New Small Ruminant Specialist

Dr. Andrew Weaver has been hired as the new Small Ruminant Specialist at North Carolina State University. Dr. Weaver grew up in central Michigan and was active in 4-H. He is a graduate of Michigan State University, Virginia Tech, and West Virginia University. At WVU, his research and extension focused on utilization of genetic tools and management practices to improve parasite resistance, performance, and end product value of small ruminants in the Southeastern US. Dr. Weaver is co-author of the ACSRPC fact sheet on using crossbreeding and estimated breeding values to improve parasite resistance in sheep. He reviewed the upcoming fact sheet on on-farm selection. Andrew can be reached at (919

Comparison of FEC Methods

Measurement of fecal egg counts (FEC) is the standard approach for assessing strongyle-type parasite egg shedding in livestock and is the primary means for assessing dewormer efficacy. There are several fecal egg counting methods. They vary in sensitivity, accuracy, precision, and technical difficulty. Scientists compared three methods (modified Wisconsin 3-chamber, 3 chamber McMaster, and Mini-Flotac) in cattle, sheep, horses, and llamas. In both an egg-spiking study and clinical samples, the Mini-Flotac system recovered the most eggs and yielded the highest EPG (closest to the true value). For horses and llamas, both the Mini-Flotac and McMaster yielded significantly higher EPG than the W

Diarrhea Associated with Parasites

Australian researchers published a review article about "Diarrhea associated with gastrointestinal parasites in grazing sheep." Diarrhea is a common and widespread problem in sheep. In many places, it is a major risk factor for flystrike. Gastrointestinal parasites have long been recognized as a cause of diarrhea in sheep. Of the worm species affecting sheep, Trichostrongylus spp. and Teladorsagia are most commonly associated with diarrhea. In young sheep, Nematodirus spp. may be associated with diarrhea. Haemonchus contortus does not cause diarrhea. Diarrhea associated with large worm burdens is managed through integrated parasite management programs that combine chemical and non-chemical

Role of Fecal Egg Counts

The Role of Fecal Egg Counts in Sheep/Goat Health is the title of the most recent Timely Topic, published by the American Consortium for Small Ruminant Parasite Control (ACSRPC). The author is Susan Schoenian, Sheep & Goat Specialist for University of Maryland Extension. Since 2013, sixty Timely Topics have been published to the web site of the ACSRPC. Each article is written by a member of the consortium and covers a topic pertaining to internal parasite control in small ruminants.

Video: Learn to Use New Curriculum

Virginia State University has created a hands-on, innovative curriculum to teach youth about internal parasitism in small ruminants. The curriculum is entitled Goats, Grass, and Uninvited Guests. It was created by Dr. Chantel Wilson, a 4-H STEAM Specialist. On June 11, 2020, a Zoom webinar was held to teach educators how to use the curriculum. The webinar was recorded, and the recording has been uploaded to YouTube. https://youtu.be/eApjdehYNLY
