Place one implant subcutaneously in the neck of a mare that has been determined by rectal palpation and/or ultrasonography to have an ovarian follicle greater than 30 mm in diameter.

Select the implant site by locating an area of the neck midway between the head and shoulder. Prepare the implantation site by thoroughly cleaning the skin with an appropriate disinfectant. Insert the entire length of the needle subcutaneously and fully depress the syringe plunger. Slowly withdraw the needle while pressing the skin at the insertion site. Examine the syringe and needle to ascertain that the implant has not remained within the syringe or needle. It may be possible to palpate the implant in situ.

Do not attempt to re-use the implanter.

The biocompatible implant is absorbed and does not require removal.
