Plain-English summary

A 6-year-old Percheron mare had a nosebleed that lasted for 24 hours. Tests showed her blood wasn't clotting properly, leading to a diagnosis of moldy sweetclover poisoning, which can happen when horses eat spoiled clover. The veterinarian treated her with a blood transfusion and daily vitamin K injections. After this treatment, the mare recovered well and her bleeding stopped.

Abstract

A six year old Percheron mare was presented with a history of spontaneous unilateral epistaxis of 24 hours duration. The blood one stage prothrombin and partial thromboplastin times were markedly prolonged. A diagnosis of moldy sweetclover poisoning was made on the basis of the history and clinical and laboratory findings. A single whole blood transfusion and four daily intravenous injections of vitamin K(3) proved to be a successful treatment.
