Aims

The project aims to assess the benefits of using alternative grass forage species and newer Clearfield technologies to provide
high quality fodder that will finish lambs in a grass-seed free environment.

Key messages

Sowing feed into dwindling lucerne stands; either barley or the newer forage ryecorn varieties resulted in increased weight gains of lambs when compared with those lucerne stands where annual grasses were becoming more dominant allowing lambs to be finished quicker prior to the onset of grass seeds
• Oversowing with Scope CL provides a flexible option in the grazing system with the ability to graze for feed in a seed free environment, or to lock up for grain if seasonal conditions are favourable 
• Heavy stocking rates (and possibly small paddocks or strip grazing methods) are needed to keep newer
forage ryecorn varieties grazed down to maintain feed quality and maximise grazing benefits.
