Barbosa J.D., Oliveira C.M.C., Duarte M.D., Peixoto P.V. & Tokarnia C.H. 2005. [Experimental and natural poisoning by Ipomoea asarifolia (Convolvulaceae) in buffaloes and other ruminants.] Intoxicações experimental e natural por Ipomoea asarifolia (Convolvulaceae) em búfalos e outros ruminantes. Pesquisa Veterinária Brasileira 25(4):231-234. Escola de Medicina Veterinária, Campus Castanhal, Universidade Federal do Pará, Rua Maximino Porpino 1000, Castanhal, PA 68743-080, Brazil. E-mail: tokarnia@ufrrj.br Ipomoea asarifolia R. et Schult. is a plant responsible for occasional outbreaks of poisoning in cattle, sheep and goats. Its oral administration to cattle and buffalos showed that the buffalo is as susceptible as cattle. One to 4 daily doses of 10-20g/kg caused similar symptoms in both species, as incoordination, muscular twiching and swaying of the head and anterior part of the body (pendular movement). In buffaloes the signs of incoordination were observed to a smaller extent. There is no report yet on natural poisoning by I. asarifolia in buffaloes, possibly because cases are not being noticed.

• Poisonous plants Ipomoea asarifolia Convolvulaceae plant poisoning buffaloes bovines sheep goats.
