Acacia villosa is a leguminous tree in the family of Mimosoideae. It was introduced to Indonesia in 1920 from Curacao (West Indies) and now widely grows in Indonesia especially in the buffering zone of forest area. Acacia villosa may be potential as a protein source as its protein content is quite high (22-28%). However, addition of different extracts from Acacia villosa to in vitro fermentation showed a significant inhibition of these extracts to dry matter digestibility of elephant grass and protein digestibility of casein. Methanol extract gave the highest inhibition compared to 50% methanol or water extracts. The inhibition was greater to fibre than protein digestibility and more significant to rumen microbes than to microbial enzyme. The in vivo test on sheep without adaptation period showed 75% mortality in a week. There were several anti nutritive compounds measured in Acacia villosa but suspected one or more toxic compounds which are polar compounds need to be clarified and identified.
