We work closely with several embryo calf contract rearers. This involves our clients providing embryos, which we transfer into contract recipients. The embryo calf is raised to 7 months of age, at which time the owner of the embryo takes delivery of the calf.
Additionally, we can provide recipients which can have embryos implanted into them and sold. Once a pregnancy has been established at 90 days, the client then takes delivery and ownership of the pregnant recipient.
