The use of a synchronisation programme may be a good option for dairy farmers this breeding season.

A programme can be used on the heifers and select cows, with them often being used on animals being served sexed semen.

Synchronisation programmes have developed due to a number of reasons, such as heifers on many farms being on out-blocks and the increased use of sexed semen.

There are a number of different programmes based on products used, but what is important is that you follow the steps outlined by your vet.

Synchronisation programme

Ensuring that heifers are suitable for synchronisation is important before a programme takes place on farms.

Heifers need to be on target or ahead of target weight in order to increase their chances of holding to service on the programme.

A synchronisation programme can also be used on cows and is often used on cows that are later calving.

The use of a programme can push them forward in the calving pattern and have them calving earlier in the season.

The programme used for cows is generally different from the one used on the heifers, so it is important that you are communicating your plans with your vet.


When it comes to a synchronisation programme, timing is very important and a discussion should take place between your vet and artificial insemination (AI) technician.

Discuss the programme with your vet and ask them to write it down, so that it can be easily followed.

Your AI technician needs to be communicated with as to when you are planning on completing the programme.

This will give them time to plan and ensure that they are available when you are planning to serve the heifers or cows.

Depending on the number of animals, more than one technician may be needed.
