Introduction
Synchronization of Recipients with the Donor
- GOAL: To synchronize the donor and recipient to be in the same stage of the oestrous cycle.
- REASON: To prepare the uterus of the recipient to support preattachment embryogenesis.
- HOW: Treat recipient with a hormonal regime that induces oestrus to occur at the same time as the donor.
Superovulation of the Donor
- GOAL: To hyperstimulate ovaries with gonadotrophins.
- REASON: To provide higher than normal numbers of follicles that reach dominance and ovulate.
- HOW: Inject donor with gonadotrophins to hyperstimulate follicular development. Generally FSH or one of its analogs is used.
Inseminating the Donor
GOAL: Inseminate donor with semen from genetically superior bulls. To generate the best fertilization rates and genetic combinations possible. REASON HOW
