Determine pregnancy and litter size in ewes, to facilitate nutrition planning.


Ewes can be scanned to diagnose pregnancy and expected litter size. This facilitates nutrition planning pre-lambing. Expected lambing date can also be predicted.

How to implement:

A trained operator uses an ultrasound scanner and specially designed crate to quickly identify pregnancy and/or expected litter size. Ewes are marked to record litter size and EID recording may be used.

Expected benefits:

  • Quick, stress free and undertaken with sheep in standing position in a designated crate.
  • Identifies barren ewes that can be culled or sold.
  • To facilitate nutrition planning in late pregnancy ewes can be grouped according to expected litter size to avoid under or over feeding.

Prerequisites and/or limits:

  • Ewes should be restricted from feed for about 10 hours in advance of scanning
  • Availability of trained operator with equipment
  • Facilities to group ewes according to expected litter size pre-lambing
