Summarises ILCA's findings over several years of research on the nutritive value of browse plants. Discusses nitrogen metabolism in ruminants and tannin chemistry. Examines the effect of browse on animals, i.e., feed intake, growth, digestion of fibre fractions and utilisation of nitrogen. Discus...

The Multi-purpose Tree (MPT) species have the ability to fit into the farming systems of the East African region where low agricultural productivity, widespread land degradation and hence a diminishing capacity to support the growing human and livestock population are major problems. GIS has been...

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....

During the period February to July 1992, the incidence of attacks by insect pests on ten cultivated browse species was studied at Obio Akpa, located in humid southeastern Nigeria. Two of the browse species Gliricidia sepium and Leucaena leucocephala were exotic and eight Alchornia cordifolia, Bap...

Harvests were made at the end of the main (April-August) and minor (September-November) wet, and dry (December-March) seasons for two years. Dry season edible forage samples were analyzed for concentrations of crude protein (CP), neutral detergent fibre (NDF), acid detergent fibre (NDF), acid det...

Browse is an important forage in pastoral systems, especially during dry seasons, because it is high in nitrogen and digestibility. However, browse palatability may be reduced by possible plant defenses such as tannins and physical attributes. Chemical and physical properties of 20 browse species...

Two experiments were conducted using dried leaves of Alchornea cordifolia, Ficus capensis, Manniophytum fulvum and Albizza niopoides. In Experiment 1, dry matter (DM) degradation characteristics were investigated using the in sacco nylon bag technique in West African Dwarf (WAD) sheep, WAD goats ...

Shrubs and trees browsed by Fulani pastoralists' cattle in two areas of central Nigeria were identified by means of interviews with the pastoralists and observations of browsing cattle. Thirty-nine palnt species were identified, many of them indigenous economic trees. The species were ranked by p...
