    Ameliorative effects of Ficus and Harrisonia diets on Small East African goat meat yield
    (Small Ruminant Research, 2017) Kalule Nampanzira, Dorothy; Kabasa, John David; Bakyusa Katongole, Constantine; Okello, Sam; Tabuti, John Robert Stephen
    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 < 0.05) by supplementation with the browse foliages. The total DM and CP intakes were highest (P < 0.05) for FM (572 and 91 g/day, respectively) and FHM (638 and 102 g/day, respectively). Compared with the control, supplementation with browse foliages increased (P < 0.05) the average daily gain, hot carcass weight and dressing percentage by up to 37.2, 2.3 and 6%, respectively. Average daily gain was 17, 34, 45, 52 and 54 g/ day for control, CM, FM, HM and FHM, respectively. The hot carcass weight was 6.9, 8.2, 8.8, 9.1 and 9.2 kg for control, CM, FM, HM and FHM, respectively. In conclusion, 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.

    Natural gastro properties of ficus natalensis, Rhuss natalensis and Harrisonia abyssinica in native east african goats
    (Livestock Science, 2016) Kalule Nampanzira, Dorothy; Kabasa, John David; Bakyusa Katongole, Constantine; Okello, Sam; Tabuti, John Robert Stephen
    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<0.05) across the three browse species. The CP a, b, PD and ED fractions differed significantly (P<0.05) across the three browse species. The CP c fraction was similar across the browse species. The NDF a, b, PD, and ED fractions differed significantly (P<0.05) across the browse species. The NDF c fraction was not different across the browse species. In conclusion, Rhuss natalensis subsp. romantica has inferior rumen degradability properties, an indication of low nutritive value for goats 30 compared to Harrisonia abyssinica subsp. abyssinica and Ficus natalensis subsp. Natalensis.
