In the rearing of livestock (pigs, sheep, cattle, horses, donkeys, storks, etc.), some livestock keepers only pay attention to the supply of sufficient water for livestock during the hot summer months, and do not attach importance to providing sufficient drinking water for livestock during the cold winter months. This practice is wrong. Because water is not a source of thermal energy in the body of a carcass, it is one of the components of the carcass and is the most basic medium for physiological and biochemical processes in the animal body. It is an indispensable chemical substance for livestock to maintain life. The study determined that the water content of livestock was 35% to 80%, that of adult animals was 55% to 65%, and that of tissue fluid and digestive juice was 99%. Water content in pigs accounts for about 55% to 65%.
Water has important physical and chemical effects on the digestion and absorption of any livestock, the transportation and utilization of nutrients, the elimination of metabolites in the body, and the regulation of body temperature. Although livestock can obtain moisture from feed, it can also meet the need of water through direct drinking water and metabolic water in the body. However, moisture and metabolic water in the feed are often insufficient, so in actual feeding, livestock must be given to livestock. Always add clean drinking water. The water requirement of livestock is relatively large, and there are also differences due to different types of livestock, age, season, production function, work intensity and feed types. In terms of pigs, when raw dry feed is fed, the ratio of water to water is about 1:3. It should be more in summer and less in winter. There are more sows and fewer pigs. Generally speaking, the water requirement for livestock to feed 1 kg of feed dry matter is: 7-8 kg for pigs, 2-3 kg for goats, 4-9 kg for cattle, and 2-3 kg for donkeys.
