4. Discussion
The nitrogen content in the cassava peel (1.0%) was similar to results of Baah et al. (1999) and Osei and Twumasi
(1989) who reported values of 1.0% and 0.96%, respectively.Although the nitrogen content in the peel is marginal and
may be adequate for maintaining sheep on a diet composed of only cassava peel, it would not be able to support
any appreciable level of productivity. The crude protein (N×6.25) content of the chaya leaves (21.3%) found in this
study seemed lower than the 27% reported by Sarmiento-Franco et al. (2003) and Donkoh et al. (1999), however, the
nitrogen content of 3.42% compared favourably with that in predominant browse legume leaves inWestAfrica, notably,
Leucaena leucocephala (3.58%), Gliricidia sepium (3.68%) and Sesbania grandiflora (3.76%) surveyed by Smith (1992). The nitrogen content of the F. exasperata leaves in the present study (3.1%) also seemed higher than the 1.96% reported
