Dry matter yield (DMY) per cutting was higher (P0.05) with the wet season and with longer cutting interval. Per annum basis, DMY did not differ significantly between the two cutting frequencies but was found higher (P0.05) with one site compared to the other four. Stocking rate was estimated at 10 small ruminant equivalents (range of 5-15). More frequent cut herbage had higher protein and lower calcium contents (P0.05). Dry season forages were more digestible (P0.05) and higher (P0.05) in dry matter, crude potein and calcium but lower (P0.05) in ash and cell wall analyses. No significant effects of season and cutting interval were found on botanical composition of the vegetations. Across the seasons and cutting intervals, grasses predominated the pastures followed by broadleaves, legumes and lastly shrubs/trees. Differences between the two means of the types of vegetation were significant (P0.05). The most predominant grasses were Axonopus compressus, Paspalum conjugatum and Cyrtococcum sp.; legumes, Mimosa pudica, Pueraria phaseoloides and Pueraria Lobata; and broadleaves, Ageratum conyzoides,
