Cows breeding in field

According to Teagasc, the goal is to get 90% of cows served in the first 3 weeks of the breeding season. Recording heat detection for a full month before the start of the breeding season gives every cow the chance to come into heat at least once before they are due to be bulled.

You can then quickly check what cows have not come into heat or have had no heat observed and take action based on that.

Cows that have not cycled since calving can be treated before the breeding season starts, which should help you hit the 90% mark in the first 3 weeks.
