Alterações reprodutivas em pequenos ruminantes pela ingestão experimental de Poincianella pyramidalis e Amorimia septentrionalis e eliminação de fitotoxinas pelo leite.

Abstract

Aiming to determine the effects of Poincianella pyramidalis on sheep reproduction; confirm the elimination, by milk, of sodium monofluoroacetate and revise about the main phytotoxins eliminated by milk, this thesis is composed of three articles. The ingestion effects of Poincianella pyramidalis by pregnant sheep are described in chapter one. The consumption of this plant during gestation resulted in embryotoxic, abortive and teratogenic effects to this animal species. In the second chapter, it was studied the possibility of elimination of sodium monofluoroacetate by the milk of breastfeeding female sheep, proving that, when consumed during gestation, this toxic active principle causes death in pups if they consume the colostrum after birth. The third chapter is a bibliographic review, in which are presented the main phytotoxins eliminated by milk and that cause intoxication in animals and/or humans that consume it.
