Efficacy of Amprolium in Goat Kids

There is anecdotal information that amprolium is not effective in goats. In 2011, researchers from North Carolina State University conducted an on-farm study to evaluate the efficacy of two different doses of amprolium (Corid®) in goats heavily infected with pathogenic Eimeria species. Forty Boer goat kids (3-5 months old) with naturally occurring coccidiosis were randomly divided into two groups and treated orally with amprolium doses of either 10 mg/kg daily for 5 days (n=20) or 50 mg/kg daily for 5 days (n=20). E. christenseni was the most frequently identified coccidia species in a pooled fecal sample (52%). Oocyst per gram concentrations were significantly reduced on day 7 in the kid

All Worms All Day PART II

The 2017 Delmarva Small Ruminant Conference All Worms All Day will be repeated in 2018. Part II will be held Saturday, December 8 at the Western Maryland Research & Education Center in Keedysville, Maryland. The all-day conference will focus entirely on internal parasites. Speakers will be members of the American Consortium for Small Ruminant Parasite Control (ACSRPC): Susan Schoenian, University of Maryland; Dr. E. Nelson Escobar, University of Maryland Eastern Shore; Dr. Dahlia O'Brien, Virginia State University; Dr. Kwame Matthews, Delaware State University, and Dr. Niki Whitley, Fort Valley State University. Part III will be held in Virginia in 2019.

Turning the Forage World Upside Down

In the February issue of Hay & Forage Grower, I shared a story about Reed Edwards, a South Carolina farmer who had been growing sericea lespedeza hay for about 10 years. Edwards sold his hay about as fast as he could make it, mostly to customers with Boer show goats or dairy goats. As the situation currently stands, the condensed tannin found in forage legumes is like a wild horse waiting to be tamed. Once it is, the potential benefits are numerous for nearly every type of ruminant livestock class. Read article in Hay & Forage Grower

Timely Topics Being Published

Between August 2013 and November 2017, fifty-eight (58) Timely Topics were published to this web site. They were written mostly by members of the consortium and covered a variety of topics. We are in the process of publishing these Timely Topics as fact sheets that can be downloaded as PDF files. So far, eight Timely Topics have been published. Combination Treatments: The Time is Now (Ray Kaplan) When Deworming is Not Enough (Niki Whitley) Do's and Don'ts of FAMACHA scoring (Katherine Petersson) Disgusting Tapeworms! (Ann Zajac) Copper Oxide Wire Particles: Keeping It Safe (Lisa Williamson) Organic management management of internal parasites (Linda Coffey) Does Diatomaceous Earth Have a Ro

BioWorma - Duddingtonia

BioWorma, an innovative biological control product for parasitic nematodes (roundworms) developed by an animal health company in western Sydney, has finally been registered for use in Australia. Blacktown-based International Animal Health Products (IAHP) hopes BioWorma will be registered for release in NZ by next week followed by the United States by the end of April. The product is based on a strain of Duddingtonia flagrans, a fungus that occurs naturally in the environment and is found all over the world. The Duddingtonia flagrans spores are fed to grazing animals in feed supplements and have no effect on internal parasites within the animal.They pass onto pastures in the manure where they

Low Sensitivity of FAMACHA© in Growing Lambs

Brazilian researchers conducted a study to determine the sensitivity and specificity of the FAMACHA© system in growing lambs. Between 2015 and 2016, lambs aged 60–210 days on two sheep farms were evaluated at 15-day intervals using the FAMACHA© system. In total, 1591 assessments were analyzed. The highest percentage of larvae in the fecal cultures was for Haemonchus spp., (Ht) with an average of 78.5%. The sensitivity and specificity of the system were calculated according to two criteria: criterion 1, lambs classified as F4 or F5 were considered anemic (positive test) and those classified as F1, F2, or F3 were considered not anemic (negative test); and criterion 2, lambs classified as F3,

Does Lambing Treatment Benefit Lambs?

Anthelmintic treatments to ewes around lambing time, often with long acting products, have become common practice on United Kingdom (UK) sheep farms, but these treatments have also been shown to be highly selective for anthelmintic resistance in New Zealand and Australia, with field data supported by modelling results. British researchers conducted a study to determine 1) the effect of treating or withholding anthelmintic treatments and (2) the effect of treatment of ewes with a persistent or non-persistent anthelmintic, on early infection in lambs in the UK. Fecal egg count data for 10–16 weeks old lambs collected over a three year period (2012–2014) was analyzed. Teladorsagia (63%) was the
