Improve the nutrition of your sheep. This means either improved grazing management or strategic feeding of supplements. For more information see 'Nutrition to enhance resistance and resilience to worms'.

Improve your grazing management - This will improve the nutrition of your sheep. It can also help to limit the number of worm larvae eaten by sheep. For more information see 'Pasture management'.

Include immunity to worms in your breeding program. For more information see 'Genetics-breeding worm resistant sheep'.

Limit your use of drenches - Drench strategically at critical times to prevent the development of overwhelming worm infections.  Regular worm egg count monitoring tells you when the sheep need a drench and is much better than guessing.

A professional adviser can help you to integrate these strategies into your management program.
