ЭФФЕКТИВНОСТЬ ЛЕЧЕНИЯ ДИКТИОКАУЛЁЗА ОВЕЦ

Dictyocaulosis remained one of the most prevalent helminthic infections in global sheep farming, inflicting substantial economic losses on the industry. The aim of the research was to study the efficacy of treatment methods for dictyocaulosis in sheep. The article presented the results of research on the efficacy of various antihelminthic drugs in the treatment of sheep dictyocaulosis caused by the nematode Dictyocaulus filaria. Diagnosis was carried out comprehensively, including epizootological data, clinical signs (coughing, emaciation, digestive disorders) and laboratory methods (helmintholarvoscopy according to Berman-Orlov). Three groups of sheep receiving Nilverm 20%, Santomectin and Ivermec were formed. The efficacy was evaluated according to the intensity and extensiveness of invasion, as well as extensiveness and intensiveness. Results showed that Nilverm 20% and Santomectin completely eliminated infestation by the 30th, whereas Ivermec provided 85-86% efficacy. Economic analysis revealed the highest profitability of Nilverm 20% application (91.2 RUB per 1 RUB of costs), followed by Santomectin (87.9 RUB) and Ivermec (83.2 RUB). The study demonstrated that timely and appropriate selection of antihelminthic drugs can significantly reduce the prevalence of dictyocaulosis in sheep herds. The study results confirmed the high efficacy of Nilverm 20% and Santomectin in controlling dictyocaulosis and emphasized the importance of proper selection of antihelminthic drugs to maintain animal health and improve flock productivity. The findings provided evidence-based guidance for veterinarians and sheep farmers in selecting the most effective and economically advantageous antihelminthic treatment for dictyocaulosis, ultimately improving animal health, productivity, and farm profitability
