The roughage refers to a feed in which the natural moisture content in the feed is below 60%, the crude fiber content in the dry matter is equal to or higher than 18%, and is fed as an air-dried product. Such as pasture, crop straw, distiller's grains and so on. The nutritional value of this type of feed is generally lower than other feeds, and the digestibility of organic matter is below 65%.
Under the conditions of intensive pig raising, pigs eat compound feed mainly based on corn, soybean meal and fish meal. The increasingly "fine" feed diet, the crude fiber content is very low, resulting in digestive dysfunction, constipation and other "rich disease" in pigs, affecting the efficiency of pig raising. In fact, letting pigs eat “coarse†grain and maintaining a suitable crude fiber content in the diet is particularly effective in reducing the cost of raising and improving the performance of pigs.
Adjusting the nutrient level After the crude fiber enters the gastrointestinal tract, its volume expansion increases, which can expand the gastrointestinal volume and enable the pig to endure hunger. At the same time, the crude fiber can dilute the concentration of nutrients such as energy and protein to achieve the purpose of rational use of the feed.
Reducing the cost of feed To increase the crude fiber content of the feed diet, it is possible to replace the feed material with lower crude fiber content but higher price by partially using the feed material with higher crude fiber content but lower price, so that in the same output situation Under, the unit feed cost is reduced.
Stimulation of gastrointestinal peristalsis After entering the gastrointestinal tract, it can stimulate the peristalsis 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.
Controlling fat deposition increases the crude fiber in the feed, which lowers the serum total cholesterol and low-density lipoprotein, thus effectively regulating fat metabolism and controlling the deposition of fat in pigs.
Promoting the soluble fraction of healthy crude fiber in pigs plays an important role in reducing the secretion of gastric acid in pigs and can limit the growth of pathogenic bacteria in the intestines, thereby promoting the health of pigs.
Increasing sow reproductive performance Adding cellulose to pregnant sow diets can improve the reproductive performance of sows, with an average of 1.5 piglets per sow, and piglets produced by piglets that are not fed with cellulose. The growth rate is increased by 20%.
Of course, too high a crude fiber content in the diet will have an adverse effect on the growth and development of the pigs, and only the right amount of supply can produce the best results. At the same time, the digestive ability of the different physiological periods of the pigs is different. The appropriate proportion should be added to the diet according to the different physiological stages of the pigs and their physiological characteristics. The crude fiber content of the diet in different physiological stages of pigs is recommended as follows: 6%-8% for boars, 8%-12% for pregnant and pregnant sows, 7% for lactating sows, 6.5%-8% for reserve pigs, and 3% for weaned pigs. -4%, fattening pigs 6%-7%.
