Etude du mode d’action des tanins condensés sur le parasite Haemonchus contortus.

Abstract : In the West Indies the breeding of small ruminants is very widespread. The proliferation of gastrointestinal nematodes is the main factor behind production reductions in small ruminants. After ingestion, the parasites migrate into the abomasum and cause weight loss, late growth, diarrhea which can be severe and death. Faced with the resistance of nematodes to anthelmintic molecules, such as benzimidazoles (100% resistance) and others, the use of active ingredients from local plants is an alternative. Indeed, the effectiveness of condensed tannins has been demonstrated on the rate of development of the parasite and the rate of excretion of eggs. We studied the mode of action of condensed tannins on the development of the H. contortus parasite in small ruminants, taking as a model the plants Leucaena leucocephala, Cajanus cajan, Manihot esculenta consumed alone or as a mixture. The methodology implemented made it possible to demonstrate, at the concentrations tested, that the development of H. contortus eggs is affected when animals have been treated with TC plants.
