The in vitro anthelmintic effect of the extracts on Haemonchus contortus (H. contortus) three forage species tropical dry forest is known; however, there no information about effects extract partitions, nor their chemical composition. objectives this study were to evaluate ovicidal activity H. partitions Gliricidia sepium, Leucaena leucocephala, and Pithecellobium dulce, identify compounds pres...

Copper oxide wire particles (COWP) have been used to reduce infection of Haemonchus contortus in hair breed lambs in southeastern USA without signs of copper toxicity. However, copper sensitivity among breeds and regions varies. The objective was to determine the effectiveness and safety of COWP in lactating Polypay ewes and their offspring grazing alfalfa/bluegrass pasture in a rotational graz...

Haemonchus contortus is one of the most important parasitic nematodes of small ruminants around the world, particularly in tropical and subtropical regions. The control of haemonchosis relies mainly on anthelmintics, but the excessive and prolonged use of anthelmintics is causing serious drug resistance issues in many countries. As benzimidazole (BZ) anthelmintics have been broadly used in Chin...

CONTEXT The failure of modern anthelmintics to control nematode parasites of sheep and goats is a reality on many farms in the tropical/subtropical regions of the world. This necessitates chemotherapeutic control alternatives and plant secondary metabolite with activity is one of those potential solutions. OBJECTIVE This study was design to evaluate the efficacy of solvent: solvent fractions ...

During a survey of the parasites of antelope in the Bontebok National Park, Swellendam, Cape Province, specimens of Haemonchus contortus with exceptionally long spicules were recovered from 5 out of 8 bontebok, Damaliscus dorcas dorcas, and 3 out of 5 vaal ribbok, Pelea capreolus, but not from 4 springbok, Antidorcas marsupialis. Typically, H. contortus has spicules 0,466 +/- 0,085 mm long, but...

Gastrointestinal nematodes are a significant concern for animal health and well-being, and anthelmintic treatment is mainly performed through the use of chemical products. However, bioactive compounds produced by plants have shown promise for development as novel anthelmintics. The aim of this study is to assess the anthelmintic activity of protein fractions from Spigelia anthelmia on the gastr...

Present study was planned to screen locally available tanniferous tree leaves for their chemical composition, presence of condensed tannins (CT), potential source of CT and suitable leaf meal mixture (LMM) was formulated for incorporation in the densified complete feed blocks (DCF). Two types of blocks (with and without CT; CT-DCF and DCF, respectively) were formulated and prepared. Twelve adul...

The seasonal incidence of helminth infestation on a farm in the Transvaal Highveld was determined by the slaughter of tracer lambs exposed on pasture for periods of approximately 6 weeks. Haemonchus contortus, the most prevalent nematode, was recovered in the greatest numbers from January--May 1974. Peak counts of Ostertagia circumcincta were made during March and April 1974 and in January 1975...

<p><strong>Background. </strong>The edible mushroom <em>Pleurotus ostreatus</em> is a potential alternative for the control of gastrointestinal nematodes due to their nematoxins and secondary metabolites. <strong>Objective. </strong>To evaluate <em>in vitro</em> anthelmintic activity hydroalcoholic extracts mycelium, basidiomata spent substr...
