Mare breeding management

On-farm breeding management for mares being bred with cooled transported semen. Care may include review of breeding and foaling history, pre-breeding reproductive assessment, serial transrectal ultrasonography to follow follicular development and uterine changes, cycle management when appropriate, coordination with the stallion station or semen distributor, artificial insemination, post-breeding reassessment when indicated, and ultrasonographic pregnancy examinations.

Contact us before the breeding season or before the intended cycle—ideally before semen is ordered. We need the mare’s age, reproductive history, previous breeding results, current cycle information, chosen stallion, collection days, shipping method and the semen provider’s requirements. Older, barren or maiden mares, mares with irregular cycles, and mares with previous fluid accumulation or difficulty conceiving benefit from an early planning conversation.

Breeding with cooled transported semen is a coordinated process rather than a single appointment. Most mares require more than one examination so we can assess follicular growth, uterine edema and ovulation status, decide when cycle-management medication is appropriate, and time semen ordering and insemination intelligently. After breeding, we will discuss whether a recheck is indicated and schedule early pregnancy ultrasonography to confirm pregnancy, assess viability and look for twins. No breeding cycle can guarantee conception, and mares with suspected uterine disease or repeated failure may require additional diagnostics or referral.
