Распространение и меры борьбы с кишечными цестодозами и стронгилятозами овец и коз в Дагестане

Abstract

The purpose of the research is testing the effectiveness of a new method of group deworming of sheep and goats with intestinal cestodosis and strongylatosis in the conditions of the Caspian region of the Russian Federation. Materials and methods. The experiment was carried out on sheep and goats of different ages infected with Strongylata spp., Nematodirus spp., Moniesia spp. in the form of mono- and mixed infections, in livestock farms which are unsuccessful for these infecions and at the laboratory for the study of infective diseases of farm animals and birds from the Caspian zonal NIVI (SRVI) – Branch of the Federal State Budget Scientific Institution "Federal Agrarian Research Center RD". For this purpose, in the Agricultural Production Cooperative "Tindi" located in the Babayurtovsky zone of transhumance pastures, 750 sheep and goats were selected, which were divided into two groups — experimental and control — before moving to summer pastures. The animals from the experimental group were subjected to the group dehelminthization by feeding Febtal granulate and Helmicide granulate preparations with food in combination with bentonite flour and sodium chloride. The control group animals were not given a drug mixture. During the experiment, sheep and goats were kept under identical conditions and were monitored daily. Before and after treatment, feces of animals were examined using the methods of Fulleborn, Weid and serial washing. Statistical processing of test results of anthelmintics was carried out according to the program "Biometry". Results and discussion. It was found that cestodosis and strongylatosis of the digestive tract of sheep and goats are widespread in the vertical zonality of the region. The highest infection rate was found in sheep and goats on the plain: respectively, Strongylata spp. by 26.04 and 19.3%, Nematodirus spp. by 28.0 and 24.6%, Moniesia spp. by 33.1 and 29.16%, and in the foothills – by 26.8 and 23.28%, 26.4 and 22.9%, 31.3 and 26.7%. Sheep and goats are infected with cestodes and strongylates to a lesser extent in highlands and mountains. The proposed new composition provides high efficiency in the treatment and prevention of gastrointestinal cestodosis and strongylatosis in sheep and goats. Thus, the dehelminthization efficiency was 96.0% with 64.0% infection of animals with Trichostrongylus spp. before the experiment. After the dehelminthization, Strongylata spp. eggs were detected in 6 % of sheep and goats. Efficiency against Nematodirus spp. was 98% and against Moniesia spp. was 100%.
