Pa O'Hanlon & Claire McAuliffe on Pre-Breeding Management

Teagasc Kerry Dairy Ireland Joint Programme Demonstration Farm Advisor, Claire McAuliffe, and Programme Demonstration Farmer, Pa O’Hanlon, join Stuart Childs on this week’s Dairy Edge to discuss pre breeding management to drive submission rate and ultimately 6 week calving rate for the next calving season.

 

Pa first explains how calving has gone on the farm in 2025 and how he has delayed his calving start date over the last few years in order to better align with grass growth on his farm. 

 

In the past no matter how much quality silage he tried to have available, Pa found that he ended up feeding poorer silage to milking cows which was hitting his milk solids production so he has moved the calving date to try to calve closer to grass. This means that he has to achieve the 90% 6 week calving figure to get the best return from the herd.

 

Consequently, Pa is ‘afraid’ not to make the effort in terms of pre-breeding management as he can’t afford to let calving slip. He went on to explain how he has a chart which is very visual for keeping track of cows coming in heat post calving and uses the same chart for tracking AI in the 1st 3 weeks. 

 

This chart helps him to drive his 3 week submission rate and then identify any cows that haven’t been served as soon as the 3 weeks are past. He find this visual trigger much better than info on his phone as he would have used in the past.

 

Claire then highlights the performance of the demonstration farmer group and gave examples of some of the effort they are putting into pre-breeding management to drive the submission rate once AI commences. 

 

She also pointed out that many of the farms had opened with lower covers than they should have and found that they weren’t able to exploit the excellent grazing conditions this spring as much as they would have liked to. 

 

The recent uplift in growth has helped their cause and their action has ensured they now have adequate grass moving into the 2nd rotation. 

 

This needs to be a key focus for all of the farms at the end of this year to ensure they hit the closing cover targets so that there is adequate grass on farms in the spring of 2026. 

 

This is a major weakness at commercial farm level as pointed out by Michael O’Donovan on a recent episode.
