Davis-Rairdan has developed a close relationship with a network of E.T. companies around the world who perform quality E.T. work. Dr. Davis has been involved with the training of veterinarians in the field of E.T. from Australia, New Zealand, Mexico, Colombia and China. This combination of networking and technology transfer as been instrumental to the success and longevity of Davis-Rairdan's international clientele.

Davis-Rairdan International was founded by Dr. Roger L. Davis and Dr. D. Scott Rairdan. Dr. Davis grew up in Saskatchewan raising registered Angus and later Polled Hereford beef cattle. Dr. Rairdan was raised in Alberta on a large grain farm where they also raised purebred Charolais. The professional careers of Dr. Davis & Dr. Rairdan began immediately upon their university graduation, with the 1980 incorporation of Davis-Rairdan Veterinary Services Ltd. Their practice at that time was limited to large animal veterinary medicine and embryo transplants.

The company evolved into an embryo transplant and reproduction specialty practice, thus named Davis-Rairdan Embryo Transplants Ltd. Due to the untimely death of Dr. Rairdan in June of 1995, Dr. Davis was the sole principal until selling the company to Dr. Adam Schierman in 2017.  Dr Schierman is continuing to direct the expansion and operations of the company.

The Embryo Transfer Team

The owner and many of the staff at Davis-Rairdan have had a lifelong involvement within the seedstock cattle industry. We are very much aware of the time, energy and resources that are invested in expanding your genetic base, and moreover, we care that you receive the absolute most for your investment.

At Davis-Rairdan, we are involved in a joint marketing arrangement with our clients. This means we are able to make accessible genetics that would otherwise never be made available. Some of the most elite donor females from North America's finest seedstock producers are offered, many on a one-time only basis. These are highly proven females, many mothers of breed leaders. Most donors have been used in our client's ET programs to improve the genetics of their herd.

To these elite donors, we mate the breed's finest sires, keeping in mind our objective of the essentials; calving ease, maternal power, and of course performance to balance the E.P.D.'s. As we breed the best to the best, this may be the opportunity to improve the genetics of your herd.

At Davis-Rairdan we look forward to the opportunity of working with you to help supply genetics of the specific criteria you require.
