Abstract
Foliage of some non-leguminous plants was examined by their chemical composition and in
vitro gas fermentation characteristics. Dry matter (DM), crude protein (CP), crude fibre (CF) and
ash level of the browse species ranged between 27.75 and 43.99, 5.43 and 20.93, 26.53 and
40.09, 5.37 and 11.52 % respectively. Neutral detergent fibre (NDF, 32.08-65.33 %), acid
detergent fibre (ADF, 22.08-49.61 %) and acid detergent lignin (ADL, 5.76-12.60 %). The gas
volume (GV) and methane produced at 24hrs incubation varied significantly (P<0.05) among the
species with values 13.50-25.50 and 8.00-13.50 respectively. Organic matter digestibility (OMD,
36.13-54.22%), Metabolizable energy (ME, 4.72-6.74 %) and Short chain fatty (SCFA, 0.26-0.55
%) also varied greatly among plant species. The result revealed that some of the plants studied
could be proved to be useful to ruminants as dietary supplement to poor quality dry season feed
since their protein concentrations are above the minimum recommended level.
