Summary
Salinomycin poisoning in horses caused severe clinical signs and hindlimb paralysis. This faulty feed concentrate led to high mortality rates, with only six of 24 horses surviving.
Area of Science:
- Veterinary Toxicology
- Equine Medicine
- Animal Nutrition
Context:
- Recent outbreak of salinomycin poisoning in 24 riding horses in Silesia.
- Horses were fed a concentrate with 61 mg/kg salinomycin due to manufacturing error.
- Each horse consumed 2-3 kg of contaminated feed.
Purpose:
- To discuss the clinical and laboratory findings of salinomycin poisoning in horses.
- To analyze the effects of a specific faulty feed concentrate on equine health.
- To document the outcomes and mortality associated with this poisoning event.
Summary:
- All 24 horses exhibited severe intoxication signs, notably hindlimb paralysis.
- Laboratory results showed elevated liver enzymes (ASAT, ALAT, AP) and alkalosis.
- Mortality was high, with 18 horses dying or being euthanized within days; only 6 survived.
Impact:
- Highlights the critical importance of accurate feed formulation and quality control in animal nutrition.
- Provides valuable data on the clinical presentation and diagnostic markers of salinomycin toxicity in horses.
- Underscores the severe consequences of ionophore antibiotic contamination in equine feed.
