Tactical treatment with copper oxide wire particles and symptomatic levamisole treatment using the FAMACHA© system in indigenous goats in South Africa

摘要: Haemonchosis is considered to be the most economically important gastrointestinal disease of small ruminants in tropics and subtropics. However, chemical anthelmintics, which were mainstay control, have been compromised by a high prevalence resistance worldwide. Copper oxide wire particles (COWP) shown anthelmintic effects, but few studies examined their use under field conditions. The COWP was therefore evaluated as tactical treatment indigenous goats raised communal farming conditions Bergville, KwaZulu-Natal Province, South Africa. At beginning summer rainfall season (October 2007), faecal egg counts 172 female belonging 15 farmers determined this sampling continued every four weeks until second week January 2008. within each herds ranked according for week. sequentially paired off ranking starting with those highest counts. One goat from pair randomly allocated treated or control group. Two later, 4 g bolus administered Faecal carried out on two following treatment, then proceeded October Except six-week period prior administration COWP, FAMACHA© system symptomatically 12 mg/kg levamisole when anaemic. percentage reduction count due 89.0%.
