Nematode parasite control practices of sheep and goat farmers in the region of Trikala, Greece.

Abstract

Information concerning worm control practices of sheep and goat farmers in the region of Trikala (central Greece) was collected through a questionnaire survey by visiting farms and interviewing farmers. Questionnaires from 57 farmers residing in 23 rural communities were collected. Anthelmintics were used by 89% of the farmers. On average, lambs, kids and goats were treated once annually, while sheep were treated either once or twice annually. Only 2% of farmers reported treatment of animals with anthelmintics when moving to new pastures. The most common broad-spectrum anthelmintics used were those belonging to the benzimidazoles and probenzimidazoles. Fifty nine percent of the farmers used the same anthelmintic group for 3 or more years and 34% used two or more anthelmintic groups in the same year. Almost all farmers reported estimating live weights for calculating anthelmintic doses through visual perception on the basis of an average weight (96%). Tablets and boluses were the most preferred anthelmintic formulation used by 96% of farmers. The selection of an anthelmintic was based for 58% of farmers on recommendation by a veterinarian and for 39% of farmers on the cost of the drug. The most common occasions for deworming the animals were at turn out (86%) and after parturition (31%). Only 6% of farmers reported deworming new animals before introducing them onto the farm. Farmers preferred to seek information about the use of anthelmintics and worm control strategies from veterinarians (63%) and other farmers (37%).
