Horizon Equine’s Tailored Reproduction Packages for Mares

Every equine breeding endeavor should commence with a clear objective in mind. To assist horse owners in realizing their goals, we’ve tailored cost-effective breeding packages designed to oversee every facet of mare reproductive management.

Our Breeding Packages are cycle-based plans designed to enhance the likelihood of a successful, healthy pregnancy, all while offering valuable savings. These packages provide a choice of two options for artificial insemination, for the use of either fresh cooled or frozen semen.

Take that first important step.  Book a pre-breeding examination for your mare at the onset of breeding season.  Our veterinarian will fully evaluate the mare’s reproductive health and collaborate with you to develop the best plan while ensuring the well-being of both the mare and her future foal.

Can enrolling in a breeding package ensure a pregnancy?

Unfortunately, no. While we’d love to guarantee a pregnancy, it’s impossible to ensure conception on any specific cycle due to various factors.

When does the breeding package start?

Before the breeding package starts, our veterinarian will examine the mare during a pre-breeding examination at the beginning of the breeding season. This examination thoroughly assesses the mare’s reproductive health. If the results are favorable, our vet will work closely with you to establish the most suitable breeding plan for your needs. Purchase of the selected breeding plan then marks the official start of the process.

Are breeding packages refundable in case of unforeseen complications?

In some instances, complications may arise during a breeding cycle, including issues with semen quality, difficulties in obtaining semen, or mare ovulation failures. While our team strives to provide the best service, certain circumstances are beyond our control. Consequently, Breeding Packages are non-refundable once the management of the mare’s estrus cycle has commenced.

Is it possible to keep my mare at home during the breeding package?

Unfortunately, no. Mares participating in the program must be accommodated at our clinic. Please be aware that clinic space is limited, and Breeding Packages are allocated on a first-come, first-served basis.

Is the breeding package comprehensive to cover all my mare’s needs for one heat cycle?

The Breeding Package encompasses all standard procedures for managing one estrus cycle in a fertile mare. However, certain mares may necessitate more extensive laboratory diagnostics or subfertility therapy, which are not part of the Breeding Package. Your veterinarian will evaluate your mare on an individual basis, and any additional recommendations will be reviewed and discussed with you.

Where does the 14-Day pregnancy check occur?

The day-14 pregnancy ultrasound examination is included as part of your package. You have the option to bring your mare to the clinic, or we can perform the check at your location. (additional call fee applies)

What's the process for scheduling semen for AI breeding?

Scheduling semen for AI breeding is a crucial and intricate component of a successful breeding plan. Owners should proactively reach out to stallion owners well in advance to establish collection days for fresh AI plans. When it comes to frozen semen, it must be procured and securely stored at Horizon Equine well in advance of commencing the mare’s breeding package. For those requiring assistance with international semen importation and shipping, Horizon Equine offers support (additional fees apply). Planning is vital, as this task is time sensitive.

Will Horizon Equine provide breeding services if I opt not to enroll in a breeding package?

Absolutely! We’re here to assist with your equine reproductive requirements. Mares not enrolled in a Breeding Package will be billed based on our regular per-visit rates rather than a fixed price per cycle.

At Horizon Equine, we are honoured to have two exceptional veterinarians who focus on the intricacies of equine reproduction and fertility.
