Complex application of antihelmintic substances at mixed nematode-cestodes invasion of chickens

Before veterinary science a task stands on development of the modern effective systems of the integrated defence of poultry from endoparasites with the purpose of making healthy of poultry farming economies from mixed helminthiс invasions. Our work is devoted to researches of determination of efficiency of complex application of antihelmintic substances at mixed nematode-cestodes invasion of chickens. Determination of antihelmintic efficiency of medicinal substances at the mixed helminthisms was conducted in laboratory conditions on the laying chickens-hens spontaneously infested by nematodes and cestodes, namely, ascarids, capillaries and raillietins. Poultry of the first experimental group was given levamisole 10% with water at 20 mg of O.S. (operating substance) for 1 kg body weight singly, on the third day of the experiment poultry was given fenbendazole at 15 mg O.S. for 1 kg of body weight singly. Livestock of the second experimental group was given albendazole 10% according to the instructions for use. Poultry of the third group (control) did not receive preparations. According to the results the experiments of the extenseffectiveness of proposed method of application of preparations against mixed infectation in the first group was 100% in the 7th day of experiment already. In the second experimental group effectiveness of albendazole was 83.3%. The comparative estimation of efficiency of received results gives reason to consider that the proposed method of complex application of antihelmintic substances at the mixed nematode-cestodes invasion is high-effective and presents an alternative to the traditional method of treatment of invasion that expressed in the protracted application for poultry of antihelmintic.
