Donor Sire Selection

Today frozen semen is available from a large number of sires. Choose a sire that meets your genetic and phenotypic criteria. High quality semen is a must. If there is any question about the semen quality have it tested preferably at a bull stud by qualified personnel.

To ensure that the embryos are exportable to most countries of the world, the semen must meet Canadian standards for export to USA or have been legally imported into Canada. Owner's Use Only and Canada Use Only semen will limit export opportunities if this is a concern. Natural service works well providing the bull to be used has been tested and has high quality semen. The ultimate when using fresh semen is to collect it and inseminate raw fresh semen. This is also an excellent treatment for donors who consistently give large numbers of unfertilized ova for no reason.
