Tree leaves and other uncultivated fodder plants are the major source of roughage available for dairy animals in the hills. Representative samples of 14 fodder plants were collected from hill and tarai region of Uttaranchal and evaluated for their chemical composition and nylon bag digestibility. The DM, OM, CP, NDF and ADF contents in different fodder species ranged from 22.67 (F. arundinacea) to 45.16 (Dimeria spp.),86.00 (D.glomerata) to 91.80 (T.triandra), 8.30 (T.triandra) to 21.19 (D.velutina), 54.70(R.pseudoacacia) to 68.50(T.triandra) and 36.93 (R.parviflora) to 49.61% (A.nepalensis) respectively. Tannin content in these plants varied from 1.45 (B.rugulosa) to5.92% (A.lebbeck). Digestibility of fodder was studied using nylon bag technique (in sacco) on 3 remen fistulated male animals. In sacco digestibility of DM,CP,NDF and ADF ranged from 43.07 (R.pseudoacacia) to 74.83(F.arundinacea),52.63(T.triandra) to 75.75 (F.arundinacea), 50.46 (A.nepalensis) to 83.13(F.arundinacea) and 31.23 (T.triandra ) to 69.28 (F.arundinacea), respectively, with significant (P0.05) differences. The fodder plants were scored by the selection index method considering their CP, NDF, tannin, and lignin contents and also in sacco DM digestibility. On the basis of the above, fodder plant leaves of B.regulosa, B. paprifera, F. arundinaced and D. velutina were found of high nutritive value and are suggested to be included more in the diet of animals of hill and the tarai region.
