For the next few weeks, producers will have a few parasite issues on their mind. Fairly widespread rain has been largely welcome and worm/fly activity will depend on what happens next. More rain and mild conditions will increase fly and worm activity. No more rain and hot conditions will probably mean little change.
There are a few simple principles to keep in mind:
1. Don't guess about the level of worm activity—monitor it with Worm Egg Counts (WECs)
2. Test drench effectiveness—drenches to which worms are resistant look effective (the animals appear to respond), but relief is short lived and reappears rapidly and more severely.
3. Use proven tools to help—Drench Decision Guides, and seek professional advice if you are at all uncertain or have resistance issues.
