WVU Professor Studies Parasites

West Virginia University Professor Scott Bowdridge has spent his entire adult life studying a parasite killing sheep. He may have just figured out how to stop it. Bowdridge studies Texel and Katahdin sheep as well as the all-white St. Croix sheep, which may hold the key to making other breeds resistant to the parasite threatening the country’s sheep.

Effect of Protein Supplementation

Brazilian researchers conducted an experiment to determine the effect of different levels of protein on parasite resistance and resilience of naturally-infected lambs. Sixty weaned Ile de France and Texel lambs (60 days of age) were divided into three groups, based on the level of protein in their concentrate ration: 1) low (8.5%); 2) moderate (15%); and 3) high (25%).

Effect of Se and Cu Supplementation

Brazilian researchers examined the protein profile of lambs experimentally infected with Haemonchus contortus and supplemented with selenium and copper. Twenty-eight crossbred Corriedale x Texel five-month old male lambs were used. They were stratified into four groups of seven animals each, based on treatment.

Monepantel Resistance After Two Years

A sheep farm in the Netherlands developed resistance to monepantel after using it for just two years. Monepantel (tradename = Zolvix®) is from a new class of anthelmintics called amino acetonitrile derivatives. It was first introduced in 2009 in New Zealand. It was introduced to the Netherlands in 2011. It is not available in the US.
