The Calotropis procera has been an alternative feed for the ruminants in the brasilian semiarid region, presenting fast establishment and constant availability of fitomassa, until 3.0 t of DM/cut, in the dry season. On the aspect biochemical studies have detected various active substances as cardiac glycosides, non enzymatic proteins and enzimatics proteins, that can cause toxicity in animals when inserted in their diet. In nutritional terms, this species provides important nutrients with emphasis on protein, average value of 20%, and in vitro digestibility above 70%. It researches they showed that the intake of C. procera by goats and sheep in the form in nature can cause deaths, however, to make the process of hay and silage the toxicological effects are reduced. The utilization of C. procera is promissing, needing studies for maximize of the productivity; biochemical evaluation for identification of active substances, their mechanisms and local action in the animal, as well as testing to obtain the safe levels for inclusion in various forms of supply (in natura, hay and silage).
