BioWorma® for Preventing Roundworm Reinfestation in Horses 

International Animal Health is proud to introduce the first products proven to decrease the reinfestation of roundworm larvae.


Bioworma products

BioWorma® or Livamol® with BioWorma® are not anthelmintics/dewormers.

Both products contain a natural fungus called Duddingtonia flagrans.

When fed to grazing animals the thick-walled spores pass through the digestive system, remaining inert (having no effect within the host animal) and out into the manure.

When the infective nematode/roundworm larvae become active within the manure, the fungus germinates, forming a fungal web that captures, paralyzes, and consumes the infective larvae.

As a result, the worm cycle is effectively broken.

Anthelmintic resistance has no effect on BioWorma.

BioWorma and Livamol with BioWorma reduce the number of gastrointestinal nematode (GIN) larvae on pasture, which is significantly greater than a chemical wormer can do within the animal.

International Animal Health Products (IAH – studies showed the average reduction for horses was 84%.

Efficacious in horses on:

Large strongyles (large red worms), including Strongylus spp., Triodontophorus spp., and Oesophagodontus spp.; small strongyles (small red worms or cyathostomes), including Cyathostomum spp., Cylicocyclus spp., and Cylicostephanus spp.; Stomach Hair Worm (Trichostrongylus axei); Ascarids (Parascaris equorum); Threadworms (Strongyloides westeri); and Pinworms (Oxyuris equi).

Over 20 years of development and 120+ studies confirm the efficacy of BioWorma.
