Embryo Transfer in Quarter Horses – Advanced Reproduction for Elite Genetics
Embryo transfer (ET) has revolutionized Quarter Horse breeding in the U.S., allowing elite mares to produce multiple foals per year.
This technique separates genetic contribution from gestation, giving breeders a powerful tool to replicate high-performance bloodlines without compromising the mare’s competition or health.
1. How Does Embryo Transfer Work?
The process involves:
- Inseminating a donor mare
- Flushing the embryo 7–9 days post-ovulation
- Transferring it to a healthy recipient mare with a synchronized cycle
2. Ideal Candidates for ET
Embryo transfer is commonly used for:
- High-performance mares still in competition
- Mares with previous foaling issues
- Mares with exceptional genetics
3. Managing Donor and Recipient Mares
Both mares require:
- Precise hormone management
- Daily monitoring during the cycle
- Follow-up pregnancy confirmation
4. Cost vs. Return on Investment
Though ET can cost $3,500–$7,000+ per attempt, the ability to multiply offspring from one mare makes it a valuable strategy for breeders aiming for elite markets.
