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. The AI Course is a 1 day class taught the Monday before the 4.5 day ET Course.

In the Artificial Insemination portion of the course you 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. Further ample AI practice occurs the next 4.5 days while learning the ET techniques.

The Bovine Embryo Transfer portion of the course 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. Veterinarians can also apply to their state veterinary associations for up to 50 hours of Continuing Education Credit for attending this course. (based on 12 hours of lecture and 38 hours laboratory techniques).

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.

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 IETS guidelines.
  • We also show you where to purchase all the supplies and equipment that will be needed to successfully perform embryo transfer.

Day 1 of the Comprehensive Bovine Embryo Transfer Training Course is mainly classroom lectures and labs. In the lab portions students are first taught how to pass and set the catheter using our artificial cow. Students then practice passing the catheter and placement of embryos on real cow tracts. Starting on day 2 of the ET portion of the course, students move out to the cattle chutes to practice on superovulated cows with the opportunity of unlimited flushing & palpation each day for the remainder of the course.

Unlimited frozen-thawed eggs and embryos are available for additional practice whenever needed. We supply all of the equipment needed for the school and we only use young, fertile cycling cows which are observed for heat to ensure optimal results.

We limit the number of students per school to six. This ensures a high level of teacher/student interaction. Certificates of competency are given after completing the 4.5 day class & and the student demonstrates an understanding of the theory & practical techniques of embryo transfer. Over our many years of teaching this course we have found it takes the average student 4.5 consecutive days to absorb all the instructions & to adequately experience the different manipulations in cows & at the microscope.

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

The combined ET and AI course is a 5.5 day school that begins on a Monday and ends at noon on Saturday.

The 1 day AI class consists of 2 hours theory and 6 hours practical experience.

Subjects taught in the 1 day AI course are:

  • Description of bovine reproductive tract
  • Description of bovine reproductive cycle
  • Methods of estrous synchronization
  • Descriptive demonstration on how to pass a rod through a cow's cervix
  • Methods of thawing frozen straws
  • Care of liquid nitrogen tanks
  • List of equipment needed for AI

The second day begins the comprehensive bovine embryo transfer course. Our Comprehensive Embryo Transfer Course consists of 4.5 days of classes. Each day consists of: 2 hours of lectures in the morning, followed by practical work (consisting of flushing superovulated donors and learning laboratory techniques for managing embryos) for the remainder of the day; so approximately 80% of the students time is spent performing practical work. There is no set finishing time on any day, it is up to the student to finish when they are satisfied the technique is mastered. On the last day, placement of the embryo transfer gun for transferring embryos is practiced with a new set of cows. Students are again asked if they want anything repeated.

Subject taught in the ET course are:

  • 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

Course Hours

The course begins on a Monday and ends at noon on Saturday. Classes start at 8:00 A.M. each day and finish betwen 5:00-6:00 P.M. (depending on the number of embryos collected and student application). Class finishes at noon on Saturday.


Their are no academic prerequisites. Competence in AI techniques is an advantage but not a necessity. All one needs is the enthusiasm to learn a new technology.
