Drinking light salt water to prevent colds can effectively supplement potassium and sodium ions. The weather is hot, sweating a lot, and there is a lot of water and salt in the body. Therefore, it is necessary to drink light salt water regularly to supplement salt, and the salt should be appropriate.

Feeding salt has many advantages. Salt is called sodium chloride for short, and its main chemical components are chlorine and sodium. These two elements are indispensable in pigs. They mainly exist in extracellular fluid and play a very important role in maintaining the stability of osmotic pressure, the normal excitability of somatic cells and the transmission of nerve impulses.

? If the supply of chlorine and sodium in feed is insufficient, the normal physiological function of pigs will be affected. Feed protein indigestion, rough fur, slow growth, pica, licking sewage, urine and so on. And it is easy to get infected. The content of chlorine and sodium in pig feed is limited, so it is suggested to add a certain amount of salt to the diet to meet the physiological growth needs of pigs.

Salt has the functions of sterilization, stimulating appetite, cleaning skin and decontamination, and is an indispensable thing in people's daily life. Not only people can't live without salt, but also pigs can't live without salt. If salt is correctly applied to pigs, there are also many benefits. Let's take a look.

? Salt is an edible flavoring agent, which can stimulate the saliva secretion of pigs, participate in the formation of gastric acid, and promote the activity of digestive enzymes in pigs, thus enhancing the palatability of feed and promoting the appetite of pigs, thus improving the appetite of pigs and improving the function of feed.

? Salt has the functions of sterilization, anti-inflammation, rapid hemostasis and detumescence. When a pig is injured in a fight, or the pig's neck is swollen with flying needles, salt water can be used to reduce the swelling.

Salt also has the effects of clearing away heat and toxic materials, relieving sore throat and promoting fluid production. When pigs suffer from heatstroke, they can take it once with salt 15g, brown sugar 50g and water 1000ml.

? Feeding salt to pigs has many advantages, but remember not to feed more. When adding salt to pigs at different stages, the supply should be calculated according to the proportion of air-dried diet. Generally recommended are 0.25% piglets, 0.3% finishing pigs, 0.4% pregnant sows and 0.5% lactating sows. Remember that excessive salt intake will not cause salt poisoning in pigs, which is not worth the loss.
