Tool 10.5 Liveweight targets for weaners and young ewes
Liveweight targets for weaners and young ewes
The table below provides a guide for the minimum target liveweights for maiden ewes from birth to pre-joining. The target weight at any given time depends on the standard reference weight (SRW, tool 10.7) of their mother.
Following these guidelines ensures high rates of weaner survival and acceptable reproductive performance in young ewes.

Know and check the growth targets for your weaners
The AWI Weaner management checklist contains key management practices and targets for a thriving weaner mob. The checklist allows you to enter key information, such as SRW, target weights and dates for your operation to customise the information for your flock. You can also track your results against targets to know you're on track.
