Stable Management Podcast 46: Solving Common Broodmare Problems with Dr. Carleigh Fedorka

In this episode of the Stable Management Podcast, host Haley Peffer sits down with Dr. Carleigh Fedorka from Colorado State University to tackle common broodmare problems, with a focus on endometritis—the leading cause of subfertility in mares. Dr. Fedorka explains that endometritis, characterized by uterine inflammation, affects 15–25% of mares and can stem from multiple factors including age, poor perineal conformation, PPID, equine metabolic syndrome, and even 'sleeper mares' with no obvious risk factors. She emphasizes the importance of proactive management, including pre-breeding soundness exams, rectal ultrasounds, endometrial cultures, cytology, and advanced diagnostics like low-volume lavage and endometrial biopsies. Nutrition plays a key role too, with recommendations to avoid both under- and overfeeding, and to consider evidence-backed supplements like L-carnitine and resveratrol. The episode also explores emerging treatments such as ozone therapy, kerosene (used cautiously for fibrosis), and biologics like platelet-rich plasma and MCWF, which offer antimicrobial and anti-inflammatory benefits without contributing to antibiotic resistance. Dr. Fedorka concludes with a strong endorsement of partnering with a board-certified theriogenologist to maximize reproductive success. Key takeaways include: (1) Proactively diagnose and treat mares with endometritis using advanced diagnostics; (2) Prioritize a trusted reproductive specialist (theriogenologist) over general practitioners; (3) Use evidence-based supplements like L-carnitine and resveratrol; (4) Avoid feeding inadequate rations—test hay and work with a nutritionist; (5) Consider embryo transfer or IVF for mares with severely compromised uterine health; (6) Re-evaluate fear-based reactions to treatments like kerosene with scientific scrutiny; (7) Monitor estrus timing and breeding protocols closely; and (8) Invest in a comprehensive pre-breeding workup in the fall to avoid repeating failed cycles.
