- Advanced Breeding
- Choosing between MOET and IVF
- In order to perform MOET on a cow, she will need to be superovulated, which involves a series of twice daily injections. Superovulation causes the cow to release more eggs than normal when she comes bulling, resulting in multiple embryos.
- Some cows fail to respond to superovulation – in these cows IVF is recommended
- Embryo transfer can be performed on a cow once every 2 months, whilst IVF can be performed every two weeks
- After a few rounds of collections, it is advised to let animals breed naturally and calve, in order to let the ovaries rest and recover
- Both MOET and IVF can be performed on maiden heifers and adult cows
- The number of embryos recovered by either technique varies widely between individual animals
- The need for correct nutrition and management of both donors and recipients is vital for the success of both methods
- MOET is, at the moment, cheaper than IVF
