Abstract

Four browse legume foliages (leaves and pod fruits) from three species of Acacia (A. polyacantha, A. tortilis, A. nilotica) and Dichrostachys sp. native to Tanzania were evaluated for nutritive potential to establish levels and effect of normal phenolics and tannins antinutritive factors (ANFs) on in vitro feed digestibility (IVD). Total extractable phenotics (TP), tannins (TT) were estimated by Folin-Ciocalteu assay, and condensed tannins (CT) by butanol/HCl assay. In leaves, total proanthocyanidins were assayed into constituent anthocyanidins' flavonoids by high performance liquid chromatography (HPLC). Organic matter degradability (OMD) was estimated in vitro by gas production technique. Adverse effects of tannin's ANF on IVD were assessed by polyethylene glycol (PEG) tannin bioassay. Crude protein (CP) varied (P
