Five goats (Bach thao breed) of 11.76.4 kg live weight receiving a basal diet of ad libitum ammoniated rice straw (4% urea treatment) were allocated to a 5*5 Latin Square arrangement to compare forage supplements (10 kg/100 kg live weight, fresh basis) of: G, fresh grass; GC1, fresh grass and fresh cassava leaves (75:25 DM basis); GC2, grass and cassava leaves (50:50 DM basis); GC3, grass and cassava leaves (25:75 DM basis); and C, fresh cassava leaves. Increasing the intake of cassava leaves over the range 0 to 47% of the diet DM led to related increases in all measured parameters: intake of ammoniated rice straw, total organic matter and total dry matter; digestibility of organic matter, N, crude fibre and ash; and daily retention of N.
