“When considering the nutritional needs of pigs, we often consider the following more common aspects, such as amino acids, metabolic energy, vitamins and minerals, but in fact, water is the most consumed nutrient in the pig's life. And we The management of pigs' drinking water is the least, and the study of water is also the least nutrient,†said Bob Taylor, a senior hog expert at South Dakota State University (SDSU). "Moreover, in the only study, the different types of drinking water equipment involved are also very few and very confusing."
“The feed intake and subsequent growth performance are all related to the amount of drinking water. Therefore, any factors that reduce or limit the amount of drinking water will lead to a decrease in the growth performance of the pig,†said Taylor.
How much water does the pig need for normal growth? The amount of water needed per day depends on the stage of production. The recommended amount of water for each stage is as follows:
(1) New weaned piglet - 18.9L/head/day
(2) Growth - Breeding pigs - 5.7L/head/day
(3) Pregnant sows and boars - 15.1 L/head/day
(4) Nursing sows - 22.7L/head/day
These numbers represent the amount of water the pig needs. However, the above figures do not include water used for cleaning and cooling, etc. The clean and cooling water accounts for about 28% of the total water consumption of the farm.
Studies have shown that pigs instinctively want to drink water all day long. In general, when using a nipple drinker, bred pigs and pregnant sows tend to drink most of their water between 3:00 and 9:00 in the afternoon, and smaller drinking water peaks between 5:00 and 11:00 in the morning. period. Nursery pigs drink most of the water between 8:30 am and 5:00 pm. The nursing sows must drink water all day long because of the need to produce milk.
“The importance of pigs’ drinking capacity is due to the fact that at the peak of drinking water, the pig farm needs to have enough drinking equipment so that all pigs can easily drink water during high water demand periods,†said Taylor.
If there are more than 10 nursery pigs or 15 pigs in each pen, two functional papillary drinkers should be provided. And, because dust, sediment, minerals, etc. may clog the waterer, Taylor said it is critical to check the nipple drinker daily to make sure it is working properly.
Nipple drinkers must be installed at the right height to maximize drinking water. The general principle is to adjust the height of the drinking fountain to the height of the shoulder of the pig. Taylor said, "If the installation is too low, although the pig will still try to drink water, the amount of intake can not meet the growth needs of the pig, so the feed intake and growth performance will still be affected. In particular, the sow is more It is so."
In addition, Taylor also pointed out that in order to ensure the intake of adequate drinking water for herds, another key factor is the water flow rate when the water is sprayed out of the drinking fountain. "If the water flow is too fast or too slow, the water pressure is too high or too low, it is possible to reduce the amount of drinking water. Therefore, it is very important to adjust the flow rate to the appropriate level."
The recommended flow rates for pigs of different stages of growth are as follows:
Nursery pigs - 250 to 500 ml/min or 1 to 2 cups/min;
Growing pigs - 500 to 1000 ml/min, or 2 to 4 cups/min;
Breeding pigs - 1000 ml/min or 4 cups/min.
“The amount of drinking water not only affects the growth performance but also reflects the health status of the herd,†said Taylor. For example, if the amount of drinking water in a pigpen declines for 3 consecutive days, or if the amount of drinking water in a day drops by 30%, this indicates that pigs in the pig farm are likely to have potential health problems. At this time, the staff responsible for the pigshed need to find out the reasons accordingly.
Taylor believes that “water is a key nutrient that is more easily overlooked by the breeder and has a major impact on every stage of pork production. Therefore, the breeder should provide the right amount of water and pressure, and allow the pig to drink water conveniently. ."
Therefore, in pig production management, not only do you have to pay more attention to feed and feeding equipment, drinking water and drinking water equipment are also very important. Only by paying more attention to these two aspects at the same time can pigs achieve high production performance.
