Replacing Resistant Worms

Researchers in Argentina replaced ivermectin-resistant worms (Cooperia spp.) with susceptible worms. After two production cycles, the clinical efficacy of ivermectin improved from 73% to 99.4%, while the absolute efficacy improved from 54.1% to 87.5%. No clinical signs of parasitism were observed in the beef herd, after parasite-free heifers had been inoculated with infective worm larvae (40,000 or 30,000 L3 Cooperia). "Low parasite refugia at the end of the summer is key to this approach," according to the researchers. Read abstract in Veterinary Parasitology, November 2017

Effects of Selective Deworming

A 3-year study (2006-2008) was conducted at the Appalachian Farming Systems Research Center in Beaver, West Virginia to determine the effects of selective deworming on performance and parameters associated with gastro-intestinal parasite management. Suffolk and Katahdin wether lambs and Boer wether kids were finished on a mixed sward of orchardgrass, red clover, and white clover, with and without whole cottonseed supplementation. After the initial deworming with a combination treatment, lambs and kids were dewormed only if they had FAMACHA© scores of 3 or greater. FAMACHA© scores were determined bi-weekly. Suffolk lambs had a higher average daily gain (ADG) than Katahdin lambs. Goat kids

Second Fact Sheet in Series Published

The second fact sheet in the Best Management Practices to Control Internal Parasites in Small Ruminants series has been published. The second fact sheet discusses the potential use of copper oxide wire particles in parasite control programs. It was written by Linda Coffey, Sheep & Goat Specialist with NCAT-ATTRA. All of the Best Management Practices fact sheets will be written and reviewed by members of the American Consortium for Small Ruminant Parasite Control. Each review team will include a veterinarian parasitologist. Most of the fact sheets will be published in 2018. Once complete, the fact sheet series will serve as a invaluable resource for producers and educators alike. Download Co

New Fact Sheets from Australia

The Department of Primary Industries in New South Wales (NSW), Australia, has published several new fact sheets pertaining to internal parasites in small ruminants.

Survey To Determine Impact of VFD

Michigan State University Extension, in partnership with other Land-Grant Universities, is conducting a nationwide survey of food-animal producers to learn more about how the VFD rules that have been in effect just over a year have impacted animal agriculture. Managing the health of your flock/herd is a primary responsibility of all farmers. The Veterinary Feed Directive (VFD) rules that went into effect January 1, 2017 may have impacted how you manage flock/herd health. The rules limited the use of medically important antibiotics to disease prevention, control or treatment, and only when a veterinarian writes a VFD for their use. We would like to learn how those rules have affected your man

Video: Duddingtonia flagrans

Duddingtonia flagrans is a non-chemical biological control for the infective stages of parasitic GIN of grazing animals, which acts by substantially reducing the numbers of infective worm larvae (including multi-resistant larvae) emerging from manure onto pasture. When fed to animals, the thick-walled spores remain inert (having no effect within the host animal) and resist digestion, passing through into the manure. There they germinate and form trapping organs that capture, paralyze and consume emerging infective worm larvae (including multi-resistant larvae). Learn more by watching this video. "I have been told that the product should be available in the US sometime early 2018. Stay tune
