BioWorma 15lb Dewormer for Livestock, Horses and Cattle

BioWorma is a biological pasture dewormer for livestock, horses, cattle, goats, and other grazing animals. Unlike chemical dewormers, BioWorma targets worm larvae in animal manure before they can reinfect pastures — breaking the worm cycle at the source.

Its active ingredient, the naturally occurring fungus Duddingtonia flagrans, traps and consumes worm larvae in manure, including chemical-resistant strains. This makes it especially effective for herds where chemical dewormers alone are no longer working.

BioWorma works best as part of an integrated parasite management program. Use it alongside a standard dewormer to eliminate existing worms, then continue daily BioWorma feeding to prevent reinfection from pastures. Over time, this reduces the overall worm burden on your property, not just the animals.

Highly effective for young animals and breeding females. Regular use reduces pasture contamination, lowers reinfection rates, and minimizes the need for repeated chemical treatments.

Available in 15lb size. Exotic Animal Supply is one of only two authorized US sellers of BioWorma.

Instructions

Before starting BioWorma, treat animals with a suitable injectable, pour-on, or oral dewormer to eliminate existing worms. Once treated, move animals to low-worm pasture that has not been grazed by the same species for at least 6 weeks.

Thoroughly mix BioWorma into feed, supplements, premixes, or concentrates at 0.1 oz per 100 lbs of animal weight. Use the heaviest animal in the group to determine the correct amount, up to 1,200 lbs.

For animals over 1,200 lbs, add an additional 0.1 oz of BioWorma for each additional 100 lbs of bodyweight.

Administer the mixture daily under conditions conducive to parasitic activity. Continue daily feeding to minimize pasture infectivity and maintain low worm levels in your herd.

For best results, use BioWorma as part of an ongoing parasite management program rather than as a one-time treatment.
