Acidification treatment
In order to compensate for the indigestion caused by insufficient stomach acid in the weaned pig, 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 5, or you can add 0.3% pepsin to the feed, which can promote digestion and inhibit intestinal tract. Reproduction of pathogenic microorganisms.
Fermentation treatment
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, mix well, add water and mix until the hand grip can form a group, loose hands (65% water content), into the container compaction fermentation, the temperature must be controlled between 35 ° C ~ 45 ° C In winter, low temperature requires plastic 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), mix each 50 kg of feed into the medicine "150 grams, plus 50 kilograms of water to reconcile, the temperature and humidity are the same as the "medicine species", and 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 to 3 kg each time, and feed some green and juicy feed after each meal.
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 it into 2 to 2.5 times 80 ° C ~ 90 ° C hot water and stir it into a paste. In order not to make the feed temperature drop rapidly, you can sprinkle a layer on the surface of the feed. Dry material about 5 cm thick, covered with wooden cover or plastic film, keep the temperature at 55 ° C ~ 60 ° C, about 3 hours ~ 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.
