Frozen embryos grant the flexibility to build customized transfer programs that support the goals of your operation. The freezing process allows embryos to remain viable for many years, allowing the time for smart genetic decisions to be made.

In order to keep their calving window tight, some beef producers will OPU their donors several times throughout the year to create a large inventory of frozen embryos, preparing for one or two large transfer days. In a dairy setting, calves are needed year round. In order to maximize the number of pregnancies, some operations utilize natural heats for embryo transfer, which may only require a few frozen embryos at a time.

That’s the beauty of the frozen embryo- it’s always ready whenever you need it, regardless of your goals.

Tips for Success

• Follow the Direct Thaw SOP provided by Vytelle during implantation
• Utilize AETA certified transfer technician
• Use recipient synchronization protocol designs for 7 to 8 day heats
• Ensure proper handling by embryo inventory
• Investigate export regulations prior to the OPU

Utilizing fresh embryos can increase your pregnancy rate. Some beef producers synchronize a large group of recipients and OPU several donors, enabling all quality embryos to be transferred fresh. To improve performance of lower quality embryos, some dairy producers prefer to transfer grade 2 embryos fresh while freezing the grade 1s for later use. That’s the power of fresh embryos- you can maximize results while creating genetic progress, faster.

For fresh embryo transfers, the time frames for the OPU and the recipient synchronization protocol overlap. Heat detection begins on the day of the follicle aspiration and is a vital piece to success. Monitoring and recording good visual heats aid in better conception rates.

Tips for Success

• Monitor and record visual heats
• Create an embryo priority list
• Always have frozen embryos in the tank
• Use recipient synchronization protocol designed for 7 to 8 day heats
• Utilize AETA certified transfer technician
