Six-week-old wheat seedlings (Triticum aestivum) grown in pots with an alfisol soil with vertic properties and mulched at a rate equivalent to 10 t ha-1 with leaf prunings of Grevillea robusta, Erythrina abyssinica. Gliricidia sepium, Albizia schimperiana, Acacia nilotica, Acacia polyacantha, Leu...

This study sought to determine if sheep suffer neurological symptoms when fed Acacia angustissima leaves, and whether an equivalent amount of 70% acetone extract would have the same effect. In addition, the study tried to determine if treatment of leaves with 70% acetone would destroy the activit...

A digestibility trial was conducted with the objectives to evaluate the effects of supplementing single or mixtures of selected MPTs or wheat bran on feed intake, digestibility, and passage rate in Menz sheep offered a basal feed of tef (Eragrostis tef) straw. The study was conducted using 36 mal...

Tannins limit the use of fodder trees as feed for ruminants. Removal of the effects of tannins would thus improve the nutritional quality of these trees. This prompted the study to evaluate the effect of rumen or faecal mixed cultures from different animals on tannin degradation. Tannin extracts,...

A 90-day growth trial was designed to compare the performance of calves on 3 dry-season diets composed of local resources from the Borana pastoral system. The control group received the traditional diet of cut- and carry, standing - brown grass while the other diets consisted of grass hay stored ...

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...

Exmines the nutritive value of fruits from Acacia tortilis, A. albida, A. nilotica and A. sieberiana. Compares the fruits of these four species with the meal produced by industrial extraction of oil from noug (Guizotia abyssinica). Also compares these feeds as sources of protein when offered in c...

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...
