Vet Parasitol. 2006;139:145-9 pubmed..001), but all concentrations were normal. Multiple doses of COWP were as effective as levamisole for control of H. contortus without risk of copper toxicity. ..
- Burke J, Morrical D, Miller J. Control of gastrointestinal nematodes with copper oxide wire particles in a flock of lactating Polypay ewes and offspring in Iowa, USA. Vet Parasitol. 2007;146:372-5 pubmed..There were no signs of copper toxicity in ewes or lambs. Alternative suppression of H. contortus infections may be necessary in ewes, but COWP was effective in H. contortus management for lambs. ..

Vet Parasitol. 2004;123:235-43 pubmed..PCV values were more favorable for lambs fed the higher level of supplement, especially when FEC were greater than 8000 epg. ..

- Burke J, Miller J. Control of Haemonchus contortus in goats with a sustained-release multi-trace element/vitamin ruminal bolus containing copper. Vet Parasitol. 2006;141:132-7 pubmed..GIN control did not persist more than 28 days. These studies suggest that TEB may be an effective means of GIN control in mature goats, but additional control measures may be necessary...
