Selecting replacements: Many mid-season flocks lambing in early to mid-March are now approaching or in the midst of weaning lambs. Farmers retaining replacements from within the flock should identify potential replacements early in the season to avoid the best-performing genetics leaving the flock in the first few drafts. It is advisable to select a higher number of replacements than will be eventually required as this will allow performance to be monitored post-weaning and provide an opportunity for further selection down the line.

Reports indicate that many of these flocks are also pulling their first drafts of lambs before they wean and this is keeping a floor under throughput. There is an opportunity to select lambs at a lower liveweight pre-weaning due to a higher kill-out potential. Grass-finished lambs should kill out in the region of 47% to 48% on average but this can vary significantly.
