Studying Parasites in Ohio

Brady Campbell is the program coordinator for the Ohio State University Sheep Team. Campbell's research is looking at which practices used singly or in combination will reduce worm burdens in sheep. His earlier research showed that delayed weaning reduced parasite burdens in lambs. Campbell is also looking at fall lambing and alternative annual forages for parasite control. Another of his studies is using an ear tag that monitors each animal’s activity, like a pedometer.

The Fungus is Coming!

Duddingtonia flagrans is a naturally-occurring fungus that traps and kills infective worm larvae. When it is consumed by grazing livestock, it reduces pasture infectivity; thereby, lowering fecal egg counts and worm burdens in livestock.

After more than 20 years of study, an animal health company in Australia has commercialized the fungus. It is being sold under the trade name BioWorma®.

Diclazuril Is Effective Against Coccidiosis

Spanish researchers divided 101 kids, 2-4 weeks of age, naturally-infected with Eimeria spp. into five treatment groups. Different doses (1 and 2 mg/kg) of diclazuril (Vecoxin®) were given at either 3 weeks of age (single treatment) or 3 and 5 weeks of age (double treatment). Fecal oocyst shedding and body weights were monitored at two week intervals for six weeks.

Effect of Undegraded Protein

Since maternal nutrition during pregnancy is a major environmental influence on fetal development with consequent effects on post-natal performance, Irish researchers hypothesized that the level of intake of digestible undegraded protein (DUP) by the dam in late pregnancy would impact on the effectiveness of the immune response by offspring to gastrointestinal nematode infection.

New Timely Topic

ACSRPC members Jim Miller and Joan Burke have written a Timely Topic about BioWorma®, the new worm-trapping fungus that has been approved for sale in the US. While distribution is still being worked out, product should be available sometime this spring and/or summer.

BioWorma® is a biological control agent against the immature (larval) stages of gastrointestinal nematodes in livestock feces. The primary delivery system is thoroughly mixing the fungal spore material into supplement feedstuffs for daily feeding.

New International Collaborator

For the past 30 years, Chris Lawlor has been the owner and manager of International Animal Health in Australia. He plays an active role in the day-to-day running of the business.

One of the products that International Animal Health markets is BioWorma®, a natural biological control that captures and consumes infective worm larvae (including chemical resistant/anthelmintic multi-resistant larvae) within the manure of grazing animals.
