ABSTRACT.- Nóbrega Jr J.E., Riet-Correa F., Medeiros R.M.T. & Dantas A.F.M. 2006. [Poisoning by Sorghum halepense (Poaceae) in cattle in the Brazilian semiarid.] Intoxicação por Sorghum halepense em bovinos no semi-árido. Pesquisa Veterinária Brasileira 26(4):201-204. Hospital Veterinário, CSTR, Universidade Federal de Campina Grande, Campus de Patos, 58700-000 Patos, PB, Brazil. E-mail: franklin.riet@pesquisador.com.br An outbreak of poisoning by Sorghum halepense (L.) Pers. in cattle in the Brazilian semiarid is reported. Nine cattle were introduced 15 days after the first rains into a paddock where the plant was sprouting and had 25-30cm high. Clinical signs of dyspnea, anxiety, muscular tremors and incoordination appeared 15 minutes after the animals began to graze. Two of them died within about 3 hours. The others recovered. Cyanotic mucosa, dark muscles, lung edema and hemorrhages, and leaves of the plant in the rumen were observed at necropsy. The plant was positive for the picrosodic paper test. S. halepense from another farm of occurrence of the poisoning was transplanted into two pots. The picrosodic paper test was performed fortnightly in the plants growing in one of them. The plant was positive for cyanide in all growth stages; during the first 45 days the test was positive within 1 minute, but after day 60 within 3 minutes. Thirty days after the plant had been transplanted into one of the pots, it was administered to a goat at a dose of 11.8g/kg, causing clinical signs of HCN poisoning. The animal recovered after the intravenous administration of 5mL/10kg body weight of a 20% sodium thiosulfate solution. In the Brazilian semiarid S. halepense is frequently found invading the border of ponds and irrigated crops, and is used as forage during the dry season.
