Combined Comprehensive Bovine Embryo Transfer
& Artificial Insemination Training Course

Course Info

Our Artificial Insemination Course is only taught in conjunction with our Comprehensive Embryo Transfer Course. We add 1 day before the ET course where the student learns AI, they then continue practicing AI the rest of the week while learning ET. The Combined Comprehensive Bovine Embryo Transfer & Artificial Insemination Training Course is a 6 day school that begins on a Monday and ends at 1:30 P.M. on Saturday.

In the Bovine Artificial Insemination portion of the course students learn estrous synchronization, palpating the cervix, and negotiating the AI gun through the cervix. We also supply an excellent AI Management Manual. The course consists of theory and practical work with young cows. Due to innovative techniques and the use of young cows the average student is usually passing the rod through the cervix in less than half a day.

In the Bovine Embryo Transfer portion of the course students are taught the most economical methods to perform embryo transfer in cattle, thereby maximizing profitability. Students will learn how to select and prepare donors & recipients; and how to collect, recognize, manipulate, classify, freeze, thaw & transfer embryos. 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. This portion of the course is also 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 Artificial Insemination

  1. The primary advantage of artificial insemination is the maximum use of outstanding bulls. Thus, enhancing the genetic value of the herd.
  2. Providing access to high quality bulls at modest prices.
  3. Prevention of transmission of diseases.
  4. Reduces the risk of introducing harmful recessive traits.
  5. Improved general herd management.
  6. Shortening the calving season.
  7. Improved merchandising through the use of well publicized bulls with known reputations.
  8. Enhanced genetic value of your herd
  9. Control venereal diseases
  10. Improved breeding records
  11. Improved safety due to no bulls
  12. Learn estrus synchronization programs
  13. Essential for embryo transfer programs
  14. Sex control by using sexed semen

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. Circumvention of some types of infertility can be accomplished using embryo transfer techniques.
  3. 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.
  4. Prevent disease transmission
  5. Research tool
  6. Embryos are a safe and efficient method of exporting and importing genetic material.
  7. Testing for undesirable recessive traits in the dam.
  8. To obtain bull calves from top cows for young sire programs which identify the best bulls.
  9. Changing from grade cattle to pure-bred animals is less expensive using embryo transfer than buying pure-bred cattle.

Course Syllabus

Each day of the Combined Comprehensive Bovine Embryo Transfer & Artificial Insemination Training 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:

  • Artificial Insemination
  • 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

  • The lab portion in the classroom consists of students practicing on actual cow reproductive tracts and the schools cow model.
  • In the afternoon students will be out at the chutes practicing on school cows learning palpation, passing of the cervix, etc.
  • 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.

"Wesley Larkin does an excellent job of instructing the AI/ET course, both in the classroom and chute-side. He takes the time to ensure that every student, regardless of experience level, is comfortable with the entire process by course completion. This includes flushing donors, transferring to recipients, and performing necessary lab work such as freezing, thawing, and grading embryos. Wesley’s patience and attention to detail make for an enjoyable learning experience, and it has given me the skills and confidence needed to offer ET services to my clients. I highly recommend this course to those interested in expanding their skill set, as it is well-worth the investment."

Bovine Embryos

"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."

Manipulating Embryos

“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.”

Calves Produced from a Heifer via ET

“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.”
