title: [Animal nutrition for veterinarians--recent cases of clinical disorders in horses after intake of ionophore-containing feed].
abstract: Anamnesis and clinical signs of horses form five different stables after ingestion of ionophores are reported and techniques of feed examination are described. Within a few hours or days after feeding of new types or batches of concentrates horses fell ill. They showed colic-like symptoms with intense sweating and ataxia. Most of the sick animals died within a short time span. Samples of the concentrates were analysed and different types and amounts of ionophores were detected. In four cases contamination by monensin in concentrations of less than 5 mg to 679 mg/kg feed were found. One feed sample contained monensin (8.8 mg/kg feed) as well as salinomycin (67.3 mg/kg feed). In one case lasalocid (7.9 mg/kg feed) was present. One horse from the stable where animals had obtained concentrates containing monensin (679 mg/kg feed) was necropsied. Typical signs of monensin intoxication with severe myocardial degeneration were found. Veterinarians should be alert to this rare but severe intoxication of horses.
