A good start at calving is key for optimal performance throughout lactation. With Active Tag continuously monitoring your animals, Datamars Livestock will alert you immediately before, or just after calving.
📝 The 'Calving Alerts' feature works best in indoor operations.
📢 The Calving Alert feature is available on request. Click on the Live Chat bubble in the bottom right-hand corner of this screen or email sf-support@datamars.com.
Monitoring when calving has occurred means:
You will know what is happening in the calving pen, even when you are not there.
You can identify cows which have recently calved.
You can focus on giving cows and calves a good start.
How does Datamars Livestock know when an animal has calved?
Datamars Livestock will trigger a calving alert if an animal exhibits irregular behaviour during her calving window. The calving window is between 250 and 310 days after the pregnancy has started.
💡 The calving alerts feature only works if an insemination date or pregnancy scan data is entered in Datamars Livestock manually or via an integration.
How can I tell when an animal has calved?
Animals which have triggered a calving alert are included in the Calving alerts report.
24 hours after calving, they automatically leave the list. This ensures you always have a real-time view of animals which have recently calved.
You can configure your notifications so that you receive an alert when Datamars Livestock detects an animal has calved.
Once you have confirmed that an animal has calved, we recommend adding a calving event to the animal's record either directly in Datamars Livestock or in your Farm Management software.

How does Datamars Livestock determine the cow's expected calving date?
This date is derived from the last insemination date or the last pregnancy check with 'days in calf' recorded and the gestation length. The default gestation length is 283 days, but this can be configured in the web app (Farm Settings > Reproduction > Edit reproduction configuration > Gestation length.
A cow has calved on my farm but I didn't receive a 'Calving alert' notification - why not?
There are several possible reasons:
The 'calving alert' notification is disabled by default. Check that you have enabled this alert for every Datamars Livestock user on your farm who needs to know this information.
A 'calving alert' notification can only be sent for animals with an expected calving date. See above for details on how Datamars Livestock determines the expected calving date.
An active tag must be fitted for 7 days before a notification will be sent.
It is possible that an animal's behaviour did not change for long enough to be identified by the algorithm. This happens from time-to-time, usually for cows which have calved unassisted.
Why have I received two likely calved notifications for one cow?
If you don't manually record a calving event in Datamars Livestock to confirm the 'Çalving Alert' notification, the system will continue to look for irregular animal behaviour until 10 days after an animal's expected calving date. It is best practice to confirm the calving alert by recording a calving event.
