As breeding season approaches, ensuring your broodmare is in peak condition is essential for a successful outcome. Breeding mares requires careful planning, attention to detail, and an understanding of the mare’s unique needs. Below are practical tips to help you create the optimal conditions for a healthy and productive breeding season while highlighting key do’s and don’ts that every mare owner should keep in mind.
The Do’s of Preparing Broodmares for Breeding Season
1. Do Schedule a Pre-Breeding Veterinary Exam
A thorough pre-breeding exam is a cornerstone of preparation for a maiden/barren mare. Your veterinarian will assess the mare’s reproductive health, ensuring there are no underlying conditions that could impede conception or foaling. This exam typically includes:
- Ultrasound: To check the uterus and ovaries for abnormalities.
- Uterine Culture and Cytology: To detect infections or inflammation.
- Overall Health Check: To ensure the mare is in good physical condition.
By identifying and addressing potential issues early, you can improve the likelihood of successful breeding.
2. Do Focus on Optimal Nutrition
A broodmare’s nutritional needs change as breeding season approaches. Proper nutrition is essential for supporting conception, pregnancy, and lactation. Key considerations include:
- Body Condition Score: Aim for a BCS of 5-6 on a 9-point scale. Overweight or underweight mares may experience reduced fertility.
- Balanced Diet: Provide high-quality forage and ensure the mare receives appropriate vitamins and minerals, particularly selenium, vitamin E, and omega-3 fatty acids, which support reproductive health.
- Monitor Protein Levels: A diet with adequate protein is crucial for developing healthy follicles and sustaining pregnancy.
Consulting an equine nutritionist can help fine-tune your mare’s diet to meet her specific needs.
3. Do Provide a Stress-Free Environment
Mares thrive in low-stress environments. Stress can negatively impact hormone levels and reproductive cycles. Create a calm, predictable routine and minimize changes in her surroundings during the breeding season.
- Turnout: Ensure your mare has access to ample turnout in a safe, quiet area.
- Companionship: If possible, house the mare with familiar companions to reduce anxiety.
4. Do Track the Estrous Cycle
Understanding your mare’s estrous cycle is critical for effectively timing breeding attempts. Keep detailed records of her heat cycles, noting behaviors, physical signs, and any patterns. This will help you and your veterinarian pinpoint the ideal window for insemination(in non-thoroughbred cases) or live cover.
The Don’ts of Preparing Broodmares for Breeding Season
1. Don’t Ignore General Health Maintenance
While reproductive health is a priority, it’s equally important to address the mare’s overall well-being. Neglecting routine care can compromise fertility and pregnancy success. Avoid these common pitfalls:
- Skipping Vaccinations and Deworming: Keep your mare’s vaccinations up to date and maintain a deworming schedule. Consult your vet for protocols tailored to pregnant mares.
- Overlooking Hoof Care: Ensure regular trims to avoid discomfort and potential lameness. A healthy mare is more likely to breed successfully.
2. Don’t Overlook the Importance of Light Management
For Thoroughbreds and many other breeds, breeding season aligns with early spring. To encourage mares to cycle earlier in the year, begin managing light exposure in late fall or early winter.
- Artificial Lighting: Provide 16 hours of light daily in the barn or paddock to simulate longer daylight hours.
- Gradual Adjustment: Introduce extended lighting gradually to mimic natural seasonal changes and avoid disrupting the mare’s internal clock.
3. Don’t Wait to Address Past Breeding Issues
If your mare experienced breeding difficulties in the past, such as failed pregnancies or difficulty getting in foal, address these concerns well before the season begins. A proactive approach allows time for diagnostics and treatment, improving the chances of success this year.
4. Don’t Forget to Plan for Foaling
If your mare is already in foal and will be bred back this season, don’t lose sight of her upcoming delivery. Proper foaling preparation ensures both mare and foal remain healthy and ready for the next breeding attempt. Having an expert team to aid in this process is key, as it’s more than just getting the cute, cuddly foal! Foaling entails a lot of preparation and skill.
