Under the condition of intensive pig rearing, live pigs eat compound feeds such as corn, soybean meal and fish meal. The increasingly “precise†feed diet has a very low crude fiber content, which leads to digestive dysfunction, constipation and other “rich diseases†in live pigs, which affects the improvement of pig-raising efficiency. In fact, letting pigs eat “coarse†grains, maintaining appropriate crude fiber content in the diet is particularly effective in reducing the cost of raising and improving the performance of live pigs. Maintaining the appropriate crude fiber content in a live pig diet can produce the following effects: The first is to regulate nutritional levels. After the crude fiber enters the gastrointestinal tract, its volume expansion increases, which can expand the gastrointestinal volume, so that the pig can endure hunger. At the same time, crude fiber can dilute the concentration of nutrients such as energy and protein to achieve rational use of feed. The second is to reduce feed costs. In order to increase the crude fiber content of the feed diet, it is possible to partially replace the feed raw material with a lower crude fiber content but with a higher price by using a feed material with a higher crude fiber content but a lower price, so that in the case of the same output, the unit Feed costs are reduced. The third is to stimulate gastrointestinal motility. After the crude fiber enters the gastrointestinal tract, it can stimulate the motility of the gastrointestinal tract, facilitate the absorption of nutrients in the gastrointestinal tract, promote the normal excretion of feces, and reduce the occurrence of gastrointestinal ulcers. The fourth is to control fat deposition. Increasing the crude fiber in the feed can reduce serum total cholesterol and low-density lipoprotein levels, which can effectively regulate fat metabolism and control fat deposition in pigs. The fifth is to promote the health of pigs. The soluble fraction of crude fiber plays an important role in reducing the secretion of gastric acid in pigs, and can limit the growth of pathogenic bacteria in the intestine, thereby promoting the health of pigs. The sixth is to improve sow reproductive performance. Addition of cellulose to the diet of pregnant sows can increase reproductive performance of sows. The average number of sows produced per sow is 1.5, and the growth rate of the production of sows produced by the sows is lower than that of sows fed with cellulose. 20%. Of course, too high levels of crude fiber in the diet can have adverse effects on the growth and development of the pigs, and only the right amount of supply can produce optimal results. At the same time, different physiological stages of pigs have different digestibility of cellulose. According to different physiological stages and physiological characteristics of pigs, appropriate proportions should be added to the diet. The crude fiber content of pigs at different physiological stages is recommended as follows: 6% to 8% of boars, 8% to 12% of pregnant and pregnant sows, 7% of nursing sows, 6.5% to 8% of spare pigs, and 3 of weaned pigs. %~4%; finishing pigs 6%~7%.

Pigs should also eat "coarse" food if they want to be healthy
