The cyanogenic plants are responsible for most cases of poisoning in farm animals, mainly cattle and small ruminants, being less frequent in horses due to the high selectivity food and non-use of derivatives of cassava in the feed species. This paper reports with unprecedented intoxication three horses Mangalarga Marchador by Manihot esculenta (manioc) offered to the animals under confinement, which after continuous intake, had followed colic syndrome and clinical signs consistent with poisoning by cyanogenic plants, succeeding clinical treatment using support associated with sodium thiosulfate intravenously.
