Artificial Insemination

Artificial insemination for horses has been around for decades. It was used initially for mares or stallions with injuries that could not physically breed or for stallions booked for a large number of mares. Now its use has expanded to include breeding horses across the country with shipped semen. Learn how to artificially inseminate a mare by following these steps.


Difficulty: Moderately Challenging

Things You’ll Need:

  Stored horse semen
  Ovulating mare
  Iodine solution
  Sterile cotton swabs
  Insemination pipette
  Trail wrap
  Breeding stocks
  Sterile lubricated arm glove

Step 1:

Have a veterinarian perform a general health check and reproductive examination on the mare. She should also be vaccinated and have her teeth checked.

Step 2:

Ensure that the mare is in the proper stage of the heat cycle to be bred. She must be ovulating for the semen to take and for a pregnancy to begin. If a stallion is not available to "tease" the mare, your veterinarian may palpate her every other day to check for ovulation.

Step 3:

Wrap the mare's tail completely and secure it to one side during the entire insemination process. Contamination of the perineal area can be detrimental to the health of the mare and the pregnancy.

Step 4:

Put the mare into a set of breeding stocks. This will allow you to work on the mare without fear of her moving around or kicking out, possibly injuring you or herself.

Step 5:

Scrub the perineal area with an iodine solution, such as Betadine. Use a sterile cotton swab and start at the center, working outward. Repeat this step at least twice, using a new swab each time. Carefully remove all of the iodine solution so that it doesn't enter the vaginal canal.

Step 6:

Remove the semen from the container through an insemination pipette and syringe. Avoid touching the pipette as this can cause contamination.

Step 7:

Use a sterile lubricated arm glove on one arm. Hold the pipette with your thumb covering the end, and hold the attached syringe in the other hand. Keep the end of the pipette covered so it does not touch the mare until it reaches the uterus.

Step 8:

Insert your arm into the mare's vagina. Reach the cervix to find the opening of the uterus in the center. Slide the pipette into the uterus, guiding the end of it with your finger. Forcing the pipette can cause damage.

Step 9:

Introduce the semen into the uterus once the pipette cannot be inserted any further. Once all of the semen is in the uterus, slowly remove the pipette from the mare's vagina.
