The KJD Process at a Glance
Our streamlined process ensures results beyond all doubt and a seamless experience
Initial Contact & Booking
Contact KJD Veterinary through our website, phone, or email to discuss your needs and schedule a fetal sex determination appointment. We'll collect information about your mare(s) and confirm the optimal timing for the examination.
Scheduling with a KJD-Certified Vet
We'll connect you with a KJD-certified veterinarian in your area. If there isn't one nearby, we can discuss options for video submission or travel arrangements. The appointment will be scheduled during the optimal window (55-250 days of gestation) for accurate determination.
Ultrasound Procedure
The KJD-certified veterinarian will perform the ultrasound examination using our proprietary technique. The procedure is non-invasive and typically takes 15-30 minutes per mare. The veterinarian will record the ultrasound session following our strict protocols to ensure optimal image quality.
Secure Video Upload
The veterinarian will upload the ultrasound video to our secure portal. Our system uses end-to-end encryption to ensure the confidentiality and integrity of your data. If you're submitting your own video, you'll receive secure upload instructions.
Expert Review by Dr. Doyle
Dr. Kevin J. Doyle personally reviews every ultrasound video to determine the fetal sex beyond all doubt. His decades of experience and proprietary technique allow him to identify subtle indicators that others might miss, ensuring unmatched accuracy.
Official Certification
Once Dr. Doyle completes his review, you'll receive an official KJD Veterinary certificate documenting the fetal sex determination. This certificate is backed by our Beyond All Doubt guarantee and can be used for marketing, sales, and insurance purposes.
Optimal Timing
Understanding the critical window for accurate fetal sex determination
The 55-250 Day Window
KJD Veterinary provides Equine FSD services from 55-250 days of gestation. Our proprietary technique enables Beyond All Doubt determination across this entire extended range, offering unprecedented flexibility for breeding programs compared to traditional methods with much narrower windows.

Before 55 Days
The genital tubercle is not sufficiently developed to allow for determination beyond all doubt.
55-250 Days (Available Range)
KJD's advanced technique enables Beyond All Doubt determination across this extended range, providing flexibility for breeding programs
Peak Accuracy Period
While determination is possible throughout the 55-250 day range, certain periods may offer enhanced visibility of anatomical markers.
When you book with KJD Veterinary, we'll help you determine the best examination timing within our 55-250 day service range based on your mare's breeding or ovulation date and your specific needs.

Frequently Asked Questions
What happens if the ultrasound can't be performed during the optimal window?
KJD Veterinary provides Equine FSD services from 55-250 days of gestation. While certain periods within this range may offer enhanced visibility of anatomical markers, Dr. Doyle's proprietary technique enables Beyond All Doubt determination across the entire 55-250 day window. However, to maintain our Beyond All Doubt standard, we may recommend optimal timing based on your specific case and breeding program needs.
How soon will I receive my results?
Dr. Doyle typically completes his review within 24-48 hours of receiving the ultrasound video. You'll receive an email notification when your results are ready, and you can access them through your secure client portal.
What if there isn't a KJD-certified vet in my area?
We have several options for clients without local access to a KJD-certified veterinarian. These include video submission from your regular veterinarian (with guidance from us), travel arrangements for a certified vet to visit your location, or in some cases, Dr. Doyle may be available for high-value breeding operations.
Is the procedure safe for the mare and foal?
Yes, the procedure is completely non-invasive and poses no risk to the mare or developing foal when performed by a qualified veterinarian. It's essentially the same as a routine pregnancy check via ultrasound.
What information do I need to provide when booking?
We'll need basic information about you and your mare(s), including breeding or ovulation dates to calculate the optimal examination window. For registered mares, we'll also request registration information for the official certificate.
