Regulating Factors the Number of the Population of Nematodes in Digestive System of Ruminants

The distribution of the nematode population in the digestive system of ruminants is not constant and varies depending on a number of exogenous and endogenous factors. In ruminants of Uzbekistan, 79 species of nematodes were found, including 62 geohelminths and 17 biohelminths. As intermediate hosts in biohelminths, the class of insects is presented. The nature of the distribution of the nematode population in space, bearing in mind their abundance in the external environment and the organism of the respective hosts, is directly dependent on the action of the contributing and limiting factors.
