Nutritional aspects
Rabbits 

No specific information seems available, in the international literature (July 2017), on the direct use of Tephrosia purpurea in rabbit feeding. However, it should be noticed that, in India, the local hare Lepus nigricollis consumed different herbaceous plants, among which Tephrosia purpurea was clearly identified (Prakash et al., 1969). In India, but also in Ghana, Niger or Cameroon, Tephrosia purpurea is used as forage to feed livestock, particularly goats (Bhatta et al., 2002; Calabro et al., 2007; Prabhat et al., 2014; Ziblim et al., 2015). This legume forage, relatively rich in protein (15 to 24% of DM according to the source and the vegetative stage) is appreciated as supplement for grazing animals on poor paddocks (Mbomi et al., 2011). For this reasons, Tephrosia purpurea could certainly be safely used in rabbit feeding, but direct experiments would be welcome. According to the chemical composition of this crude protein rich forage, its calculated digestible energy content is around 7.0-7.5 MJ DE/kg DM but protein digestibility estimation is very low: less than 35% (Lebas, 2016).
