ABSTRACT

In the extensive breeding fields of the northeastern region of Argentina there are abundant vegetals with toxic properties for herbivores, such as “aguapei” or “mandiyura”, which is plentiful in low areas. This study was focused on the effect of intoxication by Ipomoea carnea var. fistulosa on goat´s liver. The intoxication was induced by the administration of leaves and stalks from I. fistulosa to five goats of Creole race of both sexes. Goats were given 50 g/kg/day between 4 and 10 weeks. Four animals with the same characteristics, that did not ingest the plant, constituted the control group. All animals which received I. carnea var. fistulosa as part of their diet, showed typical symptomatology of intoxication induced by this plant. The marker enzymes of hepatic damage increased significantly, in accordance with histopathological lesions in tissue. The control animals did not show abnormalities. It is concluded that the intoxication causes hepatic damage and an acute organic deterioration that led to the death of all the animals.
