Emma the Farm Vet: Worming Cattle at Housing: Why Does Timing Matter?

October 30, 2026

Veterinarian Expert

When should you worm cattle before winter housing?

Emma the Farm Vet explains why cattle parasite control starts with understanding the risk, identifying the parasites involved and considering whether - and when - treatment is needed.

In this episode of Farm Vet Fridays, we explore pre-housing worming, gut worms and lungworm in cattle, and responsible treatment planning for beef and dairy herds.

Emma also discusses doramectin, an active ingredient in certain veterinary medicines used to treat parasites including gut worms and lungworm.

‍

Watch to learn more about:

✓ Understanding which parasites you’re targeting

✓ Considering treatment timing around housing

✓ Following COWS guidelines and responsible-use principles

✓ Using appropriate diagnostic tests to support decisions

✓ Supporting cattle health and welfare

✓ Helping preserve the effectiveness of antiparasitic medicines

‍

Don’t base your housing treatment on the calendar alone.

Your cattle’s grazing history, parasite risk, previous treatments and diagnostic results should help guide your plan, alongside advice from your vet or SQP.

Know the risk. Consider the timing. Make a plan.
