ACSRPC Fact Sheet Series Completed

The fact sheet series, "Best Management Practices to Control Internal Parasites in Small Ruminants" has been completed. Each fact sheet was written and reviewed by members of the American Consortium for Small Ruminant Parasite Control (ACSRPC).

The first fact sheet (on pasture management) was published December 2017. The last one (periparturient egg rise) was published April 2020. Collectively, the fact sheets represent a valuable resource that should help producers better manage parasitism in their sheep, goats, and camelids.

Links to all of the fact sheets are available at https://www.wormx.info/bmps.

A Remarkable Recovery

Dr. Tom Terrill is the Coordinator of the American Consortium for Small Ruminant Parasite Control (ACSRPC). He is a leading researcher on sericea lespedeza, the warm season legume that reduces barber pole worm infections in sheep and goats. Read about Tom's remarkable recovery from Covid 19.

An In-Depth Look at Ivermectin

In April, several media outlets reported the success of an in vitro study conducted in Australia regarding the antiviral effects of ivermectin on the virus that causes COVID-19. After the story about ivermectin broke on social media, some farm stores removed ivermectin from their shelves, in fear of people buying it to self medicate.

Ivermectin was discovered in 1975. It became commercially available in 1981 and soon became the top-selling veterinary drug in the world, earning the title of “wonder drug.” It has been used to deworm small ruminants for decades.

Free Fecal Egg Count Analysis

Please view this flyer to learn about free fecal egg count analysis to assist with selective breeding for resistance to gastrointestinal nematodes.

This opportunity is available to National Sheep Improvement Program (NSIP) members either in or marketing animals to the Northeast who want to generate Estimated Breeding Values (EBV) for parasite resistance. Non-NSIP members living in New England, NY, NJ, PA, WV, MD and DE are also eligible for this program. More specific criteria are listed on the flyer.

For more information, send an email to urisheepandgoat@etal.uri.edu.

Please Take Survey

The Northeast Small Ruminant Parasite Control Program is conducting a survey to obtain current, baseline information on sheep and goat parasite control concerns and practices. The information obtained will be extremely valuable in continuing to identify needs and develop research and education programs for small ruminant producers living in the Northeast US or that buy animals from or sell animals to Northeast producers. The survey should take between 10 and 20 minutes to complete.

Selection for Parasite Resistance
by Joan Burke, USDA ARS

In domestic populations, animal welfare is of high importance, and it is desirable to select against parasite susceptible animals before we see poor performance and death losses. Fortunately, the ability of an animal to resist parasite infection is moderately heritable, and resistant parents will most likely have resistant offspring.

American Consortium for Small Ruminant Parasite Control (ACSRPC)

The ACSRPC is a group of scientists, veterinarians, and extension specialists dedicated to helping small ruminant producers control GI parasites in their flocks and herds. The consortium was formed in 2003 in response to the critical state of the small ruminant industry associated with the emergence of anthelmintic resistant worms.
