Description
The chemical composition and in vitro dry matter (DM) and cell wall digestibility of different legumes, i.e, berseem (Trifolium alexandrinum), cowpea (Vigna sineuis),, guara (Cyamopsis tetragonolob), lucerne (Medicago sativa), metha (Trigonalla foeawmgroecun) and white senji (Melillotus alba); and non-legumes, i.e., bajra (Pennlsetum typloides), sorghum (Sorghum vulgare), maize (Zea mays), oat (Avena Sativa), PP grass (Pennisetum pedicellatum), sudan grass (Sorghum sudanese) and teosinte (Euchlaena maxicane) forages were determined. The correlation coefficients between ill vitro digestibility and various chemical components (NDP, ADPlignin, cellulose, hemicellulose and crude protein) of these two groups of forages had significant correlation (P<0,01) with the in vitro digestibility (IVDMD). NDP content was found to be the best predictor of percentage IVDMD. A digestion trial with 18 non-pregnant dry adult cows was conducted to investigate the relationship between IVDMD and in vivo DMD, The average DMD coefficients for berseem, lucerne and oat were 66.3, 67.1 and 64.2% respectively. A close correlation (r=0.91) existed between in vitro and in vivo digestibility coefficient, A significant correlation (r=0.8, P<0,01) existed between DM intake and % DMD. A significant correlation (r=0.8, P<0,01) was found between nutritive value index (NVI) and in vitro DMD coefficients. Proposed equations for predicting digestibility/nutritive value of Indian forages are calculated.
