Meningeal Worm Fact Sheet

Cornell University has published a fact sheet about the meningeal worm (Parelaphostrongylus tenuis), also called the deer or brain worm. Cornell has also developed a web page that has additional resources pertaining to the meningeal worm. For the past several years, Cornell has been evaluating treatment protocols for the meningeal worm. Small ruminants are abnormal hosts for the meningeal worm, which causes neurological symptoms in infected animals. Download Meningeal Worm Fact Sheet

DrenchRite© Test Currently Unavailable

The laboratory of Dr. Ray Kaplan at University of Georgia regrets to inform clients with small ruminants and exotic animals that we are currently on back order for the DrenchRite© resistance testing assay plates. Our producer in Australia is unable to make additional assay plates at this time. We hope to resolve this problem in the coming months, however, at this time we are unable to perform this resistant testing assay. We regret any inconveniences this may cause. The DrenchRite® Assay is a test performed to detect drug resistance in Haemonchus contortus parasites of small ruminants, camelids, and some exotic animals. Identifying the species of parasites infecting the animals is another k

Using a Smartphone to Count Fecal Eggs

Researchers at the Gluck Equine Research Center at the University of Kentucky have developed Smartphone technology for doing fecal egg counts. The technology has been licensed by Zoetis, which is focusing on small animals, while the University of Kentucky continues to fine-tune the technology for the equine industry. According to one of the researchers, a 2018 product launch is possible. The product takes a fecal sample, treats it with various chemicals that make the eggs glow green when illuminated with blue light, and then uses an iPhone to photograph and count the parasite eggs. The whole process takes less than five minutes. This technology can also identify parasite eggs of different pa

Are FAMACHA© & FEC Correlated?

FAMACHA© scores are a predictor of packed cell volume (PCV) and the need for deworming individual animals. They are a measure of resilience, whereas fecal egg counts (FEC) are a measure of resistance. Can FAMACHA© be used to select for resistance in a flock? Just how well do FAMACHA© scores correlate with FECs and other traits, such as body weight (BW) and age. Data from 1644 Katahdin lambs from 7 flocks were sampled at approximately 90 days of age. Data from 1295 Katahdin lambs from 6 flocks were sampled at approximately 120 days of age. Residual correlations among log-transformed FEC (LFEC), FAMACHA© scores, BW, and lamb ages at each measurement time were determined. At both 90 and 120 d

Three New Videos Added To Web Site

Links to three new videos have been added to the web site: "FAMACHA in a nutshell," "How to take samples for a fecal egg count," and "Jugular bleeding technique for sheep." The first two videos were funded by USDA's Research and Extension Initiative(grant # 2016-51300-25723). The third video was funded by the American Sheep Industry Association's Let's Grow Program.

Sericea Lespedeza Field Day

Sericea lespedeza (Lespedeza cuneata L.) is a high-tannin forage that has been scientifically proven to reduce parasite loads in sheep and goats. More recent research has shown that sericea lespedeza pellets may offer natural control of coccidiosis. Members of the American Consortium for Small Ruminant Parasite Control have led research efforts to determine the effects of sericea lespedeza on gastrointestinal parasitism in sheep and goats.

Comparison of Treatment Regimes

Refugia-based drenching regimes have been widely recommended to slow development of anthelmintic resistance, but there are few comparisons between different treatment approaches in the United Kingdom. Over a five year period, researchers compared efficacy of four different treatment regimes in anthelmintic (ivermectin) efficacy, body weight, and pasture contamination in lambs naturally-infected with gastrointestinal nematodes in Scotland. Regimes were whole flock treatment every 4 weeks (NST), targeted selective treatment (TST) based on performance, strategic whole flock treatments at predetermined times (SPT), and whole flock treatment when clinical signs were apparent (MT). Overall, both
