Embryo Program

Experience Canadian Genetics 

One of the key values for Jersey Canada is to foster growth for the Jersey breed by providing tools and resources to meet the demands of a changing dairy industry. Embryo transfer (ET) is used in cattle to amplify reproductive rates of valuable females. Ideally, it helps reach both genetic and financial objectives. 

Semex, a world leader in A.I technology and Jersey genetics, promotes and exports Jersey embryos through its international distribution network. Whether you are interested in superior production, deep pedigreed cows, specific bull mothers, solid Canadian cow families or stellar show animals, Semex’s embryo program can provide opportunities to strengthen your herd and compliment your goals. 

If you are a Canadian breeder looking to market high quality embryos, the Canadian Jersey Embryo Program can help. Semex maintains an extensive list of embryos available for sale from Canadian breeders, and this list is shared with their worldwide distribution network. If you have embryos available from previous flushes or you have upcoming flushes and would like to be added to the list, contact Melissa or Jean Marc with the following information:

- Donor dam name and registration number
- Donor dams must have a DNA microsatellite or SNP genomic test completed. If embryos are for export, a DNA microsatellite test is mandatory. If embryos are for on-farm use or domestic sales, either a DNA microsatellite or SNP genomic test is acceptable.
- Donor dam photo (if available)
- Sire of embryos
- Quantity of embryos available
- Comments relating to donor dam’s family
- Asking price for embryos

Jersey breeders selling embryos through the Canadian Jersey Embryo Program will receive payment following the sale and delivery of their embryos. Sellers will be invoiced directly by their ET veterinarian for health certificates and transport fees associated with shipping embryos to Semex.

Whether you are a seller or a buyer, we have a few tips on the topic of embryo transfer

Donor Selection
Donors can be animals from superior cow families, tremendous producers, show animals, genomically superior animals or a combination of all these. Jersey Canada recommends genomic testing of all donors to help in making better mating’s for a flush. A DNA certificate must be filed with Jersey Canada for every donor dam; either a microsatellite or SNP genomic test is acceptable. Jersey Canada recommends pulling tail hairs from the donor dam the day she is flushed. 

Selection of Sires 
Since half of the genes come from the male, it is extremely important to use genetically superior bulls.

Selection of Recipients
Sometimes, using the farmer's own recipients simply is not feasible because of insufficient suitable animals and management capabilities. The specific details of facilities, health tests, types of animals used, nutrition, and so on, vary from farm to farm and from country to country. Cows and heifers as recipients both have disadvantages and advantages, and the choice depends on careful analysis of various factors. Excess embryos are frozen when insufficient recipients are available; conversely, when excess recipients are available, frozen embryos can be thawed and transferred. 

Registering ET Calves
Jersey Canada requires a copy of the full flush report before any calves from a particular flush can be registered. Specifically, Jersey Canada requires the report that lists all of the embryos recovered in the flush (as opposed to individual embryo certificates). When registering an ET calf, be sure to indicate either the recipient’s ID (in the case of a fresh implant) or the frozen embryo ID. Jersey Canada requires that every ET calf be matched to a specific embryo. 

If you have any questions about registering your ET calves, contact Ruth McAlister, our registrar at the Jersey Canada office.
