3/4 of the pig body is water. Moisture is directly involved in the formation of cells and tissues of organisms. It is an important solvent, capable of dissolving and transporting nutrients and excreting metabolites; it is a coalescent of metabolites, and participates in reactions such as hydrolysis, redox and the like in vivo; it is a lubricant that can make joints move. Reduces friction and regulates body temperature to maintain body fluid and body osmotic pressure balance. Pigs that are hungry for a long period of time can still survive if they lose 40% of their body weight. However, if the water loss is 10%, the metabolic process will be destroyed, and 20% loss of water may cause death.
Under normal circumstances, the water requirement per kilogram body weight of suckling piglets is: 200 grams in the first week, 150 grams in the second week, 120 grams in the third week, 110 grams in the fourth week, and 100 grams in the fifth to eighth week. For growing and finishing pigs under the condition of unlimited feed intake and drinking water with automatic drinking fountains in the automatic feeding trough, during the period from 10 to 22 weeks of age, the average ratio of water to feed is 2.56:1 for non-pregnant young sows drinking about 11.5 kg of water per day, and the pregnant sows Increased to 20 kg, nursing sows more than 20 kilograms.
The correct water supply method: separate the feed water, feed dry material (compound feed or full-grain pellet feed), if you use self-mix feed the pig, wet mix can be used (feed water ratio is 1:1 to 1.5), feed enough Drinking water.
