Ewe nutrition is crucial to successful lambing. Knowing what and when to feed ewes is fundamental to ewe and lamb health and survival.
Providing adequate nutrition to ewes during pregnancy and lactation is crucial for reproductive performance.
The nutritional requirements of pregnant ewes are greater than dry ewes from early pregnancy and increase through to late pregnancy and lactation. Twin-bearing ewes have significantly higher nutritional demands than single-bearing ewes and require differential management for improved lamb survival.
Pregnancy scanning for litter size is a necessary and profitable tool for the differential nutritional management of pregnant ewes. Identifying the pregnancy status of ewes also facilitates the identification of passenger ewes, optimised paddock allocation and mob size at lambing, and the selection of replacement ewes based on birth type and rear type.

Current and recent projects
Recent AWI and MLA-funded research demonstrated that pregnancy scanning for litter size was profitable in all agricultural regions and flock types. The average increase in farm profit from scanning for litter size was $5.75/ewe scanned. Capturing the potential profit from pregnancy scanning requires implementing best practice management including selling passenger ewes and differentially managing single- and twin-bearing ewes.
