Water in pigs accounts for 50% -85%, especially for newborn piglets. The water content is as high as 85% -90%. With the increase of age, the water content decreases. When the body weight reaches 100kg, the water content is 50%.
Daily water consumption of pigs
Growth stage / Daily water requirement (L)
Weaning: 12kg / 2.3 ~ 2.5
Growing pigs: 27 ~ 36kg / 3.2 ~ 4.5
Fattening pigs: 34 ~ 90kg / 4.5 ~ 7.3
Empty sows: 92 ~ 172kg / 5.4 ~ 13.6
Sow: Before farrowing / 13.6 ~ 17.2
Sow: Postpartum / 18.1 ~ 22.7
Note: The water demand is small in winter and the water demand is large in winter.
Many pig farmers believe that drinking fountains are now installed, and pigs are unlikely to be short of water. In fact, the problem lies in drinking fountains, which cause pigs to drink insufficient water and cause various diseases. Let's take a look at some common drinking fountain problems.
A. The selection is inaccurate. Commonly used are duckbill type, nipple type, and cup type. Many pig farmers do not understand the characteristics of drinking fountains, which are generally the same, of course, the effect is not good. Duckbill type is suitable for sows; piglets are suitable for nipple drinkers, and fattening pigs are suitable for cup drinkers.
B is not enough. Many people think that there are fewer pigs. One pigpen and one waterer is enough, and it also saves costs. In general, pigs drink a lot of water after eating, and one drinking fountain is obviously not enough when concentrated drinking. It is recommended that two drinking fountains be installed in each pigpen. If there are more than 10 pigs in a pigpen, two waterers must be installed.
C. The direction is wrong. It is wrong that the stem of the drinking fountain is wrong to the left, right, and down. Correct is up.
D. The position is wrong. Most drinking fountains are installed at the defecation area and are considered to be easy to drain. When the pigs drink water, they occupy the defecation position, causing the pigs to defecate randomly and vying for the drinking position. The correct position is 1.5 to 2 meters away from the trough.
E. Too high or too low. It is easy to be too high for piglets and too low for fattening pigs. The correct height should be parallel to the pig's head. For pregnant sows, the nipple valve port should be 70 to 90 cm above the ground; for lactating sows, the nipple drinker height should be 75 to 90 cm; the port of the drinker nipple in the nursing piglet should be 10-15 cm above the ground Office. When the pig's weight is 5-13g, 13-33kg, 33-56kg, more than 56kg and breeding herd, the recommended height of the nipple drinker when installed at a 90-degree angle to the wall should be 15.2-30.4 cm , 30 to 45 cm, 45 to 60 cm, 60 to 75 cm, 75 to 90 cm; and when it is at a 45-degree angle with the wall, a higher height is required.
F. The angle is wrong. The upturn is not right, neither right or left. It is true that the water fountain is facing down and 90 degrees or 45 degrees from the wall (mainly used for piglets).
G. Insufficient flow. Often, the water flow is insufficient due to blocked or broken drinking fountains, mainly due to the lack of regular inspection and maintenance. The standard is that the water output should be greater than 2 liters per minute under 2 standard water pressures. The pressure of the water dispenser is too high, it is easy for the water to splash out, and it will cause drinking water stress for the pigs, the piglets will be stung, and water will be wasted.
