hay per day, N in early summer and autumn, K from the grazed area in the summer and autumn, Mn in the summer and 5, Cu, and Zn throughout the year were determined as insufficient, whereas there was not found any shortage for the other nutrients.
