Technical Abstract: Technical Abstract: High levels of anthelmintic resistance in gastrointestinal nematodes (GIN) of small ruminants have created the need for alternative approaches to parasite control. Copper oxide wire particles (COWP) have proven effective in decreasing GIN infection in lambs. However, the risk of copper toxicity has dictated a need for safe guidelines for its use. Small doses have been used in weaned lambs every six weeks until market age without risk of copper toxicity. Copper absorption and toxicity to this mineral have been described. A description of a commercially available product and its use has been outlined. COWP should not be used when other sources of dietary copper are available, in areas of low soil molybdenum or high copper, in sheep grazing pastures fertilized with poultry waste (high in copper), all of which may augment copper toxicity, or in breeds sensitive to copper toxicity.
