Embryo/AI Services

At Reproduction Enterprises we provide embryo services for a wide range of species, including cattle, goats, sheep, and horses.

Embryo Recovery and Transfer Services

We offer embryo services for cattle and small ruminants. These services can be performed at our facility or on-farm. The donors that stay at our facility are tested yearly for major reproductive diseases and are vaccinated on arrival. Pasture is available for donors who are between stimulation schedules. The embryos produced here are frozen or may be transferred fresh depending on the availability of recipients. REI often has recipients available for purchase but we reserve them on a first come basis.

In–Clinic Artificial Insemination Services

We can customize our AI services to match your experience and need. We are available to do as little as AI her, based on your heat detection and phone call, or we offer complete packages that include everything and you simply drop her off and pick her back up.

While they are housed at our facility, we do our best to group animals of similar size and disposition. Precautions are taken to promote safe and comfortable conditions conducive to normal reproductive performance. In the event that your animal becomes sick or injured, our veterinarian will examine her and contact you with a report and recommendations.

On-Farm Artificial Insemination Services

We offer many of the industry accepted timed AI protocols in order to meet your needs. Depending on your location and the number of head, we may arrange to AI from observed heats. Please contact our office for more information and scheduling.

Ultrasound Services

We offer ultrasound services including pregnancy determining and aging to 100 days. Fetal sexing in cattle is available and best performed between 60 and 90 days after breeding. Beyond 100 days, palpation is available for pregnancy determination and an estimation of fetal age.


Our recipient herd consists of primarily Angus cross cattle on pasture. The cows are selected to be able to carry and deliver the calf and to minimize udder problems. They have been tested for Bangs, BVD, and Johnes. Parasite control and vaccinations are maintained regularly. Bovine recipients come with a 150-day pregnancy guarantee with an option to purchase another 75 days.

In Vitro Fertilization/Oocyte Aspiration

We now offer in-house IVF Services. We will house and complete the needed synchronization/stimulation procedures for your donors and then arrange for their oocyte retrieval appointment.
