Pre-Breeding Season Preparations

While it may feel early, the team at Running Springs is already looking ahead to the 2026 foal crop. As Katie Van Slyke explains, the key to success in horse breeding lies in strategic preparation. This includes monitoring the reproductive status of her recipient mares (recip mares), which will carry embryos from her top breeding mares. By aligning the cycles of the donor and recip mares, she maximizes the chances of a successful pregnancy.

Two of Katie's mares, Beyonce and Indy, are set to be bred this season. Additionally, the team conducted an ultrasound on Gracie due to her history of early foaling. At 296 days of gestation, Gracie is progressing well, but caution is essential given her past. By closely monitoring her uterine health and taking baseline blood tests, Katie ensures that every precaution is taken for a healthy foaling.

The Art and Science of Horse Breeding

Horse breeding at Running Springs is both an art and a science. One of the critical decisions involves selecting the right stallion for each mare. For example, Annie, a versatile producer, is being bred to a young stallion known for his all-around performance traits. By matching complementary genetics, Katie aims to produce foals with exceptional versatility and athleticism.

An interesting aspect of Katie's approach is her use of frozen semen. However, breeding with frozen semen presents unique challenges, as the uterine environment is less manipulatable, potentially impacting pregnancy rates. Nevertheless, Katie's strategic planning and close collaboration with her vet help mitigate these challenges, demonstrating her deep understanding of reproductive science.

Embryo Transfers and Advanced Breeding Techniques

Katie Van Slyke is also pioneering advanced breeding techniques at Running Springs, including embryo transfers and ICSI (Intracytoplasmic Sperm Injection). This season, she has an embryo in Texas, awaiting transfer into one of her recip mares. This requires precise timing, as the recip mare must ovulate exactly one day after the donor mare to ensure optimal conditions for implantation.

To synchronize these cycles, Katie meticulously tracks follicular development using ultrasound measurements. For instance, Willow and Charlotte, two recip mares, were examined for follicle growth to determine their suitability as surrogate carriers. By maintaining detailed records and frequent communication with her vet, Katie maximizes the success rate of these advanced breeding techniques.

The Importance of Mare Health and Monitoring

At Running Springs, mare health is paramount. Katie's team conducts thorough examinations, including uterine flushes and cultures, to ensure no underlying infections could compromise pregnancy. For mares like Indy, who is not yet in heat, these pre-breeding health checks are vital for a successful breeding season.

Additionally, Katie uses precise measurements to monitor gestation progress. For Gracie, whose previous foal was born prematurely, Katie is taking no chances. By measuring the combined thickness of the uterus and placenta, she ensures everything remains within normal ranges. This vigilant approach reflects Katie's commitment to the health and safety of her horses.

Foaling Season at Running Springs

With Annie next in line to foal, anticipation is building at Running Springs. At 324 days pregnant, her udder development and overall demeanor indicate she's getting closer. Although her last foaling was at 345 days, Katie remains vigilant, knowing that mares can vary significantly between pregnancies. Annie's progress is closely monitored with regular pH testing and visual checks to ensure a smooth foaling process.

Running Springs is also home to a diverse group of recip mares, many of whom are experiencing their first breeding season at the farm. Through consistent handling and care, Katie is gradually acclimating them to the process, ensuring they are comfortable and ready to carry future champions.
