Add a little spicy first. When pigs have no appetite, it is very effective to feed some peppers and peppers. Because pepper and pepper contain spicy taste, aroma and irritation, pig food can increase gastrointestinal secretion, thus accelerating gastrointestinal peristalsis and improving digestive ability. Especially, adding a little pepper to the feed of lactating sows can not only increase the feed intake of sows, but also reduce the incidence of piglets and promote early weaning of piglets.

Second, feed more sweet food. Adding a proper amount of saccharin to the pig's feed, fattening pigs love to eat, and will be fat and strong after eating; Lactating sows love to eat more, increase their food intake after eating, prevent fat loss and emaciation, and increase lactation; Piglets prefer sweetness, which not only has high survival rate, but also weans early and gains significant weight. Generally, 150 ~ 200mg is added per kilogram of feed. Add some white sugar in late spring, late summer and early autumn, add some brown sugar in early Spring Festival Evening, autumn and winter, and add1~ 3g per kilogram of feed, which is better than saccharin.

Third, it's a little salty. Adding proper amount of salt (no more than 6 grams per day) to pig diet can promote pig metabolism and growth, increase water consumption, improve feed palatability, stimulate appetite and help digestion.

Fourth, don't forget to add some acid. Adding 10 ml vinegar to each kilogram of feed (diluted with water) and stirring evenly will not only help pigs eat, but also help digestion. Because vinegar contains amino acids and other nutrients, it is very beneficial to the growth and development of pigs, but it should not be added too much.
