• Broodmares should be routinely wormed throughout the gestation period, but you should always seek advice from your vet or a suitably qualified person (SQP) first for advice on which wormers to use. This is to ensure that the wormer you use is licensed as safe to treat pregnant or lactating mares and young stock.  
  • The mare’s natural resistance to worms is lowered in late pregnancy, so it’s best to worm 2 – 4 weeks before she foals to ensure she isn’t carrying excessive worms and passing an increased amount of eggs in her droppings when the foal arrives. The eggs can develop on the pasture and may result in redworm infection for the foal.
  • Foals are born parasite-free with no immunity to parasite infection and internal worm burdens can lead to permanent damage. Therefore, it is essential that a worming programme is in place to protect the foal. As with any worming treatment, ask your vet or SQP about wormers safe for foals from the age of four weeks.
  • As the foal gets older and grazes more, the risk of parasite infection increases, so good pasture management with regular poo-picking helps to reduce the risks.
  • Foals are sensitive to wormer overdosing, so make sure that you accurately assess their weight before each dose to ensure the correct amount is administered.
