Effectiveness of drugs in sheep melophagosis

The purpose of the study is to analyze the effectiveness of insecticides used in sheep melophagosis. Objectives of the study: to compare the effectiveness of drugs of various chemical groups and methods of their use in sheep melophagosis. One of the most important factors in the growth of animal productivity is the implementation of therapeutic and preventive measures for parasitic diseases. Of the infestations, melophagosis is often found in sheep, causing significant damage to the industry. With an intense lesion (more than 100 parasites per animal), body weight decreases by 8-10 kg and feed conversion worsens. The damage to sheep farming from the loss of meat productivity is estimated at millions of rubles per year. The shearing of wool decreases by 0.8 – 1.0 kg per sheep, its quality decreases. Various means and methods are used to treat sheep with melophagosis. Single treatment of sheep with Cyflunite provides 100% protection of sheep with melophagosis for 30 days. Cyflunite Flock also had 100% effectiveness and only on the 42nd day after treatment showed a slight decrease in insecticidal action. The extensivity of Ivermek was 100%. Merodok after a single injection showed 100% therapeutic efficacy and contributed to the complete liberation of sheep from bloodsuckers, and the period of protection from invasion was more than 30 days. When using Iversan, after 28 days, all sheep were completely free of bloodsuckers. Upon further observation, no bloodsuckers were found on sheep after 56 days. The effectiveness of the drug Delcid® 7.5 7 days after application was 100%. Bayofly pour-on and Dectomax also showed a 100% result. Monizen forte, with a single subcutaneous injection, provided 100% extensional and intensive efficacy.
