The major limitation to ruminant production in many tropical regions of Africa, Asia and Australia is poor nutrition. Annual growth rates of animals are restricted by the low nitrogen and high fiber content of the native grasses and crop residues that form the basis of the diets in these regions....

Rumen microbial responses to antinutritive factors in fodder trees and shrub legumes
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...

Ameliorating the toxic effects of Acacia angustissima with polyethylene glycol in rats
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...

In vitro screening of rumen fluid samples from indigenous African ruminants provides for rumen fluid with superior capacities to digest tannin-rich fodders
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 ...
