First, acidification treatment In order to compensate for the indigestion caused by insufficient gastric acid in weaned piglets, the feed should be acidified. You can add 1%-3% citric acid or lactic acid to drinking water or feed to reduce the pH of the feed to about 5, or you can add 0.3% pepsin to the feed, which can promote digestion and inhibit intestinal tract. The reproduction of pathogenic microorganisms. Second, the fermentation process Take 50 grams of baking soda, liqueur, sea bream powder, spicy glutinous rice, 3 bags of Liuyi, 5 grams of tea, Guanzhong, 250 grams of yam, medlar and dried tangerine peel, 500 grams of glucose, separately ground and mixed, then added 5 egg whites, 6 kilograms of fine rice bran and mix well, add water to adjust to the hand tightly to form a group, loose hands and disperse (water content about 65%), put into the container compaction fermentation, the temperature must be controlled at 35 ° C -45 ° C In the meantime, low temperature in winter requires plastic (10280, 30.00, 0.29%) film and other insulation. After 3 days, when the material is yellow and has a strong aroma of sweet apple, it is a homemade "medicine strain", which is open and kept in the shade to dry. When feeding, according to the ratio of roughage powder 40%, wheat bran 10%, bone meal 2%, fish meal 2%, corn 45%, compound feed additive (trace element), every 50 kg of feed mixes with the drug "150 grams, plus 50 kilograms of water, the temperature and humidity are the same as the "medicine", then the feed is placed in a container and fermented for 24 hours. When a strong liqueur apple scent is produced, it can be fed. Feed 4 times a day, feed 2 kg - 3 kg each time, and feed some green and juicy feed after each meal. Third, saccharification treatment The concentrates such as corn, barley and sorghum are rich in starch. If saccharification is carried out, some of the starch can be converted into maltose, which not only improves the palatability of the feed, but also makes it easier to digest. First, put the crushed concentrate into a container, then pour 2 to 2.5 times hot water from 80 ° C to 90 ° C to stir it into a paste. In order not to let the feed temperature drop rapidly, a layer of the feed can be sprinkled. Dry material about 5 cm thick, covered with wooden cover or plastic film, keep the temperature at 55 °C-60 °C, about 3-4 hours to make the feed saccharification, saccharified feed, storage time is best not to exceed 14 hours, with the system as appropriate to avoid rancidity.
