Feeding pigs with raw feed not only saves fuel, saves money, saves labor, but also increases feed intake, promotes weight gain, and improves feed returns. (1) The choice of raw feed can be selected from the main feed of grass, such as corn, wheat, rice and other processing by-products, such as rice bran, wheat bran and so on. If these raw materials are cooked, there will be some loss of nutrients, and the feeding effect is not as good as that of raw feeding. In addition, green feed should also be fed, and most of the protein and vitamins are destroyed when cooked. However, legume seed feeds, such as soybeans, bean cakes, peanut bran, bean dregs, etc., contain an antitrypsin in the protein, which can hinder the digestion and absorption of legume protein by pig trypsin. Such feeds cannot be fed, and must be cooked at high temperature. Cooked to feed. (2) The raw feeding method can be divided into wet feeding and dry feeding. The ratio of wet feed to water should not exceed 1:2.5, otherwise it will reduce the activity of various digestive enzymes and affect the digestion and absorption of feed. The most suitable ratio should be 1:1, so that the mixed feed can squeeze out the water drops. Dry feeding is fed in the form of powder, and then fed after eating. The benefits of dry feeding: First, the feed is not easy to deteriorate, with one feeding for a few days, less labor; the second is that a variety of agricultural and sideline products can be used to make dry powder, with feeding, to open up a variety of feed sources. (3) Raw materials should be cleaned and detoxified. Feeding pigs should be cleaned and disinfected to avoid infection with parasitic diseases. The disinfection method can be soaked in lime water or potassium permanganate solution. The best method is to use the pig manure or only the fermented pig manure to fertilize the eggs in the field of planting feed to prevent egg contamination. Buckwheat, rapeseed cake, cottonseed cake, fresh cassava, etc. containing certain toxins generally need to be crushed, soaked, fermented or silaged, and then to be eaten after the toxin is removed. (4) Raw material crushing should be suitable for raw material. The diameter of the crushed particles should be 1.2--1.8 mm. This type of pig is refreshing to eat, and has a large feed intake and a long growth. The diameter is less than 1 mm, and the pig sticks to the mouth when eating, which affects palatability and is easy to cause gastric ulcer. (5) When the pure green material is fed separately, the digestive juice is most exuberant, the concentrate is rich in nutrients, the volume is small, the crude fiber is less, the palatability is good, the quality is high, and it is easy to digest, so the concentrate should be fed first. For example, if the green material is mixed and fed, the digestibility and utilization rate of the concentrate are reduced due to the large volume and water content of the green material. And too much water in the green material dilutes the digestive juice, which reduces the digestive function. (6) The amount of raw feeding should be suitable for feeding raw pigs. The feeding amount is different due to different growth stages and production performance of pigs. Piglets and fattening pigs can be allowed to eat freely; pigs are not, and they should be supplied quantitatively. Otherwise, due to excessive intake, fat deposition will affect the reproduction. Usually for non-breeding boars, the daily dosage of concentrate should be controlled at 2-2.5 kg, and the breeding period can be fed 3--3.5 kg; for sows during pregnancy, the daily dosage of concentrate is 2--2. .5 kg, lactating period is 5-6 kg. (7) To supply enough pigs to drink dry materials, supply enough water. The amount of water in winter is 2- to 3 times that of dry feed, 4 times in spring and autumn, and 5 times in summer. In particular, lactating sows and piglets should not be short of water, or they will affect the milk secretion of sows. The water quality should be clean, and the water temperature should be warm in winter and cool in summer.
