Abstract:
Digestive helmints represent an important cause of the equine pathology, among these ones the most representative are the nematodes, from the Strongylidae family, Parascaris equorum and the cestodes such as Anoplocephala perfoliata. The measures to control these parasitosis are mainly based on regular deworming programs using different antiparasitic compounds. There are numerous studies, both nationally and internationally certifying a wider or narrower spread of resistance to some of the substances used for this purpose, especially in some species strongyls and other digestive helminths. The efficacy of treatment with products used in this study was tested on a herd of 56 horses copies of the territory Iași, Suceava, Bacău and Neamț, and the test used was the FECRT. The results showed a high efficiency of all three antiparasitic substances. In the case of ivermectin, FECRT average values were between 98.33% and 100%, for fenbendazole average was 97.11% and 98.21% for pyrantel. Thus, it found a high degree of safety regarding installation chemoresistant, at least for a certain period.
