Described by dairy experts as individual-cow maternity monitoring device, calving detector was developed by a French manufacturer Medria and it has been tested in most parts of the world.

This system uses thermometer equipped boluses inserted intervaginally in cows, typically a week after their anticipated due date.

“With this set and connected with mobile phones, a farmer will receive a text message on activated bolus and the time and date it was inserted,” said Justine Kinaro, vet nary expert.
