                            Abstract

                            This experiment was conducted to determine macro mineral solubility of forages harvested in south sumatera, indonesia during dry an rainy seasons. The species of forages evaluated was the same as reported in the previous study. The mineral solubility was determined byin situ nylon bag technique through incubation of the forages sample in the rumen at 0,24 and 72hr. Results of experiment showed that solubility of Ca, P, Mg and S significantly affected by species and seasons (p,0.05). Mineral solubility increased as increasing period of incubation from 0 to 72 hr. At 0 hr incubation (water solubility), P and Mn were the most soluble minerals, while in legumes the highest water solubility was found for Mg. Coversely, Ca was solubilized lower than the other observed mineral. Among species of forages, P. Purpuphoides (grass) and L. Leucocephala (legume) contained highly water soluble mineral compared to the other species. Data on 72 hr incubation period (actual solubility) showed that P was the most soluble minerals in grass followed by Ca, S and Mg. However, the highest mineral solubility in legumes was occured in Ca, followed by Mg, S and P.consistent with mineral concentration, among the forages evaluated P. Purpuphoides (grass) and L.leucocephala (legume) had higher mineral solubility compared to the other species. key word : Rumen Solubility, macro mineral, rainy and dry seasons.
