Experimental Ferula communis (giant fennel) Toxicosis in Sheep

Abstract: Summary The effect of feeding 0.25, 0.5, 1.0, 2.5 or 5.0 g of the anticoagulant plant Ferula communis (giant fennel)/kg body mass/day to Merino lambs was studied. Dosages up to 1.0 mg/kg/day for up to 5 weeks caused slight increases in the prothrombin time (PT) test, but failed to induce signs of ill‐health, as judged by blood tests. At 2.5 or 5.0 g/kg/day, levels of PT were considerably higher, and disturbances in blood clotting were evident, as manifested by internal hemorrhage and failure of bleeding wounds… Show more

“…Nevertheless, susceptibility to ferulenol can be qualified to be similar between rat and farm animals. This result is coherent with published studies showing that repeated administration of ferulenol was able to lead to increase in prothrombin time and in reduction of pool of vitamin Kdependent clotting factors (Aragno et al, 1988, Fraigui et al, 2001Shlosberg et al, 1985;Tagliapietra et al, 1989).…”

“…Nevertheless, few studies allowing to prove the role of ferulenol and/or ferprenin in "ferulosis" are available. The involvement of ferulenol in the hemorrhagic syndrome was shown by in vivo studies in rats (Aragno et al, 1988, Fraigui et al, 2001, Fraigui et al, 2002, Lamnaouer et al, 1991Tagliapietra et al, 1989), mice (Fraigui et al, 2001, Fraigui et al, 2002, sheep (Lamnaouer et al, 1990;Otieno et al, 1979;Shlosberg et al, 1985) and lamb (Egber et al, 1998). Nevertheless, the mechanism was not described, except that consumption of ferulenol was associated to decrease in vitamin Kdependent clotting factors.…”

“…3 4 The toxic activity of giant fennel is characterised by a fatal haemorrhagic syndrome due to an inhibition of blood clotting. 5 6 This intoxication affected many animal species, mainly sheep, 7 cattle, 2 horse, 8 pig, 9 rabbit, 9 rats 10 and mice. 11 Even humans may be affected following an uncontrolled traditional therapy with Ferula extract.…”

“…Elle est peu étudiée en Algérie bien que la première description de l'intoxication, « le férulisme », ait été faite par une équipe de l'Institut Pasteur d'Alger (12,55). Alors que son feuillage et ses tiges verdoyantes parsèment les pâturages, les animaux évitent de la consommer : ils le font lorsque plus aucun autre fourrage n'est disponible (49).…”

“…Les seules lésions post mortem observées ont été une congestion généralisée et d'importantes hémorragies avec hémothorax, hémopéritoine, hématomes et suffusions sous-cutanées. Ces signes cliniques et ces lésions ont également été rapportés par d'autres auteurs(14,49). Caractéristiques Thapsia garganica est une plante vivace, de la famille des Apiaceae (ombellifères), à tige florifère dressée, peu ramifiée, haute environ de 1,50 m. Elle a de grandes feuilles en touffe, très découpées, à divisions linéaires, pourvues d'un pétiole en gaine à la base.…”
