Abstract
The report of ophidic accidents in grazing animals is very low, and it is also widely under recorded. In spite of this, it is of great use to know the incidence of these accidents, as they are very important due to the economic loss they may cause to the livestock sector. Accidents caused by poisonous snakes from the <em>Viperidae</em> and <em>Elapidae</em> families in horses and in cattle are very frequent in many parts of the world, given the increase in land destination for livestock. Colombia’s case is no different; however, the report of this type of accidents is very low. In the different reports of ophidic accidents in animals, it is observed that the main systemic manifestations are characterized by cardiac, hemodynamic and neurotoxic complications. Likewise, local effects are observed, mainly characterized by the presence of local bleeding, edema and necrosis. The specific treatment used in accidents caused by snakes is serotherapy, which consists of full or fractional immunoglobulin G (IgG Serum) (Fabotherapics Fab or Fab<sub>2</sub>), specific for a gender or a species.
