摘要: Anthelmintic resistance is very prevalent in ruminant strongyle populations, especially goats. Several occurrences of multiple anthelminthic resistances have been reported goat flocks throughout the world, including to most recent macrocyclic lactones. A faecal egg count reduction test was conducted detect ivermectin French flocks. Thirty goats per flock were randomly selected 22 and allocated into two groups 15 animals: an untreated control group ivermectin-treated (0.3 mg/kg BW os). Individual counts pooled larval cultures performed 16-17 days after anthelmintic treatment for treated groups. FECR’s calculated vs. one when <95/100, considered as indicative resistance. FECR results indicated absence nematode populations from all farms. The genera involved Teladorsagia/Trichostrongylus, Haemonchus Oesophagostomum/Chabertia types.
