Abstract

Study of helminths occurrences and evaluation of anthelmintic efficacy in adult horses of Sabugi Valley Region - PB.The study aimed to identify the prevalence of endoparasitoses and evaluate the effectiveness of treatments for parasites in horses in stables and farms vaquejada in Region Sabugi Valley - PB. The horses were clinically evaluated and fecal samples analyzed by direct test, according to Gordon technique (1948) by the quantitative determination of eggs per gram of feces (EPG) of 30 fecal samples, and the results revealed six (20%) positive findings Strongyloides parasitism. Three antiparasitic therapies were adopted with the use of commercial chemotherapeutic vermicide action, larvicidal and ovicidal, administered orally, in horses with results positivized in Tests for parasites. Using three types of treatment: treatment I, with Febendazol use; treating II with ivermectin treatment and III with the use of ivermectin and pyrantel pamoate. Of treated animals demonstrated 100% efficiency, proven through coprológica evaluation, performed 30 days after the antiparasitic therapy adopted. Concluding that endoparasitismo Strongyloides is prevalent in horses, especially under semi management - intensive and that the occurrence of endoparasitismo in Haras and equine breeding farms to vaquejada in Valley Sabugi region - PB, demonstrates failure parasite control, attributable to empirical practices, as the repetitive use of certain anthelmintics principles.
