Frequently Asked Questions (FAQs)

 

  • What are SimVitro® HerdFlex™ embryos?
    SimVitro® HerdFlex™ beef embryos are IVF embryos commercially produced by the J.R. Simplot Company. The embryos are created using Simplot’s Genetic Recover Oocytes (GROs) from beef herds in the USA to match your specific needs.
  • What are Simplot® Generic Recover Oocytes (GROs)?
    Simplot GROs are the specific oocytes used to create SimVitro® HerdFlex™ beef embryos. Simplot GROs are sourced based on your goals and needs. The GROs are mated to a proven sire to maximize the resulting embryo’s genetic potential.
  • How are SimVitro® HerdFlex™ beef embryos different from standard beef x dairy breeding?
    The beef x dairy cross calf market continues to see declining premiums. A full-breed beef calf can see greater premiums.
  • How do I order HerdFlex™ beef embryos for my operation?
    SimVitro® HerdFlex™ beef embryos are available for order through a network of distributors. Locate your local distributor using our distribution map and contact a representative today.
  • Will HerdFlex™ beef embryos increase the profitability of my calves?
    Depending on market price for day-old calves, HerdFlex™ beef embryos can earn up to 30x more than a day-old Jersey and 6.7x more than a day-old Holstein calf.
  • Do SimVitro® HerdFlex™ beef embryos negatively affect calving ease?
    No, SimVitro® HerdFlex™ beef embryo sires are specifically chosen with calving ease in mind and should not negatively affect calving.
  • What is the generic level of calves from SimVitro® HerdFlex™ beef embryos?
    SimVitro® HerdFlex™ beef embryos can be customized to meet your unique and specific genetic needs.
  • What pregnancy rates can I expect with SimVitro® HerdFlex™ beef embryos?
    You can expect to achieve pregnancy rates similar to the rates achieved by Artificial Insemination (AI). Heat stressed and repeat breeders can even expect an improvement in pregnancy rate over AI because the implanted embryo circumvents fertility-related challenges and starts with the placement of an already viable embryo. Pregnancy rates do however vary greatly because of factors like environment, animal management, recipient quality and season.
  • Why are SimVitro® HerdFlex™ beef embryos recommended as a solution to seasonal challenges in reproduction?
    SimVitro® HerdFlex™ beef embryos can improve the pregnancy rate in a herd by overcoming heat stress. Previous industry research using commercial IVF embryos showed a 10 percent increase in one-cycle pregnancy rate vs. AI in the same herds. Heat stressed animals show an improvement because the implanted embryo circumvents fertility-related challenges and starts with the placement of an already viable embryo.
  • What can Simplot’s expertise do for me?
    The Simplot Company’s deep knowledge of the IVF technology and commercial agriculture allows it to leverage multiple market approaches to help producers achieve their goals. Simplot has a deep, pioneering history in plant and food agriculture, which has fueled research for new ways to develop and feed animals in sustained ecosystems. A strong understanding of commercial-scale food resource development and production has provided the spirit to take advanced reproductive technologies – such as IVF – to a scale beyond breeding stock production and allows commercial dairy producers and cattlemen alike to apply the technology to their businesses.
