Proximate composition and mineral profile of elephants forages in the Savannah ecological zone of Ghana

Abstract

ABSTRACTThis study evaluated the proximate and mineral composition of various parts of Balanites aegyptiaca, Mitragyna inermis, Cassia sieberiena, Kigelia africana, Detarium microcarpum, Terminalia laxiflora, Ficus platyphylla and Climber plant (Liana) as feeds of elephants in the savannah ecological zone of Ghana. The proximate composition was carried out using the methods of the Association of official analytical chemists (AOAC) and the mineral profiles were determined by atomic absorption and flame photometric methods. The highest content of Crude Protein, Crude Fibre, Ash, Moisture and Nitrogen free extract were 12.0% ± 0.01, 15.3% ± 0.01, 14.6% ± 0.0, 7.5% ± 0.01, 76.6% ± 0.01 for Ficus platyphylla, Tamarindus indica, Balanites aegyptiaca and Detarium microcarpum, respectively. The mineral profiling also found appreciable levels of Ca, Mg, P, K, Na, Zn, Cu, Fe, Se and Mn at concentrations (mg/kg) of 4.6 ± 0.00, 0.4 ± 0.01, 0.4 ± 0.01, 5.1 ± 0.01, 0.11 ± 0.01, 1.07 ± 0.008, 0.25 ± 0.005, 0.063 ± 0.0005, 37.48 ± 0.001 for Ficus platyphylla bark, Liana, Terminalia laxiflora bark and leaves, Mitragyna inermis bark, Terminalia laxiflora leaves and Mitragyna inermis leaves, respectively. Presentation of the presence of these important nutrients would be a guide to zoo managers and wildlife practitioners on the best quality of feeds to select for wild elephants.
