Abstract

Intake, growth and carcass yield of indigenous goats fed basal diets of market wastes of sweet potato (Ipomoea batatas) vines (SPV) and scarlet eggplant (Solanum aethiopicum) (SEP) were examined in two experiments. In experiment I, the effect of presentation method (chopping, hanging or adding molasses) on the intake of SEP and SPV was evaluated. Presentation method did not influence the intake of SPV while hanging resulted in the highest (P < 0.05) intake of SEP. In experiment II, 24 male growing goats were supplemented with a concentrate (25% cottonseed cake +75% maize bran) in four dietary groups: SEPD, SPVD, SEP+SPV and Control where elephant grass (Pennisetum purpureum) was offered as the roughage. SEP were offered by hanging, while SPV were chopped. The goats were slaughtered after 12 weeks of feeding. Goats in the SEPD group constantly lost weight, hence were not followed to the end. Average daily gain and hot carcass weight were highest (P < 0.05) in the SPVD group (44 g/d and 8.4 kg, respectively), but similar between the SEP+SPV (19 and 6.8) and Control (21 and 6.9) groups. In conclusion, SPV can support goat meat production where standard feed resources are scarce when fed with an energy-protein concentrate. SEP are poorly consumed by goats, hence cannot be used as their sole basal feed.
