Conteúdo: | Rice straw (RS), sugar-cane tops (CT) and sorghum tops (ST) were evaluated in separate trials using West African Dwarf sheep and goats. Each trial was a double 3 X 3 Latin Square design with the two species representing the squares; animals and time periods made up the rows and columns of each square. Values of each test roughage were predicted by regression from treatment means: treatment A (control)-Pangola hay; treatment B-two-thirds Pangola hay, one-third test roughage; treatment C-one-third Pangola hay, two-thirds test roughage. Sheep consumed more (P<O·OI) roughage dry matter (DM), and DM/kg·'5 and organic matter (OM)/kg'75 than goats in each trial although animals of similar age and body weight were used. Sheep DM intake averaged 1·7 times that of goats. Some of the intake differences may be attributed to differential adaptability of species to close confinement in metabolism crates. In only one trial (RS) did sheep digest feed DM and OM better than goats although TDN values were similar in each trial. Overall, the differences in species digestibilities were negligible. Test roughage DM intakes were predicted to be 71, 82 and 88 per cent of Pangola hay intake for RS, CT and ST respectively. DM digestibility was predicted to be 42,6, 41· 5 and 38· 5 per cent or 83, 85 and 77 per cent of hay for RS, CT and ST respectively. Combining intake and digestibility data, CT appears to be the most valuable of the three roughages being worth approximately 70 per cent of the value of Pangola hay harvested at 60 days regrowth. Low performance can be expected from RS, primarily because of low intake, and from ST because of low digestibility
