FAQ
- Roundworm control is a year-round issue with the main effects being in growing animals in their first grazing season
- Disease in sheep is caused by a number of roundworm species
- Anthelmintics (wormers) have traditionally been the main control options for many flocks, but this has led to the development of resistance to these products, which means we need to reduce our reliance on them
- Using wormers correctly along the lines of ‘using as much as is needed and as little as possible’ is now a critical part of worm control
- In this factsheet we discuss how weight and performance data can be used to optimise wormer use in lambs
