Beta-adrenergic agonist that repartitions nutrients from fat deposition to lean muscle growth. Increases rate of weight gain, improves feed efficiency, and increases carcass leanness.
Not for use in breeding animals. Banned in EU, China, Russia, and many other countries. Use only in finishing animals during the last 28-42 days before slaughter. Handle with caution; may cause tachycardia in humans.
Species-specific contraindications and adverse-reaction reports for swine may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Ractopamine pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in swine — the rules above are the citations specific to this species, not generic recommendations.
