Protein bound to acid detergent fiber (ADF-P) and in sacco digestibility of protein (ISPD) were determined in five wild (Acacia modesta, Pistacia attlantica, Pistacia khinjk, Olea cuspidata and Zizyphus mauritiana) and five cultivated (Prunus dulcis, Pyrus malees, Prunes persica, P. domestica and Punica granatum) tree leaves collected from three different locations in Balochistan. Tree species significantly influenced ADF- P (P less than 0.001) and ISPD (P less than 0.001) of the leaves. ADF-P was higher (P less than 0.01) in wild than cultivated tree leaves (19.23% vs. 9.01%). Conversely, ISPD was higher (P less than 0.001) in cultivated than wild tree leaves (54% vs. 18%). A negative relationship between ADF-P in tree leaves may be done of the major factor limiting bio-availability of protein. It is concluded that in tree leaves crude protein is not a good indicator of their protein value and in addition the leaves should be analyzed for ADF-P and or in sacco digestibility.
