dc.description.abstract | Fifteen yearling goats weighing an average 18.7 kg were used to evaluate the potential of
Zizyphus spina-christi leaves as supplement to growing goats fed on Cynodon dacty/on
grass, in Cheleka catchments. South Wello, Ethiopia. Animals were randomly assigned to
five feeding treatments and individually stall-fed for a preliminary period of 14 days. This
was followed by 14 days of feeding to determine dry matter intake and digestibility. and a
3-month of feeding to determine body weight change. The treatments were formulated
based on leaves: grass ratios of: 0: 100, 25:75. 50:50. 75:25 and 100:0% referred as
treatments. I. II. III. IV. and V. respectively. Completely randomized design (CRD) and
General Statistical (Gensat) package was used during the experiment and analysis of
data. Leaf biomass of Zizyphus spina-christi was quantified using crown covers and stem
diameters as independent variables.
The nutritional characteristics of Zizyphus spina-christi leaves and Cynodon dacty/on grass
were determined and the Zizyphus spina-christi leaves showed higher crude protein and
lower fibre content. Daily dry matter intake. digestibility and body weight gain increased (P
< 0.05) with increase in level of supplementary diet of Zizyphus spina-christi leaves.
However, there were no significant differences (P>O.05) between treatment IV and V on
intake, digestibility and body weight gain.
Thus, Zizyphus spina-christi leaves is a potential feed supplement to growing goat fed on
Cynodon dactylon grass in the dry season, as the dry season grasses are deficient in the
required nutrients and cannot meet goat's requirements. From existing data of leaf
biomass and nutritional values of Zizyphus spina-christi leaves, it could be therefore
concluded that its leaves could replace conventional supplements, which are expensive
and not easily available locally to provide protein supplements for growing ruminants like
goats. This would reduce some of the major feed | en |
