Elikaei V, Tehrani Sharif, Shahrani H, Rezaeian H, Strychnine doping in race horses., Onl J Vet Res., 27 (9): 523-527, 2023.  Strychnine is toxic with lethal dose 0.5-1mg/kg in dogs, cattle, pigs or horses. Authors report case of strichnine doping of a Turkmen stallion horse 2nd place in races. Horse was kept in stable for urine sampling within 2 hours. Samples were tested by ELIZA for NSAIDS, bases, anabolic and corticoid steroids and strichnine TAO and TA1 tests. The horse tested positive for strychnine without any adverse effects or signs of poisoning suggesting very low doses may enhance performance without inducing toxicity.

Key words : Horse race, Doping, Strychnine, Iran.
