Comprehensive Bovine Embryo Transfer Training Course

Course Info

Our 5-day Comprehensive Bovine Embryo Transfer Course begins at 8:00 AM on Tuesday and ends at 1:30 P.M. on Saturday. It teaches the most economical methods to perform embryo transfer in cattle, thereby maximizing profitability. It is designed for dairymen and ranchers wanting to learn how to perform embryo transfer on their herds; as well as veterinarians wanting to learn embryo transfer to incorporate into their practice.

In our Bovine Embryo Transfer Course you will learn how to select and prepare donors & recipients; and how to collect, recognize, manipulate, classify, freeze, thaw & transfer embryos.

The Comprehensive Bovine Embryo Transfer Course Is RACE-Approved for 50 Hours of Continuing Education for Veterinarians and Veterinary Technicians in Jurisdictions Which Recognize the American Association of Veterinary State Boards RACE Approval. RACE-approved Course

Our Embryo Transfer Course Teaches You How to Improve:

  • Reproduction
  • Palpation
  • Estrous Synchronization
  • Genetics
  • Milk Production
  • Animal & Embryo Sales

What You Will Learn:

  • Synchronization & donor/recipient management.
  • How to flush, search, manipulate and classify embryos.
  • Procedure for loading embryos into straws for freezing or transfer.
  • How to freeze, thaw and transfer embryos.
  • Proper completion of embryo transfer paperwork and documentation using International Embryo Technology Society guidelines.
  • We also show you where to purchase all the supplies and equipment that will be needed to successfully perform embryo transfer.

We limit the number of students per school to six. This ensures a high level of teacher/student interaction. Certificates of competency are given to students who complete the course and demonstrate an understanding of the theory & practical techniques of embryo transfer.

Students need to bring clothes adequate for working on cows, we do have boots available if needed. Students are also encouraged to bring a tablet if they have one.

Key Benefits of Embryo Transfer

  1. To produce more calves from a valuable cow. Donors average between 4 to 6 usable embryos per flush (range 0 to 52 in our experience). The average donor can be superovulated successfully about 6 times per year although there is considerable variation between donors. Pregnancy rates should average 65% in beef, and 75% in dairy cattle.
  2. Changing from grade cattle to pure-bred animals is less expensive using embryo transfer than buying pure-bred cattle.
  3. Circumvention of some types of infertility can be accomplished using embryo transfer techniques.
  4. More calves are produced per dose of semen. Two doses of semen are sufficient per superovulation, which will produce an average of 3.5 calves from fertile donors. For instance, 0.5 doses of semen compared to 2 doses of semen per calf under normal breeding practices.
  5. Prevent disease transmission
  6. Research tool
  7. Embryos are a safe and efficient method of exporting and importing genetic material.
  8. Testing for undesirable recessive traits in the dam.
  9. To obtain bull calves from top cows for young sire programs which identify the best bulls.

Course Syllabus

Each day of the Comprehensive Embryo Transfer Course consists of lectures, labs, and chute time. Students are taught embryo recovery (flushing), identification of embryos and eggs, classification, freezing, thawing, and transfer of embryos.

No successful course on embryo transfer can be given without presenting the student with freshly superovulated cows to provide ample opportunities to experience palpating superovulated ovaries. Therefore, we provide freshly superovulated cows, giving the student the opportunity to practice sufficient flushing & palpation. Frozen-thawed eggs and embryos are available for additional practice whenever needed.

We supply all the equipment needed for the school and we only use young, fertile cycling cows which are observed for heat every day to ensure optimal results.

