Modern animal husbandry in Yakutia is represented mainly by private farms. One farm contains on average up to 20 heads of cattle. All labor-intensive processes are carried out manually. The stall period in the region is about eight months. Manure produced is briquetted and transported to nearby open areas. Due to the fact that farms are located in settlements, at present, measurable piles of fresh and dry manure have been accumulated around livestock buildings, and villages are surrounded by randomly arranged heaps. In spring, all this thaws and enters water bodies, pollutes the land, and harms not only the environment, but also human health. The danger of insufficiently treated litter-less manure is that it contains a huge variety of microorganisms, the so-called saprophytes. When they get into certain favorable conditions, some of them turn into pathogens of diseases such as anthrax, tuberculosis, tetanus, brucellosis, foot-and-mouth disease and even plague, which have a negative, severe and sometimes inevitably disastrous effect not only on animals, but also on humans. In this regard, we have presented developments to improve of technologies for the removal, collection and processing of the resulting litter-less animal manure.
