摘要：The aim of present study was to find out the margin macro-mineral composition of 15 different fodder tree leaves and shrubs of district Chakwal of Pakistan. The climate of this region is characterized by a moderately low annual rainfall (350-500 mm.) Temperature during winter is 4-25°C and during summer is 15-40°C. Samples of fifteen tree leaves ( Acacia nilotica, Acacia modesta, Albizzia lebbeck, Capparis decidua, Elaeagnus angustifolia, Grawia optiva, Gymnosporia royleana, Indigofera gerardiana, Morus alba, Prosopis cineraria, Panicum antidotale, Nerium odorum, Moringa oleifera , Ziziphus mauritiana and Zizyphus mummularia) were collected in march and April and analyzed for macro-minerals, i.e. Na (Sodium), K (Potassium), P (Phosphorus) and Ca (Calcium). The mean percentage values for Ca, P, Na, and K were 1.66, 0.26, 0.08 and 0.069, respectively. Our current investigations on nutritional evaluation of fodder tree leaves and shrubs revealed that these are good source of macro-minerals and can be used as substitute feed in the district of Chakwal, especially during the feed deficient periods.
