摘要：A study was conducted to determine the chemical composition , in vitro dry matter digestibility and in vtro fermentation of four dorminant browse species in the region of experimentation ( Leuceana lecocephala, Moringa Oleafera, Acacia tortilis and Ziziphus mucronata ). Crude Protein (CP) (from 13.96% DM for A. tortilis to 19.42% DM for L. leucocephala ) except M. oleifera which had the highest (21.42% DM). The range of lignocelluloses (acid detergent fibre, ADF) was from 21.16 g/100 g DM for A. tortilis to 31.39 g/100 g DM for M. oleifera . The netral detergent fibre ranged from 33.31 g/100 g DM for M. oleifera to 58.81 g/100 g DM. CF, EE and ash had a range of 20.00% DM for Z. mucronata to 32.53% DM for M. oleifera , 3.03% DM for A. tortilis to 5.33% DM for Z. mucronata and 10.76% DM for A. tortilis to 17.76% DM for L. leucocephala . The Total Condensed Tannin (TCT) for the browses ranged from 0.25 mg/g DM for M. oleifera to 2.96 mg/g DM for L. leucocephala . Z. mucronata had the highest value for Calcium (Ca), Magnesium (Mg), Sodium (Na) and Potassium (K) except for phosphorus. In vitro gas and methane production was highest in Z. mucronata . The IVDMD ranged from 70.66-72.00%. CP and TCT showed a positive relationship with IVDMD.
