Sable is considered a symbol of Russia. Animal furs were obtained by hunting. This was the main reason for the decrease in the number of the animals, which was almost exterminated. This situation was changed by hunting scientists who started breeding it in nurseries and releasing it. Russia is a leading country that supplies furs to the world market. It is important to design a sable farm correctly, taking into account scientific developments in achieving economic profit without disturbing the animal population. The most widespread technology is the breeding of ground-type cellular. However, this technology has a number of disadvantages. Therefore, the development of optimal technology for breeding with maximum economic effect and low costs of human labor is an urgent problem in the fur industry. (Research purpose) The research purpose is in conducting an analytical review of existing technologies for breeding sables and develop a multi-level optical-electronic system for monitoring the vital activity of sables in underground cell content. (Materials and methods) The article considers the main advantages and disadvantages of existing technologies for keeping and breeding sables. (Results and discussion) Authors propose a technology for underground cell keeping of sables with automatic control of microclimate and animal life in order to improve the quality of furs and reduce labor costs. The article determines the possibility of implementing optimal conditions for the normal life of sables not only in the North, but also in regions with high temperatures. (Conclusions) The article presents a scheme for a multi-level underground sable farm of a cellular type with optoelectronic control of the microclimate and vital activity of animals. The article presents an analytical description of the main parameters and the algorithm of operation of a multi-level optical-electronic system for monitoring the vital activity of sables.
