BioWorma FAQ

What is BioWorma?

BioWorma® is a natural biological control containing the fungus, Duddingtonia flagrans that captures and consumes infective worm larvae (including chemical resistant/anthelmintic multi-resistant larvae) within the manure of grazing animals. This breaks the re-infection cycle that sustains the worm population in grazing animals.

Livamol® with BioWorma® is a ready to use product that contains the fungus along with a nutritious blend of proteins, energy and polyunsaturated oils plus added vitamin and minerals which are all important for the development and maintenance of immunity of young, growing grazing animals.

Through good nutrition, these animals are better able to cope with parasitism and this has a positive impact on their resistance and resilience to worms.

Why can’t I get BioWorma concentrate?

BioWorma is formulated for supply as a manufacturing product to veterinarians, feedmills and premixers whereas Livamol with BioWorma is formulated for your personal use and is available to the end user market for addition to individual feeds.

How do I get my free faecal egg kit?

The free faecal egg kit is only available to our New Zealand and Australian customers (not available in the USA at this time) and can be acquired by visiting the Livamol with BioWorma product page.

Is BioWorma safe for my animals?

Yes, both products are safe when used according to the label directions. It is safe for farmers, animals and the environment. Safety was established through long-term high-dose (5 to 10 times dose) feeding studies.

Is BioWorma safe for pregnant animals?

Yes, BioWorma has no effect within the host animal meaning it is safe for all grazing animals.

Is BioWorma safe for lactating animals?

Yes, there is a nil meat and milk withholding period for Australia & New Zealand meaning the meat and milk of the grazing animals will always be safe to eat or drink.

Is BioWorma a pesticide?

The category BioWorma falls into depends on the regulatory arrangements in the various countries where it is registered. In Australia and New Zealand it is a veterinary medicine, in the US it is a feed-through biopesticide and in the EU (pending) it will be a feed additive.

What is the best way to start feeding BioWorma or Livamol with Bioworma?
  1. Treat animals with a suitable oral, injectable, or pour-on wormer/anthelmintic to rid the animals of worms, then begin administration of BioWorma®.
  2. Move the treated animals onto low worm pasture (that is, pasture that has not been grazed by the same animal species for a minimum of 6 weeks).
  3. The most worm-susceptible are young animals (from 3 months up to 18-24 months of age) and periparturient females (last month of pregnancy and while producing milk), as they are the most likely to have less resistance to worm infestation due to low immunity. Do not underestimate pasture contamination by adult stock, even animals with low faecal egg counts (FECs), considering the volume of faecal material adult stock place on pasture.
  4. Thoroughly mix BioWorma® with feed, feed supplements, premixes or concentrates, and commence daily administration of the resultant mixture to minimize pasture infectivity and maintain the low worm status of the animals.
  5. BioWorma® will begin to work within the first day and may be fed continuously when warm, moist climatic conditions are conducive to parasitic nematode activity.
  6. BioWorma® is for use during periods when conditions are conducive to larval development and transmission onto pasture at temperatures above 40° Fahrenheit (5° Celsius).
  7. Use BioWorma® in conjunction with the specified worm management strategy for your area by contacting your Veterinarian, Animal Health Advisor or Government Advisory groups for a strategic Integrated Parasite Management (IPM) plan. It is important to consider the principles of refugia.
  8. Periodically check the worm burden and monitor the effectiveness of the worm management system. Options include faecal egg counts (FECs), the faecal egg count reduction test (FECRT) and/or identifying worm species by using faecal larval cultures (FLCs). Re-treatment with an effective chemical wormer may be indicated (consult your Veterinarian).

Why does Livamol with BioWorma contain Cobalt sulphate?

Please follow this link for more information - Cobalt Sulphate is an essential trace mineral which is included at very low levels for nutritional purposes. In accordance with National Research Council recommendations: Cobalt sulphate is regarded as GRAS (Generally Regarded as safe) by AAFCO (American Association of feed Chemists & Officials)

Why can’t I spread BioWorma ontop of the faecal matter and pasture?

Bioworma and Livamol with BioWorma contain the active Duddingtonia flagrans. For the Duddingtonia flagrans to be active it relies on the activity of parasitic larvae which triggers sporulation of the Duddingtonia flagrans to create larvae trapping networks.
