Several tannin-tolerant bacteria were isolated from enrichment cultures of rumen microflora of bush duiker, giraffe, Grant's gazelle, sheep, and goat, and established in medium containing crude tannin extracts or tannic acid. The isolates were characterized by classical and molecular methods. The...

Characterization of tannin-tolerant bacterial isolates from East African ruminants
This study evaluates the differences in the gas produced by Sesbania accessions and related gas production to macro-constituents and tannin content of the browse species. Fresh samples were incubated in triplicate in a medium prepared from sieved rumen liquor harvested from two rumen-fistulated c...

The capabilities of rumen fluid sources from indigenous African ruminants and hindgut fluid from zebra to ferment leaves of Acacia angustissima, Calliandra calothyrsus, Leucaena diversifolia, Leucaena leucocephala, Leucaena pallida, and Tephrosia bracteolata were evaluated to determine the presen...

This study was aimed at evaluating (1) the dry matter (DM) and nitrogen (N) degradabilities (by sheep) of Sesbania sesban leaves, Acacia albida (Faidhabia albida), A. siberiana and a. tortilis fruits and (2) the effect of feeding a mixture of oilseed cake and tanniferous browses on the degradabil...

This study evaluated the synergism between oilseed (50:50 noug (Guizotia abyssinica) and groundnut) cake (OSC) and tanniferous feeds (pods of Acacia albida and Sesbania sesban leaves) in two experiments. S. sesban has a lower content of soluble phenolics than A. albida pods (196 vs. 270 g/kg). Di...

Three strains of tannin-tolerant rumen bacteria were isolated from enrichment cultures of rumen microflora of sheep, goat, and antelope and established in medium containing high concentrations of crude tannin extract or tannic acid. These three strains (EAT2, ES3, and EG19), characterized as Sele...
Acacia angustissima has potential as a fodder tree, but was toxic to sheep when fed without adaptation at levels higher than 50 g per day in previous studies. In the present study it was determined that rats are sensitive to anti-nutritional factor(s) of A. angustissima and can therefore be used ...

The experiment was carried out using a replicated (3x3) Latin square design with six sheep, to assess, the effect of supplementing maize stover fed ad libitum at three levels (100, 150 or 200 g) of Leucaena diversifolia. The sheep had an initial live weight of 26.4 kg (+ or -) 1.78 kg. In each pe...
