Controlled Epizootic Process at Fasciolese

Abstract

Analysis of veterinary reporting in the Tver Region in recent years allows us to conclude that the epizootic situation currently prevailing in the main helminthiasis of cattle has a persistent tendency to increase. Fascioliasis is one of the most common parasitosis that cause significant damage to cattle breeding. In the North-Western region, which belongs to the zone of periodic outbreaks of fascioliasis, invasion of Fasciola hepatica – occurs several times more often than in regions located in areas of insufficient moisture, in places that do not cover swampy and damp pasture areas, stagnant and low-flowing reservoirs. The extensinvasiveness of cattle in areas of excessive moisture can reach 90–100%. Based on the analysis of the reporting of this region, it can be noted that the epizootic process in fascioliasis is manageable, not only at the level of the economy, but also at the level of the whole territorial-administrative entity. The reporting data also confirm that the damage caused by fascioliasis consists of death, forced slaughter, culling liver affected by helminths, a 20–50% decrease in dairy and meat productivity, loss of breeding values and sexual activity of breeding bulls, a decrease in product quality and its energy value. A planned study of Santel's broad-spectrum angelmintic confirmed its following advantages compared to basic drugs: Santel has a long-lasting effect, which makes it possible to minimize the multiplicity of treatments; it is equally active against both preimaginal and imaginal forms of helminths (which allows significantly reduce the invasiveness of animals and prevent the spread of the pathogen in the external environment); convenient to use, taking into account the individual status of the animal (age and weight).
