ABSTRACT
Nutrient composition and in vitro dry matter (DM) digestibility of leaves of five wild trees (Acacia modesta, Pistacia attlantica, Pistacia Khinjuk, Olea cuspidate and Zizyphus mauritiana) and five cultivated trees (Prunus dulcis, Pyrus malees, Prunus persica, Prunus domestica and Punica granatum), collected from three different locations in Balochistan. Were determined. Ash, crude protein (CP), neutral detergent fiber (NDF), acid detergent fibre (ADF) and in vitro dry matter digestibility (IVDMD) varied (P>0.001) due to tree species, but were not affected by location. Ash contents ranged from 4.62 to 17.02 percent of dry matter (DM) and remained higher in the cultivated tree leaves. CP in DM ranged from 7.17 percent in Olea cuspidata to 15.19 percent in Acacia modesta. Mean CP across all the species was 11.10 percent in DM. The ADF and NDF in the leaves ranged from 12.71 to 30.41 and 14.25 to 40.95 percent of DM, respectively. IN vitro DM digestibility varied from 13.80 percent in Pistacia attlantica to 70.78 percent in Prunus persica. Cultivated tree leaves were low (P<0.01) in ADF and NDF and 66 percent more digestible (P<0.001) than the wild trees leaves.
