The effect of supplements based on Ficus natalensis and Harrisonia abyssinica foliages on intake, growth and carcass yield of tethered goats was assessed on-farm using fourty growing intact male indigenous goats. Five diets were tested, which included the control (tethering on natural pastures), tethering supplemented with molasses (CM) and the three diets whereby tethering was supplemented with molasses as well as F. natalensis and H . abyssinica as follows: Harrisonia ⁄ molasses (HM), Ficus ⁄molasses (FM) and Ficus ⁄ Harrisonia ⁄molasses (FHM). The supplements were formulated to supply crude protein (CP) and energy levels required for an average daily gain of about 50 g/day. Four farms in the same geographical location were used. Each farm had all the five diets with two goats per diet. The goats were tethered during the day (10:00–18:00 h) and the supplements offered overnight (after tethering). The dry matter (DM) intake from tethering ranged between 124 and 162 g/day, and was not affected (P > 0.05) the basal DM intake. However, the total DM and CP intakes were increased (P Ficus natalensis and Harrisonia abyssinica foliages have the potential to be used as low cost protein supplements in low-input goat feeding systems. However, there is need to establish best presentation methods of the browse foliages to the goats.

The natural gastro properties of Ficus natalensis, Rhuss natalensis and Harrisonia abyssinica was evaluated with the objectives of determining the rumen degradation properties. Results showed that H. abyssinica presented the highest DM disappearance from the nylon bags throughout the different incubation times followed by F. natalensis and R. natalensis showed the lowest. The DM readily available soluble fraction (a), insoluble but degradable fraction (b), degradation rate (c), potential degradability (PD) and effective degradability (ED) differed significantly (P
