Thirty two Bach Thao goats with an initial weight of 15.3 kg at 4 months of age were used to study the nutritive value of chopped cassava stems supplemented with Guinea grass or one of three protein-rich foliages - fresh cassava foliage (CF),  cassava hay (CH) or fresh jackfruit foliage (JF). Highest values for total DM intake were recorded with supplements of fresh cassava foliage and jackfruit with the lowest value when the supplement was Guinea grass.  Growth rates were increased by 79%, and feed conversion improved by 34%, when the cassava foliage was fed fresh rather than being made into hay;  while compared with Guinea grass the growth on fresh cassava foliage as the supplement was 99% greater and the DM feed conversion 35% better.
