How do you get rid of worms in pastures?

Harvesting fields for hay is one way to open up those areas to heat and sunlight in order to kill parasite larva. Another option is to have long rest periods so that the parasites die before the sheep return to that field to graze. Parasites can also go into a hypobiotic or dormant state inside sheep or goats.

How can mowing pastures periodically help reduce parasites?

“Rotating livestock through different pastures helps to reduce parasite pressure by removing animals before parasite eggs hatch and larva are ingested,” Speir says.
