Embryo Transfer Event (Platform Event, EC 3000)

The VAS PULSE Platform Embryo module is a valuable tool that allows you to manage your Embryo Inventory and enter Embryo Transfer events in the mobile app. The PULSE Platform makes adding embryos simple, and defining embryo details in advance saves you precious time during embryo transfer tasks while out on the dairy with your embryo technician.

You can find this feature under the DairyComp menu.

This topic explains how to use an Embryo Transfer event in the mobile app to record when a recipient female has received a transferred embryo that originated from either an IVF In-Vitro Fertilization. In relation to embryo transfers, IVF occurs when oocytes (eggs) are collected via OPU (ovum pick up), and then in a lab, semen is added to create embryos. or embryo flush Embryos are harvested by being flushed out of a superovulated cow that has already been bred.. For help viewing Embryo Inventory, or adding and editing embryos, see the Embryos topic in the DairyComp section of this online help.

Select an Embryo from Inventory

After embryos are added to Embryo Inventory in the web version of the PULSE Platform, they are available for selection from the mobile app. Complete the steps below to select an embryo from inventory for the Embryo Transfer event (if you need help creating the event, see Tips for Entering Events:

1. Tap the button at the top left of the event page, and choose an animal to add to this event.

   The app allows you to add female animals in OK/Open or Heifer RPRO Reproductive code status, and warns you if you attempt to add animals that do not meet these criteria. The app will not restrict you from adding a female that is dry, already pregnant, younger than the minimum breeding age, recently freshened, or flagged as "do not breed"; it simply warns you of their status so that you can determine whether to continue.

2. Tap the Embryo field to select the embryo. The app opens a new page that shows the available inventory: 

   

3. Tap an embryo to select it. The app auto-populates the Embryo Transfer event details based on the information defined in the Embryo Inventory.
   
What happens when I select an embryo from inventory?

The embryo is reserved for this animal, and it is removed from inventory on your device. Other users will continue to see the embryo until you tap the Process My Changes button. If another user selected the same embryo before you processed the event, a warning that the embryo has already been used displays when they attempt to process the event:



What if I select the wrong embryo?

If you accidentally select the wrong embryo, tap the Embryo field again, select the correct embryo, and tap Yes to confirm:



The previously selected embryo returns to inventory on your device.

If your WiFi or data connection is down, you will see the following message and not be able to access embryos in inventory: 



To continue without a connection, proceed to Add a New Embryo. To verify that embryos exist in inventory, go to the Embryos page in the web version of the PULSE Platform.

4. Define any additional details for the event and process the event. See Define Details for this Event for more information.

Add a New Embryo

Do the following to add a new embryo to the Embryo Transfer event:

1. Tap the button at the top left of the event page, and choose an animal to add to this event.

The app allows you to add female animals in OK/Open or Heifer RPRO status, and warns you if you attempt to add animals that do not meet these criteria. The app will not restrict you from adding a female that is dry, already pregnant, younger than the minimum breeding age, recently freshened, or flagged as "do not breed"; it simply warns you of their status so that you can determine whether to continue.

2. Tap the Embryo field and select .
3. The embryo fields become editable and you can add details for the embryo: 



4. Define any additional details for the event and process the event. See Define Details for this Event for more information.

Define Details for this Event

When you select an embryo from inventory for the Embryo Transfer event, the embryo details will auto-populate and some values become uneditable. Stage and Grade, however, remain available for updates until the event is processed. See the information below for help defining Embryo Transfer event details. All required fields are marked with an * (asterisk) symbol and must be added before you can process the event.

What Happens When I Process Changes for this Event?

When you tap the Process My Changes button in the mobile app, it sends your updates to the PULSE Platform (WiFi or data connection required), which then sends them forward to DairyComp 305.

When the PULSE Platform receives the completed Embryo Transfer event from the mobile app, it makes the following updates:

1. Inserts a TRANSFER event on the recipient female's Platform CowCard. This event is not tracked on-premise in DairyComp; it is specific only to the PULSE Platform CowCard.
2. If an embryo from inventory was used for the transfer, moves the embryo from the Frozen or Fresh tab to the Transferred tab in Embryos.
3. Adds the event details for any new embryos to the Transferred tab in Embryos.

The PULSE Platform then sends the event details it receives from the mobile app to DairyComp 305. When DC305 receives a completed Embryo Transfer event from the PULSE Platform, it processes the following changes:

• Records a BRED event and updates the RPRO status for all completed animals in the Embryo Transfer event. Note the following guidelines for how the PULSE Platform and DC305 record the BRED date based on whether the Embryo Age is defined or not:
  • If the Embryo Age is defined in the Embryo Transfer event, then the BRED event is back‑dated based on the Age entered. For example, if the embryo is 7 days old and today is 8/21/19, then the PULSE Platform TRANSFER event is recorded as 8/21/19, and DC305 will receive a BRED event dated 8/14/19:

    

  • If the Embryo Age is not defined in the Embryo Transfer event, then the date of the transfer is used for the BRED date:

    

• Assigns the embryo an ID, which is auto-created from the data entered in the PULSE Platform TRANSFER event. This ID stays with the embryo for the entire duration of the pregnancy.
• Records the embryo's sire ID as the SIRC Sire of conception.
• Clears the recipient's ETDAM Embryo transfer dam (donor female) value once the embryo is transferred to the recipient female.
• If DC305 receives an embryo transfer event for a pregnant animal, it updates the animal's record to show a status of Vet Code 6 = ABT? Vet Code 6 = ABT? Often if a dairy sees a pregnant animal showing signs of heat they may breed her. When this breeding is entered in DairyComp the animal remains pregnant, but this flag is set so that the veterinarian can determine if she is still pregnant to the original breeding or if she has aborted and is now just another "bred status" cow..
• When DC305 later receives a FRESH event for the recipient female and the ET Embryo Transfer Module is enabled, then the embryo transfer is marked as "successful."

• If you have not selected the Sire and/or Breeding Code for an animal in this event, the app will not include that animal when it sends the batch Embryo Transfer event updates back to DairyComp 305.
• Any incomplete animals will remain visible in the mobile app Embryo Transfer event until you either remove them from the list or finish defining their details and process the changes again.

See also Details Required to Process Animals in an Event for examples of how the mobile app displays complete vs incomplete animals.

See Processing Your Changes for more information on how the mobile app, the PULSE Platform, and DairyComp 305 work together to process your changes.
