Summer drenching is the key to minimising worm carryover into next year, by making sure that there are few worms in your sheep getting a free ride into autumn.
A wetter spring means pasture may remain greener for longer. More frequent worm egg count (WEC) monitoring is recommended to ensure a low worm burden in your sheep flock is maintained.
Making a decision about a second summer drench
- monitor worm levels using worm egg counts
- consider the age and class of sheep, their body condition and future grazing choices
- use a professional consultant to establish a decision tree to decide whether a drench is needed, and which sheep can be left un-drenched.
