First Fact Sheet in Series

The American Consortium for Small Ruminant Parasite Control (ACSRPC) is publishing a fact sheet series entitled "Best Management Practices for Controlling Internal Parasites in Small Ruminants." The first fact sheet has just been published and is now available for download. It covers the role of pasture management in parasite control and was written by Heather Glennon from the University of Mt. Olive. All of the Best Management Practices fact sheets will be written and reviewed by members of the consortium. 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 f

1st Broad-Spectrum Combination Drench

In October, VIRBAC Australia introduced Tribectin™, the world's first broad-spectrum combination drench. Tridectin™ is a new class of combination drench than contains three powerful broad-spectrum actives: moxidectin, albendazole, and levamisole. Tridectin™ has a registered claim to will kill triple-resistant worms and monepantel (Zolvix®)-resistant worms. According to the company's web site, it kills moxidectin-susceptible strains of barper pole worm and small brown stomach worm for 14 days. The product has a wide safety profile, with a meat withdrawal of 7 days. Tridectin™ is not available in the US. No combination dewormers are currently available in the US for small ruminants.

Project to Validate FEC EBVs

Since the mid-2000’s, the National Sheep Improvement Program (NSIP) has been providing estimated breed values (EBVs) for parasite resistance. These EBVs have been for fecal egg count (FEC), an indicator trait of resistance. FEC EBVs have allowed producers to select for superior individuals in reducing parasite burden. But do they work? With the rise of anthelmintic resistance in parasite populations, genetic selection for parasite resistance has been suggested as a means to ensure small ruminant sustainability. Breed differences in parasite resistance have been well established. Caribbean hair sheep (St. Croix, Barbados, etc.) develop a strong immune response which inhibits larval establish

ACSRPC Honors One of Its Own

At their last meeting, the membership of the American Consortium for Small Ruminant Parasite Control (ACSRPC) recognized Jim Miller for his "service and dedication to industry, academia, and farmers in the control of internal parasites in sheep and goats." Jim recently retired from Louisiana State University. He is a veterinarian parasitologist and founding member of the American Consortium for Small Ruminant Parasite Control (L-R) Ray Kaplan, Joan Burke, Jim Miller, and Tom Terrill

Do Worms Predispose Ewes to Mastitis?

Greek researchers studied the possible role of gastro-intestinal nematode infection in predisposing ewes to mastitis during the lactation period. In a study involving twelve parasitized ewes (FEC >500 epg) and twelve unparasitized ewes (FEC <20 epg), the researchers found a positive correlation between intestinal helminth counts and udder pathology scores, leading them to conclude that gastrointestinal trichostrongylosis and particularly Teladorsagia infection might lead to clinical mastitis.