Subjects Taught:

  • Selection of donors & recipients-genetic & physical aspects
  • Reproductive physiology
  • Synchronisation of estrus using prostaglandins, progesterones & GnRH
  • Superovulation-use of follicle stimulating hormones, mechanisms of follicular maturation, ablation & ovulation
  • Heat detection methods
  • Breeding strategies and techniques
  • Methods of embryo & egg recovery
  • Techniques of transferring embryos-palpation of cervix, uterus, ovaries, follicles & corpora lutea
  • Preparation of media
  • Description, preparation & care of stereozoom microscopes
  • Location, manipulation & classifiaction of embryos
  • Sanitation of embryos for domestic use & for export
  • Techniques for cooling embryos for deep frozen storage using ethylene glycol & glycerol
  • Preparation of frozen-thawed embryos for transfer
  • Record keeping


  • The classroom portion consists of lectures and PowerPoint presentations covering all aspects of embryo transfer protocols and techniques.
  • The lab portion in the classroom consists of students practicing flushing on actual cow reproductive tracts, getting accustomed to working with microscopes, handling embryos, freezing embryos, etc.
  • The remaining part of the day students are out at the chutes practicing on school cows. Students will be practicing passing AI guns, ET guns, and catheters for flushing and ultrasound.
  • The lab portion in the classroom consists of students practicing flushing on real cow reproductive tracts, embryo handling, and embryo freezing.
  • The remaining part of the day students are out at the chutes practicing on school cows. Students will be practicing catheter placement and flushing of the uterus.
  • Students flush school cows to collect embryos and then freeze the embryos collected.

Note: All students will be at different levels of experience, there are two chutes for everyone to be able to work on whatever they would like, along with reproductive tracts and models in the classroom. While we have a schedule, the school is focused on giving every student the needed practice they require. Throughout the week students will be able to choose what they would like to focus on and practice during the time at the chutes.

Course Hours

The Comprehensive Embryo Transfer Course is a 5 day school that begins on a Tuesday and ends on Saturday. Class starts at 8:00 A.M. each day and finishes at 6:00 P.M. (except on Saturday when class finishes at 1:30 P.M.).


Competence in AI (artificial insemination) is required. For those students who need training in AI we offer a combined AI & ET training course. The AI training portion is a 1 day school held the day before the embryo transfer school. Then the student continues practicing AI for 5 days while learning the embryo transfer methods.

"I found the embryo transfer course taught by Wesley Larkin to be exactly what I needed and more than I expected. Through veterinary school, I did not get enough actual hands-on learning with advanced reproduction procedures. Being taught by Wesley in a small class setting was an ideal learning environment, I gained the tactical skills and knowledge needed to successfully and confidently flush cattle for myself and future clients. I would recommend the class to anyone ready to take their veterinary practice or cattle program to the next level. Wesley was more than willing to answer any questions I had and even help me after my completion of the course. A quality class taught by a quality instructor - it was well worth my money and my time."

Searching for Embryos

“I was part of Wesley’s first class after he took over for Dr. Elsden. He did a great job of moving slow and making sure we were all on the same page and understood each step. We spent a lot of time looking at embryos either in pictures or through the microscope. He wanted all of us to be confident in what we were looking at when we left the school. When it came to cow work, he allowed us to get in the cows as much as we wanted to ensure we were confident in what we were doing. My first group of embryo calves are currently being born and I could not be happier.”

Bovine Embryos

“Wes was a great instructor. He was very patient and did a great job explaining the process of embryo transfer and what to look for in a good embryo. Wes thoroughly explained the freezing process as well as how to transfer fresh embryos. He made it easy to understand. He gave out handouts and provided pictures to help with AI timing and embryo stage identification. Overall, I would say that this school has provided me the tools and understanding that I needed to grow my herd. I appreciate the time and effort he put into the class.”

“Wes, I wanted to thank you for putting on such a great class back in November. With all your tips and tricks of the trade I learned more than I had expected I would. It has been a great year with some successful flushes and more confirmed pregnancies than we have ever had in the past. By using your methods my conception rate is up more than 20% and I couldn’t be happier with amount of great genetics I will be adding to my herd next year thanks to your complete knowledge and experience in the cattle industry.”
