Influence des substances polyphenoliques sur la valeur nutritive des fourrages ligneux: Synthese de recherches menees par le CIPEA
Presents findings of a study conducted to determine changes in feed intake and utilization by oxen during work, comparing estimated energy balance and liveweight change in local zebu and crossbreds. Also assesses breed effects on water intake, feed intake and utilization.
The effect two East African browses, A. brevispica and S. sesban, on feed digestibility and palatability were described. The browses were fed at three levels of each in combination with vetch (Vicia dasycarpa) and teff straw (Eragrostis abyssinica) in a Latin Square design to sheep and goats. Tef...

Investigates the nutritive value of three important native forages in southern Ethiopia (two browses and one cultivated legume) for possible inclusion in improved feeding systems for calves managed by seminomadic pastoralists. Fruits (pods & seeds) of Acacia tortilis (Forsk.) Hayne subsspirocarpa...

We described the effects of two East African browses, Acacia brevispica and Sesbania sesban, on nitrogen metabolism of sheep and goats. The A. brevispica had a substantial amount of proanthocyanidins (condensed tannins); S. sesban did not. The browses were fed at three levels in combination with ...

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...
