High priority is being given to tightening the block-calving pattern at Great Britain-based Picton Castle, to optimize the number of days cows spend on grass, as of May 27, 2003. Only 32% of Picton Castle cows were calving in the first six weeks of the block, when the target should be 75%. Ideally, 75% of heifers should also calve within the first three weeks of calving to give them sufficient time to settle, but the figure at the farm was 50%. Cows scheduled to calve more than 21 weeks after the start of the calving season should be sold. And producers should consider using crossbred bulls to improve herd fertility.
