Abstract
In the farms of the Udmurt Republic, the most common endoparasites of cattle are Fasciola hepatica, Chabertia ovina and Haemonchus contortus and their association. Feces samples were taken individually and examined by flotation and sequential swabs. The therapeutic efficacy of anthelmintic drugs has been studied in 780 cows. Animals’ infection rate was determined by triple helminthocoproovoscopic examination of fecal samples by flotation and sequential washing before and after antiparasitic treatments (15, 30 and 90 days after deworming). The high degree of cattle infection in various regions of the Udmurt Republic with fasciolosis and strongilatosis of the gastrointestinal tract is due to optimal climatic conditions for the regular transmission of the pathogen to susceptible animals. The therapeutic efficacy of anthelmintic drugs has been studied in 675 cows, which were divided according to the principle of analogues into groups consisting of 45 animals. According to the results of our studies in case of nematode monoinvasion, the most effective antiparasitic drugs are closanthin 20 % (the cost of one dose per animal is 77 rubles) and ivermectins (the cost of deworming per animal does not exceed 40 rubles). Analyzing the extenseffectivity of the studied anthelmintic drugs, we found that closantin 20 % at a dose of 1 is the optimal drug in terms of efficacy and cost for monoinvasions (ID – 100 %) with fasciola or strongilates of the gastrointestinal tract, and their association (ID – 93.3 %), 1.25ml / 50kg of animal weight.
Highlights
In order to implement the Federal Law “On the Development of Agriculture”, the Government of the Russian Federation has been given the task to increase the productivity of animal husbandry, and obtaining of quality products simultaneously
The dominant position is taken by strongilatoses of the gastrointestinal tract
The high degree of invasion can be explained by the fact that, firstly: the population of adult animals in the strongilates epizootic process is gastrointestinal tract as the primary source of invasion pathogen, and secondly: the biological cycle of the pathogen depends on conditions of environment, which are quite favorable for geohelminthes in the Republic
Summary
In order to implement the Federal Law “On the Development of Agriculture”, the Government of the Russian Federation has been given the task to increase the productivity of animal husbandry, and obtaining of quality products simultaneously. During the planning of animal's deworming, it is necessary to take into account that as a result of complex methods to combat parasites of cattle, it is necessary to achieve complete elimination of helminths, and their metabolic products from the host organism. The choice, in this case, should be based on high effectiveness and on the safety of drugs, which, in most cases, are quite toxic. Over 2.000 anthelmintic drugs are used in world veterinary practice in different dosage forms [1, 3,4,5,6,7,8,9,10]
