Some top foliages namely mango (Mangifera indica), kikkar (Acacia nilotica), amla (Emblica officinalis), ber (Zizyphus nummularia), neem (Azadirachta indica), peepal (Ficus religiosa), jamun (Syzygium cuminii), subabul (Leucaena leucocephala), mulberry (Morus alba), kachner (Bauhinia variegata), sirin (Albizia lebbeck), dhaman (Grewia optiva) were evaluated for chemical composition, tannins fractionation and protein binding affinity of tannins. Crude protein content (%) ranged from 10.62 ± 0.57 in mango to 28.01 ± 0.43 in sirin (Albizia lebbeck) and others were within this range. Nitrogen free extract content (%) ranged from 42.55 ± 0.43 to 67.72±1.53. The NDF content (%) ranged from 17.22 ± 0.05 to 47.12 ± 0.12. Total tannin (tannic acid equivalent) content was in the order of kikkar> amla> mango> ber> subabul > kachner> sirin>jamun>peepal>mulberry>bedoh>dhaman>neem while, condensed tannin (leucocyanidin equivalent) content was in the order of mango>subabul> kachner> ber> amla> kikkar> neem> jamun> mulberry> bedoh> dhaman> peepal> sirin. The protein precipitable phenolics (mg/100g tannins) ranged from 9.96 ± 0.00 in subabul to 94.11 ± 0.89 in jamun while protein precipitable phenolics (mg/100g sample) ranged from 0.50 ± 0.00 in subabul to 12.49 ± 0.09 in amla. Protein precipitable phenolics could not be detected in neem, peepal, mulberry, sirin, dhaman and bedoh. It is concluded that neem, peepal, mulberry, sirin, dhaman and bedoh can be used as high quality fodders and mango, subabul, kachner, ber, amla and kikkar can be used as medium quality fodders in hilly areas for ruminants where there is scarcity of fodders.
