New Timely Topic: Worm-Trapping Fungus

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. Read Timely Topic Download PDF file

Undegraded Protein Has No Effect

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. Eighty-five twin/triplet-bearing ewes, which were indoors from mid-pregnancy, were randomly assigned to 4 treatment groups for the final 6 weeks of pregnancy. Treatments were silage plus one of two concentrates (differing in DUP concentration) offered at one of two feed levels. All ewes nursed two lambs when put out

Body Condition Scoring Sheep

Body Condition Scoring Sheep is another Facebook Live Video made by Dr. Reid Redden, Sheep & Goat Specialist at Texas A&M AgriLife Extension. It is a 7 minute 35 second video. Body condition scoring is an important part of evaluating small ruminants for their need for deworming. It is part of the Five Point Check©. Body condition scoring is also an important management tool for evaluating the nutrition program. https://youtu.be/gCu04ueCKOo

Diclazuril 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. Treatments of goat kids with diclazuril were effective against the three most predominant Eimeria species recorded in the study and also against other minor species found in fecal examinations. Even a single dose of 1 mg/kg resulted in an increase of growth rates in treated animals. Double and multiple dose treatments could be t

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®. Read full article in the Delmarva Farmer

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. Read article in Ohio's Country Journal
