The use of raw materials to feed pigs not only saves manpower and financial resources, but also increases the feed intake of pigs, promotes weight gain, reduces feed consumption, and increases feed remuneration. However, the method of feeding must be emphasized.

First, the choice of raw feed The raw feed that can choose to be fed is mainly grass seed, such as corn, wheat, rice and its processing byproducts such as rice bran, wheat bran and so on. After the above-mentioned feed was cooked, the loss of nutrients was over 13%, and the feeding effect was equivalent to only 87% of the raw feed. In addition, green feed should also be fed. When cooked, most proteins and vitamins are destroyed. However, feeds containing legume seeds, such as soybeans, bean cakes, peanut cakes, and bean dregs, contain an anti-trypsin that prevents the breakdown of legume proteins by trypsin in pigs. Therefore, these feeds cannot be fed and must be fed after high temperature treatment.

Second, the raw feed method has to pay attention to raw feed can be divided into two kinds of wet and dry feed, the ratio of wet feed and water can not exceed 1:2.50, otherwise it will reduce the secretion of digestive juice, reduce the activity of digestive enzymes, affect the feed Digestion and absorption, the most appropriate ratio should be 1:1. Stir the feed so that water droplets can be squeezed out. Dry feed is fed in powdered form and fed after feeding. The benefits of dry feeding: First, the feed is not easy to degenerate, can be fed for a few days, saving labor; the second is to facilitate the production of compound feed to the pig.

Third, the Raw Material to be disinfected raw feed to pigs should pay attention to washing and disinfection, so as not to infect the parasitic disease. The method of disinfection can be soaked with lime water or potassium permanganate solution. The best way is to plant the feed without using pig manure or unfermented manure to prevent the eggs from being contaminated. Rapeseed cakes, cottonseed cakes, fresh cassava, buckwheat, etc., containing certain toxins, must generally be crushed, immersed in water, fermented or ensiled, etc., and other toxins removed before they are fed.

Fourth, the raw material crushed should be suitable raw material crushed particles with a diameter of 1.20-1.80 mm. This type of grain pig is refreshing, has a large feed intake, and is long and fast. Its diameter is less than 1 mm. Pigs tend to stick their mouths when eating, affecting palatability, and can easily cause gastric ulcers. Diameters greater than 2 mm are rough and poorly palatability. Pigs do not like to eat.

5. When the raw material is fed separately to feed the pigs, the secretion of digestive juice is the most vigorous. The concentrate feed is rich in nutrients, small in size, with less crude fiber, good palatability, high quality, and easy to digest, so it should be fed first. If the fine green material is mixed and fed, the green material has a large volume and a large amount of moisture, which reduces the digestibility and absorption rate of the concentrate, and the excessive moisture in the green material can dilute the digestive juice, thereby reducing the digestive function.

Sixth, the amount of raw feed should be suitable for raw feed to feed the pig, the amount of feed due to different growth stages and production performance of pigs are different. Piglets and fattening pigs can be allowed to feed freely, and breeding pigs are not. They must be supplied in a quantitative manner. Otherwise, due to overfeeding, fat deposits may be caused and affect breeding. Generally, the daily dosage of boar concentrates in the non-breeding period is controlled at 2-2.50 kg, and it can be fed to 3-3.50 kg during the breeding period. For pregnant sows, the amount of condiment used is 2-2.50 kg and the lactation period is 5-6 kg.

Seven, to provide enough drinking water to feed the pigs, to supply enough water. Drinking water in winter is 2-3 times that of dry feed, 4 times in spring and autumn, and 5 times in summer. In particular, lactating sows and piglets must not be deficient in water, otherwise they will affect the sow’s milk secretion. The water quality should be clean and the water temperature should be kept cool in winter and cool in summer.

VIII. Gradual transition from feed to raw material When clinker is used to feed raw materials, there must be a transition period in which 1/3 of the material is fed to the raw material. After 3-5 days, it is changed to 2/3. Only after 3-5 days will the whole feed be changed. Otherwise it will affect the pig's feeding and weight gain. The amount of feed should be controlled in the first few days after being changed to raw materials to prevent indigestion caused by overfeeding.
