Below are videos of horses that were administered cobalt chloride salts at levels believed to be used on racehorses. This was done for research purposes into potential health and performance effects of the use of cobalt salts in horses. Similar reactions occurred with each administration of cobalt salts. The videos below are disturbing, which is the reason they are posted. Cobalt is not just a doping issue, but it is an animal welfare issue as well. Veterinarians report adverse reactions to cobalt administration are common and the dosage of cobalt administered to these horses is within the dosage range that has been reported as being used by veterinarians and other sources. The horses were carefully monitored during and after the cobalt administration. All recovered within several hours and did not require medical intervention. The study protocol, including adverse reaction response, was approved by the relevant Institutional Animal Care and Use Committee.
