Frequently Asked Questions

Conventional embryo production relies on natural, in vivo processes, using the donor cow as the culture system. IVF (in vitro fertilization) produces embryos outside the donor in a laboratory setting after oocyte collection.

IVF programs generally offer faster turnaround and more flexible scheduling. Conventional embryo collection requires a longer timeline, typically 17 to 31 days from start to finish.

Conventionally produced embryos typically offer more consistent and higher conception rates, particularly in fresh transfer situations.

Conventional collections average 6–7 viable embryos per donor per collection. IVF embryo numbers can vary more widely and may allow for more frequent collections, depending on donor response.

IVF programs require significantly less semen per embryo, making them an ideal choice when semen supply is limited or when using high-value or rare sires. Conventional programs require a greater quantity of semen.

IVF programs offer more reliable gender control, especially when using sexed semen. Conventional embryo production is less effective for precise gender selection and is often chosen when gender is not the primary objective.

Conventional donors require synchronization and hormonal stimulation and are collected less frequently. IVF donors can often be collected more frequently and may be better suited for donors that do not respond well to conventional stimulation.

Conventional embryo production generally offers a lower cost per embryo, especially when producing embryos at scale. IVF programs may carry a higher cost but provide added flexibility, efficiency, and genetic precision.

The best option depends on your goals, donor population, semen availability, desired timeline, and budget. Cross Country Genetics works closely with clients to evaluate these factors and recommend the program that best aligns with long-term objectives.

IVF procedures can be performed as frequently as every 14 days, allowing for increased flexibility and more frequent embryo production from selected donors.

Yes. Oocyte pickup (OPU) can be safely performed on pregnant donors within the first 100 days of pregnancy.

IVF programs can utilize conventional semen, pre-sorted semen (gender-sorted prior to freezing), or reverse-sorted semen. Reverse sorting involves thawed semen that is gender-sorted at the IVF laboratory immediately prior to fertilization.

The Cross Country Genetics veterinary team works closely with each client to develop a breeding plan aligned with their program goals. Our attention to reproductive detail, personalized herd solutions, and extensive industry experience allow us to help maximize genetic potential and overall herd productivity.

Conventional embryo collection is the foundation of the embryo transfer (ET) industry. It relies on natural, in vivo reproductive processes, using the donor cow as the culture system for embryo development.

Conventionally produced embryos typically deliver consistent results, strong conception rates, and a lower cost per embryo. This option is often selected by clients looking to efficiently produce embryos across a larger donor population.

The process generally takes 17 to 31 days from start to finish, depending on donor response and scheduling.

Average collections result in 6–7 viable embryos per donor per event, though results can vary based on individual donor factors.

Yes. Conventional collections require a greater quantity of semen compared to IVF, which can be a consideration when using limited or high-value sires.

While sexed semen can be used, conventional embryo collection is generally less effective for precise gender control. Clients often choose this method when their goal is volume rather than gender specificity.

We have observed improved post-collection breeding success when donors are synchronized using the 7&7 protocol, particularly when initiated at or shortly after collection. Even with these improvements, donors most often calve later in the year following collection.

CCG veterinarians are equipped to transfer both fresh and frozen embryos produced through conventional and IVF methods

Fresh conventional embryos are maintained at room temperature and transferred within 1–5 hours of collection. Fresh IVF embryos are held in incubators at elevated temperatures from post-culture assessment until transfer. Frozen embryos are stored at our clinics and thawed and transferred at a time that best fits recipient readiness.

Frozen embryos offer flexibility in scheduling and recipient management. They allow transfers to be planned around recipient availability rather than collection timing.

Yes. We work closely with clients to plan and optimize transfer day, dedicating time and resources to ensure recipient readiness, timing, and overall program success.

Frozen embryos can be transported from our clinics to your farm for thawing and transfer. Fresh transfers may also be coordinated depending on logistics and program needs.

Our goal is to manage your program from conception to calving. That means supporting not only embryo production, but also transfer planning and execution to maximize success for both your operation and ours.

Donor cows and heifers are the foundation of embryo production. Proper donor selection, scheduling, and management are critical to achieving consistent and successful embryo yields.

Cross Country Genetics works closely with each operation to assist with donor selection, scheduling, stimulation protocols, and long-term genetic goals. Each donor is evaluated individually based on breed, age, reproductive status, body condition, and prior reproductive history.

While donors are often discussed as groups, each donor is a unique individual and requires personalized evaluation, timing, and follow-up to maximize success.

Yes. Donor housing is available at all Cross Country Genetics clinic locations.

In-clinic housing allows veterinarians and donor managers to closely monitor reproductive cycles and donor performance. This hands-on approach supports more precise management, reduces the risk of stimulation failure, and enables advanced management strategies that may not be feasible on-farm.

The success of an embryo transfer ultimately depends on the recipient female. Even high-quality embryos require the right recipient to carry them to term and produce a viable, marketable calf.

Recipient selection is based on careful evaluation of age, postpartum interval, breed, body condition, overall health, nutrition, and synchronization strategy.

Yes. We work with clients year-round to understand their cow herd and recipient program, allowing for proactive planning and improved outcomes on transfer day.

Clients may contact any Cross Country Genetics clinic location to inquire about recipient housing.

In-clinic recipient programs allow our team to manage nutrition, synchronization, and transfer protocols on-site. This approach is designed to maximize the use of fresh embryos and optimize transfer timing for the best possible results.

Cross Country Genetics utilizes ultrasound pregnancy diagnosis to confirm pregnancy, determine fetal age, and identify fetal gender.

When pregnancy diagnosis is performed prior to 110 days of gestation, it allows producers to evaluate the success of an embryo transfer (ET) or artificial insemination (AI) program early enough to make informed management adjustments.

Yes. Early evaluation provides valuable insight into program performance and creates an opportunity to refine management and breeding strategies for the following season.
