The importance of water in pig farming

Abstract

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.
