The Landscape-Ecological Peculiarities of Spreading of Dicrocoelium Lanceatum Stiles Et Hassal, 1896 Species among Small-Horned Domestic Animals in ihe Caucasus (Territory of Azerbaijan)
Abstract
The development of livestock breeding in Azerbaijan and the production of ecologically clean livestock products have always been in the center of attention of the country's leadership. In the Caucasus region (territory of Azerbaijan), where livestock farming is widely developed, protection of small ruminants from pathogens of infectious and invasive diseases, especially helminthic diseases, which cause serious economic damage to their development and productivity, is of great scientific and practical importance. It is known that helminthic diseases reduce animal productivity in all indicators, increase the number of cases of infertility, calving and death of young animals.
Implementation of effective control measures against these helminthoses, purification of nature and livestock farms from these pathogens, identification of foci of helminth pathogens spreading in nature and farms, as well as factors contributing to infection of animals in order to obtain abundant and sustainable ecologically clean products from animals are among the urgent and important tasks of the present day. One of the main causative agents of helminthic diseases widespread among small ruminants in Azerbaijan and causing serious economic damage to their productivity and sustainable development is D. lanceatum species. The study of the distribution of this helminth species in different landscape-ecological zones and seasons of the year in the Caucasus region, where livestock farming is widely developed, determination of its epizootological significance for other domestic animals in modern conditions and development of preventive measures against it on a scientific basis have not yet been fully developed.
Although research on helminths of livestock has been conducted in some areas of Azerbaijan, there is only brief information on this area in the Caucasus region, and until recent years this research had not been conducted extensively. Studies covering different physical-geographical and landscape-ecological conditions of the Caucasus are not sufficiently complete and most of the available data were obtained 30-60 years ago. Therefore, these data do not reflect the real situation in the modern era.
