E-mail: [e-mail] An acute disease characterized by colic and timpanism was reported in Pará and Rondônia after horses fed with Panicum maximum cultivars Momba- ça, Tanzânia and Massai pasture grazing. In this study an acute abdomen case was experimentally reproduced after the ingestion of Panicum maximum var Massai pasture based on twenty two clinic and surgical cases of acute timpanic colic cases reported in a farm in the city of Cuiabá – MT, fed with Panicum maximum var Massai pasture, confirming the etiology and accompanying the clinical evolution of the disease. A horse kept in a stall fed only with Massai pasture was daily evaluated and it was verified that the animal presented as result a clinic perfil of pain, high cardiac frequency, respiratory difficulty, intestinal motility absence and exaggerated distention of the stomach and bowels by gas, seeing during the necropsy the stomach and bowels fully distended by gas with liquefied content except by small colon where the feces presented dry and with mucus characterizing the intestinal atony. The necessity of studies that search the identification of the agent responsible for the intestinal atony and gas accumulation in horses fed with Panicum maximum is exposed.
