Experiments were carried out at the farm of Angiang University from January to August 2011 to measure: (i) the effect of fertilization with biodigester effluent on biomass production of Tithonia diversifolia (Wild Sunflower); and (ii) the effect on intake and digestibility by growing goats of supplementing Tithonia diversifolia foliage with foliage from Sesbania sesban and/or Mimosa pigra. Biomass productivity of Tithonia was raised by 175% by increasing the level of fertilization with biodigester effluent from 20 to 60 kg N/ha. Feed DM intake was increased by from 11 to 23% and N retention by 30-32% when goats fed a basal diet of Tithonia were supplemented with foliage from either Mimosa pigra or Sesbania sesban, or the combination of both legume foliages.
