ABSTRACT: This study evaluated the nutritional value of pelleted supplements based on four major feed
resources fed to small ruminants by smallholder farmers in the Accra Plains. Leaves of Samanea saman, Acacia
auriculiformis and Ficus exasperata, and cassava peels were dried, milled, mixed with other ingredients and
pelleted to form Samanea saman (SS-S), Acacia auriculiformis (AA-S), Ficus exasperata (FE-S) and cassava peel
(CP-S) based supplements. The supplements were fed to twenty West African Dwarf goats on a basal diet of
Andropogon gayanus (Gamba grass) hay in a completely randomised design experiment. Voluntary intake of dry
matter did not differ (P>0.05) by the type of supplement. However, crude protein intake was higher (P<0.05) in
goats fed FE-S than those fed CP-S. Acid detergent fibre intake was higher (P<0.05) for SS-S, AA-S and FE-S than
CP-S. Digestibility of dry matter, organic matter, crude protein, acid detergent fibre and neutral detergent fibre
were lowest (P<0.05) for goats on CP-S. Average daily weight gain and Feed conversion ratio were not affected
(P>0.05) by dietary treatments. Also, dietary treatment did not affect (P>0.05) the concentrations
haematological and blood biochemical constituents determined except urea which was higher (P<0.05) in goats
fed SS-S than the other treatments. In conclusion, the above results suggest that browse-based and cassava
peel-based supplements could be fed to confined goats on roughage diets especially in the dry season without
any deleterious effects on intake, growth and physiology of goats.

Small ruminant production is a major livelihood diversification strategy among smallholder farmers in Ghana. Often,
animals are grazed extensively on natural pasture with little or no feed supplementation coupled with minimal health
now compelling many small ruminant keepers to fully or partially confine their animals. Feeding of confined small
ruminants is often inadequate and such animals perform less than their free-roaming counterparts (Baah et al., 2012).
The challenges associated with confinement in the cropping season, coupled with the scarcity of quality feed during the
dry season severely constrain small ruminant production in Ghana (Adjorlolo et al., 2016) affecting income generation.
Slow growth rate, unstable weight gains, lowered resistance to diseases and reproductive problems of small ruminants
feed which can supply substantial amounts of dietary energy, protein and minerals would be an important step in
enhancing the productivity of ruminants in Ghana.
based diets and cassava peel meal- based diet as supplements to West African Dwarf sheep fed on a basal diet of
Andropogon gayanus (Gamba grass) hay and concluded that they were acceptable to sheep and could help improve
performance on low quality forages.
Currently, there is lack of information on the utilization of browse-based pelleted feed supplements on the growth
and physiology of the West African Dwarf goat the most popular goat breed in Ghana. This study therefore evaluated the
effects of pelleted Samanea saman (SS-S), Acacia auriculiformis (AA-S), Ficus exasperata (FE-S) and cassava peel-based
