Measures to Control Haemonchus contortus Through Plant Mediated Green Technology

Abstract

Haemonchus contortus is the most important parasite of the small ruminants. It causes diarrhea, bottle jaw, and edema, leading to anemia as a result, the production of milk and meat is reduced, causing significant economic and productive losses for people who are entirely dependent on livestock for their livelihood. Conventional methods such as pasture management and chemical anthelmintics are not very efficient against this problem, as the widespread use of chemical anthelmintics has led to the emergence of drug resistance. Therefore, it is essential to identify novel effective anthelmintics against drug-resistant strain. Plant-mediated anthelmintics are good alternatives against H. contortus and arise the interest of several researchers worldwide. This article extensively reviews the present state of knowledge regarding various plant extracts and their derivatives used against the gastrointestinal nematode H. contortus by several researchers.
