Abstract

• Lucerne is a valuable forage for finishing lambs in late spring and summer, but growth rates of lambs grazing lucerne may be lower than expected, and higher growth rates can be achieved on other forages despite similar apparent nutritive values
• Lucerne is a natrophobe as it has low forage sodium levels
• A recent survey in south-eastern Australia demonstrated most dryland lucerne samples had sodium concentrations below livestock requirements
• Supplementation with salt may increase lamb liveweight gain when grazing lucerne
• Supplementation with barley grain does not appear to increase liveweight gain in lambs but may result in substitution of barley for lucerne.
