Ionophore Toxicity in Horses
Signs of Ionophore Toxicity
Severity and speed of onset of clinical signs depends on how much they ingest. Horses with a common feed source can be affected simultaneously.
▪ Sudden death
▪ Exercise intolerance
▪ Feed refusal
▪ Colic
▪ Increased heart/respiratory distress
▪ Hypotensive shock.
Note: If the horse survives, it will likely have some level of permanent damage to heart muscle, possibly leading to poor performance and congestive heart failure.
