Efficacy of a Natural Based Product (Wormokill) in Treatment of Gastrointestinal Nematodes of Sheep in Kenya

Abstract

Faecal egg count (eggs per gramme) reduction test was done on days 4, 8, 12 and 21 post treatment, respectively, to evaluate the efficacy of the natural product, Wormokill, in treatment of helmenthiasis in mature Corriedale ewe sheep. Levamisole HCl (Wormicide) was used as a positive control. Both Levamisole and Wormokill were orally administered as per manufacture's recommendation. Wormokill was effective both at 2 and 3-tablet dosage with a reduction of more than 90%. At this dosage, Wormokill was as effective as to Levamisole in treatment of helmenthiasis. Levamisole and Wormokill had similar residual effect at day 21 post-treatment. It is, therefore, concluded that Wormokill can effectively substitute Levamisole under field helminth control during low rainfall season. The choice of the drug should be price/cost-driven and contamination of animal products by these drugs should be emphasised.
