First, acidification. After early weaning of piglets, the source of lactic acid is interrupted and gastric acid secretion is still less, which seriously affects digestion. Acidification of feeds for weaned piglets should be performed. You can add 1-3% citric acid or lactic acid to your pig's drinking water or feed to lower the pH of the feed to 5. You can also add 0.3% pepsin to feed to facilitate digestion.
Second, fermentation. Take baking soda, sweet melody, sea salt powder, spicy wolfberry each 50 grams, Liu Yisan 3 bags, 5 grams of tea, Guanzhong, yam, wolfberry, dried tangerine peel 250 grams, 500 grams of glucose, respectively, into the end of mixing, Add 5 egg whites, 6 kg of fine rice bran and mix well. Add water to reconcile until tightly grasped. Into a mass. When loosening and loosening (moisture content is about 65%), put it in a container such as a barrel or a cylinder and compactly ferment. The temperature should be controlled at 35°C-40°C. After 3 days, when the material is yellow and has a strong liqueur apple aroma, it is a ready-to-use medicinal herb, which is dried in a cool, open place for use. When feeding, 40 parts of roughage powder, 10 parts of wheat bran, 2 parts of bone meal and fishmeal, 45 parts of corn, and 1 batch of compound feed additives (microelements) were mixed. Each 50 kg of ingredients mixed with 150 grams of medicinal herbs, plus 50 kg of water to reconcile, into the container by the 24-hour fermentation, to produce a strong rum aroma of apple, you can feed. Feed 4 times a day, 2-3 kilograms each time, and mix with some green and juicy feed after each meal. Feeding pigs with this fermented feed, pigs like to eat long, fur light, just 45-60 days to 30 kg of medium-sized pigs can be slaughtered.
Third, worse. Non-digestible, poorly-differentiated crude fiber feed, such as clams, leaves, and straw powder, can be made soft and fragrant after being processed to make pigs love it. The method is: first put the raw materials into the tank or soak in the soft, remove and then dry until the hand grasps the material from the fingers can slowly dripping out of the water on the pot steamed. In order to make the raw material steamed, it is best to start steaming the night before, and then cook it again the next day. After the ingredients are panned, when the temperature drops to about 35°C, add 7.5-10 kg of fresh distillers grains or 250 grams of distiller's yeast per 50 kg of steamed ingredients. Mix well and put the cylinders closed. In spring, summer, and autumn, it is not possible to warm the interior of winter, and it is advisable to keep the room temperature at 20°C or so. After 7-10 days, the feed can become fragrant and delicious.
Fourth, saccharification. Concentrates such as corn, barley, and sorghum are rich in starch and can be partially converted to maltose by saccharification, which not only improves feed palatability, but also facilitates digestion. The preparation method is: first put the crushed fine material into a wooden barrel or a cylinder, then pour 2-2.5 times hot water at 80°C-90°C, and fully stir into a paste. In order to prevent the feed temperature from falling rapidly, a layer of dry material about 5 cm thick may be sprinkled on the surface of the feed, covered with a wooden lid or plastic film, so that the temperature is maintained at 55°C-60°C, after saccharification for 3-4 hours. Feeding. The storage time is preferably not more than 10 hours.
