Lutalyse Injection

Lutalyse from Zoetis is a luteolytic agent used to manipulate the equine and cow heat cycles. Lutalyse can be used on cattle, swine, and mares. 

Speak to your veterinarian about dosage. Zoetis recommends an intramuscular injection of 1mg (1mL to 2mL with solution) per 100lbs bodyweight. 

Reactions to Lutalyse usually occur within 15 minutes of injection and can include lying down, incoordination, abdominal pain, increased respiration, and increased heart rate.
