3. Results and discussion
The results of the chemical composition of the supplement rations and grazed forages are given in Tables 2 and 3. The crude protein (CP) content of the energy-based rations systematically from 18.6 in ration to 11.4% in ration 5. Ration 6 being decreased primarily a protein supplement contained 23.5% CP. The NDF. ADFEE and ash of the supplement did not show any definite trends The herbaceous plants and shrub legumes contained more CP than the grasses. While the grasses contained between 4.9 and 7.6% CP, the CP in the other plant species except for Aspilia africana, ranged from 7.1 to 15.9% The inventory of the plant species in the grazed paddock is also shown in Table 3 Most of the moderately to highly palatable species were of the family. Papilionaceae Serophulari- Caesalpiniaceae. The species in the Composite, Rubiaceae, Tiliaceae, aceae and Sterculiaceae were mostly of low acceptability in the forage value rating The grazed natural pastures were relatively high in CP content because most of the species were in the vegetative stage. Higher cP contents and digestibility have been associated with pasture species during this stage compared with the flowering/seeding Furthermore. the growth of the species was enhanced by the amount of rainfall stage. (742.7 mm) during the experimental period. Preference for the leaf by grazing animals was higher than for the stem part (Weir and Torre 1959. This was attributed partly to the higher CP content of the leaf over other parts of and the whole plant (Henzell and oxenham. 1964: Mears and Humphreys 1974) In this study, the mean cr content of the whole plant of most species was above 7.0%. thus it could be inferred that the performance of the goats were not limited by the protein content of the herbage
