ET

Embryo Transfer (ET) is an advanced reproductive technology and a progressive tool that can help you produce more offspring from an elite cow and can extend the impact of outstanding cattle genetics.

Summary

Summary

Embryo transfer (ET) is widely used in the beef industry today to mass replicate specific genetics. There is no faster way to generate large numbers of progeny from a particular mating than through one of the embryo transfer programs. No matter if it is conventional ET or if you are using Invitro Fertilization (IVF) you can mass produce progeny in a shorter period of time that all come from the exact same genetics. The ET program has allowed breeders the opportunity to produce more highly sought after genetics and high performing progeny that the market demands.

ET Registration Rules

All donor dams must have a DNA sample on file with BBU through a BBU approved genomic services vendor.
1. Effective August 1, 2016 all donor dams must have a minimum 50K HD genotype on file with BBU. All donor dams must be parent verified using DNA SNPs before progeny can be registered. BBU will recognize older STR and Blood Typing parentage methods on a case by case basis. Donor dams with E.T. progeny registered in the BBU system before August 1, 2016 will be exempted from the 50K HD genotyping requirement.
2. Progeny that are the result of traditional E.T. are not required to be parentage verified.
3. Progeny that are the result of IVF must have IVF aspiration and transfer records from the producing lab, provided to BBU. IVF progeny must be DNA parent verified before registration.
4. When the ownership of a donor dam changes after embryos have been recovered, the owner of the dam at the time the embryos were recovered shall retain the ownership and certification rights of said embryos.
5. Immediately upon the sale (or change of ownership) of an embryo (frozen or fresh), seller must submit to BBU a properly completed BBU Embryo Bill of Sale Form.
6. Immediately upon the sale (or change of ownership) of a pregnant recipient cow, seller must complete and sign the applicable Recipient Transfer Form. This completed form must then be submitted to BBU for recording of the Recipient Transfer. Only the owner of the Recipient cow at the time of birth shall be eligible to certify said calf.
7. Rules and Regulations of the BBU Artificial Insemination Program will apply to all sires used in the Embryo Transfer Program.
