Acacia angustissima is a tropical legume, which has potential as a fodder tree, but contains secondary compounds which have an anti-nutritional effect in ruminants. This study was designed to indicate whether condensed tannins alone are responsible for the anti-nutritional affect or whether non-p...

The effect of Acacia angustissima on rumen fermentation was evaluated. Acacia angustissima was fed to two groups of cannulated Ethiopian highland sheeOne group (three animals) was directly supplemented with 300 g per head day-1 of sun-dried A. angustissima. These animals died after 9 and 21 days ...

Acacia angustissima has potential in agroforestry systems for forage production in tropical environments. However, feeding trials indicate that the leaves are potentially toxic. Signs of toxicity in sheep are similar to those presented by sheep fed flatpea (Lathyrus sylvestris) hay which contains...

In most tropical countries poor nutrition limits ruminant productivity. The main feed resources include native pasture and crop residues, which are low in nitrogen (6.2-10.6 g/kg DM) and high in fibre (676-772 g/kg DM). Nutritional deficiencies of these feeds can be alleviated by supplementation ...

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 ...
