The Broodmare Breeding Soundness Exam: What to Discuss Before Breeding Season
The stallion contract is ready, the collection schedule is posted, and you have a preferred foaling window in mind.
Before those decisions lock you into a timetable, schedule the mare’s breeding soundness examination.
A productive appointment should help you understand her current reproductive condition and turn the findings into a workable plan for the season.
Start with the records
Prepare a season-by-season history if one is available.
Include breeding dates and methods, semen information, pregnancy checks, losses, foaling outcomes, and previous treatments. Bring laboratory reports rather than relying only on descriptions such as “she needed cleaning out.”
For a mare that failed to conceive, distinguish between unsuccessful breedings and pregnancies that were established and subsequently lost.
A calendar or spreadsheet can make the sequence easier to follow and expose gaps worth discussing.
Ask what examination this mare needs
A young maiden mare, a mare recently foaled, and a mare returning after an unsuccessful season may require different evaluations.
Depending on her history and findings, the examination can include assessment of external reproductive anatomy, palpation and ultrasound, examination of the vagina and cervix, and uterine sampling. Merck outlines how the breeding soundness examination varies with the mare’s circumstances.
Tell the veterinarian if she could already be pregnant. Pregnancy status must be established before procedures that could disrupt an existing pregnancy.
Understand what the samples answer
Culture, cytology, and biopsy provide different information.
Culture investigates microorganisms in the sample. Cytology examines cells for evidence such as inflammation. Biopsy evaluates uterine tissue and can contribute to a reproductive prognosis.
Ask how the results will be interpreted together and whether cycle stage, recent breeding, foaling, or treatment could affect interpretation. Merck discusses these considerations in its examination guidance.
Useful follow-up questions are:
- What finding prompted this test?
- Does the result require treatment or more investigation?
- How will we assess the response?
- What needs to happen before breeding proceeds?
Match the veterinary plan to the breeding arrangements
Tell the veterinarian whether you are considering live cover, cooled shipped semen, frozen semen, or embryo production.
Discuss the stallion’s availability, shipping arrangements, where the mare will stay, and who can authorize additional work. If a specialist or receiving clinic is involved, establish who is responsible for each stage.
Ask for a realistic estimate that separates the initial examination from monitoring, laboratory work, treatment, and pregnancy checks.
These details help prevent a workable medical plan from becoming an unworkable logistical one.
Leave with the next decisions in writing
Before the appointment ends, clarify:
- Whether the mare is ready to proceed.
- Which findings need attention first.
- When she should be rechecked.
- Who to contact about semen timing.
- When pregnancy examinations will be scheduled.
- What would trigger a change in the plan.
If you are purchasing a broodmare prospect, arrange the reproductive assessment specifically. A routine pre-purchase examination does not automatically include a full breeding soundness examination. Merck makes this distinction in its pre-purchase guidance.
The value of the appointment lies in understanding the findings and knowing what happens next.
