Study on the inhibition effects of some Vietnamese traditional medicinal plants on egg hatching and larval movement of goat Haemonchus contortus

Nguyen Van Thanh, Nguyen Thanh Hai, Dam Quang Thai.

Abstract
Six traditional herbs which are well-known in Vietnam for their effect on endoparasite treatment, including: Achyranthes Bidentata Blume, Cassia Alata L, Embelia Ribes Burn, Ipomoea Hederacea Jacq, Leucaena Glauca Benth and Solanumtorvum Swartz were collected to evaluate the inhibitory effect on the egg hatching and larval movement of goat Haemonchus contortus. The aqueous extracts was made and diluted to 5 %, 10 % and 20 % to test. All of the herbs showed inhibitory efficacies at different levels, therefore explains their traditional application as the anti-parasite plants. Cassia Alata L and Embelia Ribes Burn showed the best effect on the egg hatching, while Achyranthes Bidentata Blume showed the best effect on the larval movement. In all of 6 tested herbs and 3 tested concentrations, only Ipomoea Hederacea Jacq and Leucaena Glauca Benth extracts at 20 % had good inhibitory effect (more than 70%) on both of egg laying and larval movement. This result suggests that Ipomoea Hederacea Jacq and Leucaena Glauca Benth extracts at 20% have the most potential to apply in the Haemonchus contortus treatment.

Key words: herbs, extracts, antiparasite, Ipomoea Hederacea Jacq, Leucaena Glauca Benth, goat, Haemonchus contortus
