Evaluation of Anthelmintics Resistance Against Gastrointestinal Parasites Infection in Awassi Sheep in Jordan and The use of Alternative Herbal Anthelmentics

Abstract

This study aimed to uncover the prevalence of anthelmintic resistance in ovine gastrointestinal nematodes in middle and north Jordan and to check the in vivo anthelmintic efficacy of apple cider vinegar drench and ginger powder. For this purpose a parasitological study was designed, which used fecal egg count reduction test Two hundred seventy ewes were enrolled in this study, twenty sheep farms were enrolled in this study, which had concerns about anthelmintic efficacy. On each farm, 10 sheep were randomly allocated to one of six treatment groups and five for an untreated control group. Fecal samples were collected on day 0 and days 10-14 for worm egg counts and larval differentiation at 6:00 am at the time of milking. Based on the morphometric identification of larvae, Trichostrongylous 85% was the predominant species, Oestertagia 10% and Haemonchous 5%. There was resistant against all species in the used anthelmintic drug, the highest reduction was noticed in the Ivermectin group and the lowest reduction rate was noticed in albendazole groups. There was low resistance against ginger powder and apple cider vinegar which means that they have a strong anthelmintic effect against gastrointestinal parasites.
