Organic agriculture is an important area of high-quality food production and one of the stages of transition of agricultural production to green economy rails. At the moment, assortment on the Russian market of organic products is limited and there are no meat products in general. The aim of this study is to analyze the state of domestic pig breeding and the possibilities of conversion a certain segment of the industry to organic production. The methodological basis was the results of researches by domestic, foreign scientists, as well as our own studies. In the course of the work, general methods of scientific knowledge were used, which ensured reliability of the obtained results. Taking into account global trend towards healthy nutrition, Russian pig breeding has all prerequisites for conversion to organic production. Due to the high marginality of organic pig breeding, the presence in Russia of large labor and land resources suitable for organic production, there are all the prerequisites for organic pork to enter the world agrifood market. The implementation of this direction will require small business development, creation of a certification system for meat and meat products, training of qualified organic zootechnicians, as well as development and improvement of technologies.

Water is an extremely important element of metabolism in the body of pigs during ontogenesis. It acts as a transport and solvent medium for nutrients and waste products; improves the digestive system; provides a normal balance of electrolytes and mobility of joints; regulates body temperature; serves as a conductor of biochemical reactions. Pigs' need for water depends on many factors, including feed type, ambient temperature, and general health. Observations of the water consumption of pregnant sows indicate that the ratio of water and feed is stable in sows of the first and second farrowing, and water consumption increases further with each farrowing. The lactating animal should consume up to 40 liters of water per day. In weaning pigs and pigs for fattening, the maximum consumption is noted at the beginning and at the end of the period. Ethological observations have found that animals imitate each other when drinking, showing a herd reflex. With population increase in the group, water consumption increases. The dynamics of the process is influenced by feed type and feeding method. Lack of water leads to dehydration, which affects the behavior of pigs.
