There are internal and internal causes of tail biting in pigs, and internal causes mainly refer to congenital genetic instincts. Incentives mainly refer to the inducing effects of human factors on internal factors. Some people think that tail biting is due to improper feeding and management (such as lack of food troughs, drinking utensils, feeding time is not fixed, water shortage time is too long, can lead to fighting when eating), pigsty narrow, lack of sulfur in feed Others believe it is caused by insufficient alkali and calcium in feed, lack of protein and vitamins, and intensive feeding and lack of outdoor sports. But one thing is very important, is the lack of salt in the feed, pigs are prone to tailing phenomenon. The salt component is sodium chloride, which is the main supplier of chlorine and sodium. Sodium and chlorine are indispensable essential nutrients for animals. Sodium is mainly distributed in the blood and lymph of animals, and 93% of the bases of serum are formed of sodium. Sodium can maintain the body's acid-base balance, maintain the balance of osmotic pressure between cells and blood, so that the body tissue can maintain a certain amount of water, while also regulating the heart muscle activity. If there is a lack of sodium in the blood, the heart rate will decrease. Chlorine, together with sodium, is mostly found in the blood and lymph of animal bodies. It also maintains and regulates the acid-base balance in the body and participates in the formation of gastric acid. Gastric acid is hydrochloric acid, which activates certain enzymes. The amount of stomach acid directly affects the digestion of starch and protein and even endangers the stomach itself. Salt can increase the palatability of feed and stimulate the secretion of saliva. It is also an important feed flavoring agent. If the body does not get chlorine and sodium normally, it will affect growth, bone softening, general malaise, fatigue, nausea, vomiting, loss of appetite, drowsiness, eclampsia (chewing on the ear, bite tail), resulting in reduced productivity and even death. However, if salt is given too much at a time, it will not work. Salt can cause poisoning when the salt is given too much or the amount exceeds the standard and the water is insufficient. Under the premise of scientific and rational breeding of pigs, we must pay attention to the content of salt in the feed. Too much or too little will increase the growth of the pigs.
