Nitrogen Solubility, Protein Fractions, Tannins And In Sacco Dry Matter Digestibility of Tree Fodders of Shiwalik Range
Eleven tree fodders commonly available in Sliivaiik range viz. Bauhinia variegata, Butea monosperma, Cassia spinarum, Ficus religiosa, Grewia optiva, Meliaazedarach, Morusalba, Oleaferruginea, Quercus dilatata, Q. leucotricophora and Salix alba were analysed for proximate and fiber composition, nitrogen solubility, fiber bound nitrogen, total phenolics, hydroiysable tannins, condensed tannins and in sacco DJV1D. There was wide variation In proximate and fiber composition. Nitrogen solubility was highest in 0.02N NaOH followed by that in borate phosphate buffer. The values ranged from 17.29% in O. ferruginea to 35.49% in M, alba. Almost 70% or more of total-N in the fodders studied was NDF bound and the values for ADF bound nitrogen ranged from 25.45% in S. alba to 73.50% in M, alba indicating wide variation in degradable fiber bound nitrogen. C. spinarum contained highest amount of CT followed by that in B, variegata. Negative and significant correlations were observed between DMD and NDF (P<0.05), DMD and ADF (P<0.05) and between hemicellulose and fraction C (P<0.01) while the correlations were positive and significant between N content and NDIN (P<0.01) and N content and ADIN (P<0.01). On the basis of the present studies, it appears that G, optiva, M. alba, F. religiosa, O, ferruginea and M. azedarach are good fodders for ruminants.
