The effectiveness of BioWorma® was assessed by total worm counts in tracer sheep placed in paddocks grazed by parasitized sheep which were fed a daily supplement with and without BioWorma® under group-feeding conditions.
Further proof of concept was obtained by assessing the worm burdens and weight gains of the parasitized sheep, as well as the number of anthelmintic (“salvage”) treatments required when fecal egg counts exceeded a threshold level. The studies were conducted in Australia across a range of climatic zones/seasons.
BioWorma® is a feed supplement that contains Duddingtonia flagrans, a nematode-trapping fungus. It was developed by an animal health company in Australia and has been licensed for use in Australia, New Zealand, and the United States.
