Canadian Fact Sheets on Parasites

CEPOQ (Centre d'expertise en production ovine du Québec) has developed a series of seven fact sheets on internal parasitism management. The Canadian Sheep Federation provided funding for translation into English. The fact sheets are available for download as PDF files. 1. Selective Treatment of Parasitism: Clinical Indicators to Monitor 2. The Concept of Refugia 3. Deworming and Dewormers 4. Resistance to Dewormers 5. Fecal Monitoring for Gastrointestinal Parasites 6. Integrated Management of Gastrointestinal Parasites on Pasture 7. Optimal Pasture Management for the Control of Parasites The strategies in the fact sheets also largely apply to goats.

Joint US-Europe Meeting

The American Consortium for Small Ruminant Parasite Control (ACSRPC) is meeting jointly with COMBAR (COMBatting Anthelmintic Resistance). COMBAR is a European network that was formed in 2017 by 59 researchers from 29 countries. Its purpose is to develop a coordinated approach for dealing with anthelmintic resistance in dewormers. The ACSRPC was formed in 2003 for the same reason. The joint meeting will be held August 27-29, 2019, in Ghent, Belgium. The theme of the meeting is Anthelmintic Resistance in Ruminants: Who Cares? Participants will discuss the "who and how" of a shift towards sustainable management practices in ruminant parasite control. More than 100 people from all over the wor

Prevalence of Coccidia in Florida Goats

A study was undertaken to determine the prevalence and intensity of coccidia infection in Florida goats. Fecal samples from 277 goats from 11 farms were examined. Oocysts of Eimeria spp. were found in 97 percent of samples. Oocyst counts were much higher in kid goats (< 1 year) than adults: 13,229 vs. 2229 opg. Goats of the Nubian breed had the highest oocyst counts when compared to Boer, Boer-Spanish crosses, and Saanens. Nine Eimeria species were identified. Eimeria arloingi (91%), E. ninakohlyakimovae (82%), and E. alijevi (79%) were the most prevalent species. Mixed infections were encountered in most of the samples, with up to eight Eimeria species recovered from individual samples. The

New Buck Test Will Have Two Parts

The American Kiko Goat Association (AKGA) is partnering with Langston University (in Oklahoma) to hold a new buck test. The test will consist of two parts. The bucks will spend the first six weeks on pasture and the second eight weeks on feed in confinement. While in confinement, the bucks will be given a parasite challenge. The test is open to all breeds of goats. Breeders are expected to be able to nominate five bucklings. There is room in the test for 200+ goats. Bucklings must be born between December 15, 2018 and March 1, 2019. The cost will be $150 per buck. Bucks must be delivered to Langston on June 7. The test will end the week of September 26. Nominations are now open. Visit the t

Ram Test Nominations Due May 1

Virginia Tech's Southwest Ag Research and Extension Center Ram Test evaluates rams for parasite resistance, in addition to other traits. Nominations are due May 1. The test will begin on May 28, with delivery of rams to the test site. A sheep field day and educational program will be held on Friday, September 20, in conjunction with the sale of top performing rams. After a 3-week acclimation period, the rams will be evaluated for 70 days. Rams will have continuous access to high quality fescue-based pasture. They will be supplemented on daily basis with a concentrate. At the start of the test, the rams will also be administered a controlled dose of parasites Learn more

No Benefit to Feeding Fungus

A couple of studies reported in the scientific literature have failed to show a benefit to feeding nematode-trapping fungus (Duddingtonia flagrans). Studies involved dairy sheep in Switzerland, commercial sheep in Sweden, and lambs and kids in Germany. Dairy ewes in Switzerland A field study was conducted on three sheep farms in Switzerland to investigate the efficacy of Duddingtonia flagrans against naturally-acquired infections of gastrointestinal nematodes in adult dairy sheep. On each farm, the ewes were divided into two equal groups. One group received the spores for four months; one group served as a control. At an overall moderate infection level, in all farms D. flagrans did not have

Does Melatonin Trigger Hypobiosis?

In temperate climates, barber pole worms enter a period of inactivity (arrested development) during the late fall and early winter. Melatonin, with its release having a direct relationship to length of night, is highest during this period. Combining melatonin’s relationship to the seasons, along with research demonstrating that melatonin can inhibit locomotion in parasites such as Caenorhabditis elegans, it was predicted that melatonin is the cue for Haemonchus contortus to enter hypobiosis. University of Maine researchers designed an experiment to test the hypothesis that melatonin is the cue for H. contortus to enter hypobiosis. Effects of melatonin levels on development of H. contortus we
