  • Targets: large roundworm, caecal worm, hairworm
  • Egg withhold: zero (0) days (manufacturer)
  • Sizes on this listing: 250ml and 500ml

Before using

  • Read the pack you receive first

What Vetafarm lists it for

Simultaneous treatment of sensitive strains of the three most important intestinal worms in laying hens:

  • Large roundworm (Ascaridia galli)
  • Caecal worm (Heterakis gallinae)
  • Hairworm (Capillaria spp.)

Worms spread bird-to-bird via the fecal-oral route and through secondary hosts like earthworms and slugs. Regular treatment every three months helps with parasite control.

How to use | Manufacturer directions

  • Dilute at 50 mL solution per 1 L of drinking water
  • Repeat treatment once every three months (4 times per year)
  • Withhold water from birds 2 hours before nightfall
  • Supply medicated water the following morning
  • Replace with fresh water once consumed or after 8 hours
  • Discard leftover medicated water and rinse drinkers

Best results (Vetafarm): Use drinkers the flock already knows. Avoid cold or wet days when water intake drops. Do not treat in extremely hot weather.
