June: A checkpoint in the season 

While heat detection, AI timing, and semen handling are often questioned first, nutrition is frequently a contributing factor, particularly during the transition from peak to mid-lactation, writes Laura O'Connell.

Where cows are 30 days or more since service, early scanning can provide valuable clarity and allow time to act if problems are identified, writes Laura O'Connell.

For most spring-calving dairy herds, June represents a natural checkpoint in the season. Cows are now post-peak milk production and typically four or more weeks into the breeding period. 

The intensity of calving and early lactation has passed, and attention is turning to how well cows are holding to service.
